# PaperPilot Tools — buyer-focused technical services

> AI-assisted original software from one actual economic owner. This site is a free public guide, not an instant payment gateway. Prices are conditional offers until a real buyer agrees to their terms.

## Free public examples
- [Free local CSV checker](https://livastic-vm1-primary.github.io/paperpilot-tools/csv-quality-api.html#local-preview): runs inside your browser, up to 32 KiB UTF-8, no upload, login or payment. Structural warnings, not proof of correct accounting or safety.
- [Installable zero-charge CSV preflight agent skill](https://github.com/livastic-vm1-primary/paperpilot-tools/tree/main/.agents/skills/paperpilot-csv-preflight): `npx skills add livastic-vm1-primary/paperpilot-tools --skill paperpilot-csv-preflight`, then run its included `scripts/preflight.cjs --demo` locally; up to 32 KiB UTF-8, no input upload, no wallet, no auto-payment. An optional **separate** VM5 paid API is buyer-authorized only.
- [Free synthetic merchant example](https://vm5-openapi-x402.onrender.com/v1/csv-sample): GET, fictional data, no purchase.
- [Korean freelance estimate guide](https://livastic-vm1-primary.github.io/paperpilot-tools/freelance-estimate-ko.html): illustrative calculation, not a certified tax invoice.

- [Free x402 v2 quote decoder](https://livastic-vm1-primary.github.io/paperpilot-tools/x402-inspector.html): read the PAYMENT-REQUIRED header/unsigned JSON locally. Shows Base USDC asset address, 6-decimal amount, recipient payTo, bounded server-reported error text (unverified) and warnings; compare buyer-supplied EXPECTED USDC invoice amount with the 402 quote EXACTLY and fail-closed on independent publicly reported 0.10-versus-1000USDC placeholder/merchant invoice_not_found flags. A matching amount never authorizes a real wallet. No network fetch, wallet, account, signing, charge or fraud/merchant-identity certification. No user adoption or payments assumed.

- [Free local trade-ID CSV duplicate audit](https://livastic-vm1-primary.github.io/paperpilot-tools/tradeid-audit.html): spot exact repeated rows, repeated/missing stable trade/fill/execution/order identifiers, and equal amounts with DISTINCT IDs; refuse amount-only conclusions. Up to 256 KiB / 750 rows, local-only, no wallet/payment/analytics, no actual sales or tax verdicts. Optional existing 15 USDC DeFi exception review is a separate written buyer-authorized pilot, not an automatic checkout.

- [Verified free opt-in Trade-ID review quote inquiry](https://livastic-vm1-primary.github.io/paperpilot-tools/contact.html?service=tradeid-review): one already activated login-free consent-required FormSubmit email form, preselected original 15-native-Base-USDC up-to-50-anonymized-rows pilot; NO payment/charge on enquiry, terms require individual written agreement, no customer yet.
- [Optional original 15 native Base Circle USDC manual Trade-ID CSV review on Clawlancer](https://clawlancer.ai/marketplace/94393ff6-eef4-4a25-8645-d679145c9edf): one buyer-authorized nonconfidential/anonymized exchange trade export up to 50 rows, row-number evidence separating exact duplicates from equal quantities with different IDs, scoped human-reviewed report. PUBLIC active FIXED listing using same one-owner VM1 seller wallet; verified purchases=0, paid buyer/order and escrow release NOT independently tested, and user must check marketplace funding/terms. The observed signed-out human listing calls this seller FIXED offer “Bounty / Open for claims” and has no visible buyer purchase button, so it is NOT verified one-click checkout. Use the separate opt-in FormSubmit inquiry instead. Separate from free local-only checker and any tax advice.

- [Free offline EVM explorer CSV hash-discovery reference](https://github.com/livastic-vm1-primary/paperpilot-tools/tree/main/examples/evm-explorer-hash-preflight): Python3 stdlib source and 20 fictional local tests for Etherscan-like Transaction Hash imports; dedup only for RPC lookup, NEVER economic Transfer logs; 5,000 row warning and fail-closed chain identity caveat. Third-party rotki project did not commission or approve it. No network or wallet.

- [Free browser-only USDC invoice ↔ Transfer CSV exception candidate preview](https://livastic-vm1-primary.github.io/paperpilot-tools/usdc-invoice-reconcile.html): Base8453 exact Circle token address, six-decimal BigInt arithmetic, row-numbered candidate exact/partial/overpaid plus strict duplicate event/chain/token/to-address/ref quarantine. Entirely local, no network, uploaded invoices, wallet connection or proof of real transfer/finality; synthetic demo available. Merchants must check real canonical transfer logs independently.
- [Opt-in proposed USD 49 per pilot USDC invoice reconciliation inquiry](https://livastic-vm1-primary.github.io/paperpilot-tools/contact.html?service=usdc-invoice-pilot): an original existing activated contact form with explicit third-party FormSubmit consent, up to 50 anonymized report candidates, no checkout or payment on inquiry. The 49 USD rate is unvalidated hypothesis, independently authorized real client contracts=0, actual separately attributable receipts=0. Merchant scope, Base USDC exact amount, KYC/payee where legally needed and terms need explicit written agreement.

- [Free local-only manual Koinly column mapper](https://livastic-vm1-primary.github.io/paperpilot-tools/koinly-column-mapper.html): explicit source header selection into original Simple/Trades/Universal Koinly field names, no dropped or merged rows, preserved original unused columns, UTC checkbox required, source-formula injection blocked, output candidate file downloaded only on separate user action. No Koinly login, remote data upload, wallet, imported tax results, claims of paid users or official vendor endorsement. Complements the separately developed SAME-OWNER VM3 Koinly format preflight.

## Optional paid APIs
- [Optional human browser USDC checkout (beta)](https://livastic-vm1-primary.github.io/paperpilot-tools/csv-usdc-checkout.html): local CSV preview stays free/private; visitor separately consents to hosted sample upload, obtains a fresh read-only 0.005 Base Circle USDC price quote, connects their own EIP-1193 wallet, explicitly opts in and reviews exactly one EIP-3009 authorization with no automatic retry. Real buyer-paid POST success NOT independently verified; never treat a quote or connected wallet as income.
- [VM5 CSV preflight buyer instructions](https://livastic-vm1-primary.github.io/paperpilot-tools/csv-quality-api.html): POST https://vm5-openapi-x402.onrender.com/v1/csv-preflight, currently 0.005 native Circle USDC on Base mainnet (eip155:8453) per valid buyer-authorized x402 v2 request. The current unsigned valid request returns HTTP 402; malformed input returns HTTP 400 before payment. Quotes are NOT purchases. No independently verified paid POST customers at this time.
- [Actually active FIXED 9-native-Circle-Base-USDC x402 402 header byte-budget private report](https://clawlancer.ai/marketplace/e072b639-4235-428f-89ad-966c0682dbf9): one owner-authorized public unsigned x402 header and optional fictional invoice amount; paid written limited remediation, not automatic free preview, route repair or wallet action. Active listing independently checked 2026-10-20, ZERO orders and payout. Factual synthetic QA example at https://livastic-vm1-primary.github.io/paperpilot-tools/docs/X402_HEADER_BUDGET_FICTIONAL_SAMPLE.json; AI-assisted, no private values.\n- [Optional original 49-native-Base-USDC one-route x402 merchant invoice-price & browser-CORS QA](https://livastic-vm1-primary.github.io/paperpilot-tools/services.html#x402-audit): hypothetical buyer-approved 0.10-vs-1000 USDC expected invoice mismatch and vendor-issued invoice_not_found flag, plus public OPTIONS preflight; one written-scope merchant path only, no private invoices or wallet signing. Original real independent user report at https://github.com/bitrefill/agents/issues/11 (NOT paid to our service), currently 0 paid customers.
- [Optional VM5 x402 quote structure API](https://vm5-openapi-x402.onrender.com/v1/docs): distinct existing GET /v1/x402-preflight, 0.010000 native Base Circle USDC per separate buyer-authorized x402 v2 request. Free fictional hosted demonstration: https://vm5-openapi-x402.onrender.com/v1/x402-sample . No independent customer-paid orders verified for this route; GET 402 challenge alone is not a sale.
- [Original merchant public API specification](https://vm5-openapi-x402.onrender.com/v1/docs): read current price and parameters BEFORE considering a paid request.
- [Original buyer quickstart](https://github.com/livastic-vm5-primary-20260911/x402-openapi-lint/blob/main/docs/CSV_REAL_DATA_BUYER_QUICKSTART_20261020.md): independent buyer controls signature and payment. Never send secrets or private CSV just to test a route.
- A distinct paid-and-delivered synthetic GET /v1/csv-report has previously been verified for this same-owner merchant. This does not establish any paid POST /v1/csv-preflight order.

## Custom paid work — agreement first
- [Free two-export crypto transfer candidate review (same-owner VM3)](https://livastic-vm3-primary-tmp-260920.github.io/defi-payment-proof-qa/guides/crypto-transfer-csv-pair-auditor.html): compare authorized exchange withdrawals and wallet receipts locally, report ambiguous/missing/duplicate/fee/time pairs and handle Kraken Ledger internal IDs without claiming onchain verification. A distinct original public site but the same one human beneficial owner, no RPC, wallet, data upload, tax lots or external paying customers.
- [Free DeFi transaction CSV exception inbox](https://livastic-vm1-primary.github.io/paperpilot-tools/defi-exception-inbox.html): EVM wallet/explorer CSV (up to 256KiB / 750 rows) analyzed entirely locally for multi-event transaction hashes, possible LP/bridge/staking/borrow method review, missing or malformed values. Exports unresolved row-number checklist only, with full public transaction hashes OFF by default. No key, wallet connect, swap, price, gain/loss or tax classification. Firstparty test cases, no external customer endorsement.
- [Optional fifteen-native-Base-USDC DeFi CSV exception review pilot](https://livastic-vm1-primary.github.io/paperpilot-tools/defi-exception-inbox.html#pilot): at most 50 flagged EVM data rows for a manual factual review checklist, only with buyer's written lawful approval and data/payout terms. No tax advice, no instant checkout, real purchase or completed client to date. User-requested feedback email and public issue link on tool page; no sensitive data requested.

- [CSV import audit — free local script and optional 25 native Base Circle USDC fixed-scope manual pilot](https://livastic-vm1-primary.github.io/paperpilot-tools/csv-import-audit-service.html): 1 authorized non-confidential CSV <=2MiB, <=10,000 data rows, <=25 columns, up to 3 mutually agreed cleanup or mapping rules, exception list, reusable Python script, 1 correction; **NO checkout until exact terms in writing; actual sales 0**. Free Python 3 script checks structural issues offline without upload or wallet and is not a CSV correctness/financial certification. Distinct from automated existing 0.005USDC API.

- [Services and technical proof](https://livastic-vm1-primary.github.io/paperpilot-tools/services.html): bilingual invoice templates (indicative from USD 99), scoped offline web utilities (from USD 249) and browser automation QA (from USD 149). These are starting quotes, not active checkouts or guaranteed delivery.
- [Manual PaperPilot offline-kit order inquiry](https://livastic-vm1-primary.github.io/paperpilot-tools/order.html): proposed 5 native Base Circle USDC for one internal-team licence. No instant checkout, no escrow, no completed PaperPilot buyers; agree actual scope, lawful payment and refund terms in writing first.
- [Opt-in customer inquiry](https://livastic-vm1-primary.github.io/paperpilot-tools/contact.html): consent-based third-party FormSubmit inquiry, not a payment order. Please do not send passwords, keys, customer files, private data, or wallet recovery phrases.

- [x402 merchant CORS self-check and optional fixed-scope audit](https://github.com/livastic-vm1-primary/paperpilot-tools/blob/main/docs/X402_BROWSER_CORS_SELLER_AUDIT.md): original free Node script to evaluate owner-provided OPTIONS headers OFFLINE; no fetch/wallet/charge. Optional diagnostic of one authorized merchant URL + one browser Origin at indicative 49 native Circle Base USDC, only after buyer-accepted written contract and genuine payout eligibility. ZERO completed QA customers, no instant checkout.

- [Machine-readable POST-only x402 CSV discovery and safe unpaid quote sample](https://livastic-vm1-primary.github.io/paperpilot-tools/x402-post-discovery.json): POST-only VM5 customer CSV quality service, exact synthetic application/json body required before HTTP 402, real native Circle Base8453 USDC 0.005 quote, receiver/token/CORS metadata and independent third-party unpaid 402 reproduction. GET/HEAD or invalid POST do not discover paid route. This public document never signs/pays, is not buyer agreement or paid POST proof; confirmed independent paid buyer-owned POST customers ZERO.

- [Google Workspace invoice intake, free sample source and optional 95-USDC fixed-scope QA](https://livastic-vm1-primary.github.io/paperpilot-tools/services.html#workspace-invoice-intake): free local source at https://github.com/livastic-vm1-primary/paperpilot-tools/tree/main/examples/google-workspace-invoice-staging with 19 offline mock tests. Gmail-to-private Drive/InvoiceStaging Sheet; preview only by default, human opt-in before archive and no real owner Gmail customer account access claimed. Optional one TEST label/folder/sheet with up to ten fictional PDFs for indicative 95 native Circle Base USDC, written purchaser contract, legal payee, cancellation and receipt verification first. Confirmed paying customers ZERO.

## Machine-readable public details
- [Product and offer catalog](https://livastic-vm1-primary.github.io/paperpilot-tools/catalog.json): static JSON with exact status and payment distinctions.
- [Public project source](https://github.com/livastic-vm1-primary/paperpilot-tools): code and free checker tests.

Never treat a HTTP 402 quote, catalog listing, proposal, email or previous unrelated receipt as a new payment or buyer. All service availability and API parameters are subject to provider verification.

- [Optional x402 merchant/user feedback](https://livastic-vm1-primary.github.io/paperpilot-tools/x402-inspector.html#buyer-feedback): select the actual client/observed issue and *nonbinding* interest level. Submission requires explicit consent to third-party FormSubmit; only selected controls, optional email and short nonsecret note are sent on click. The free pasted public quote is NEVER included. This is not a paid order or verified independent buyer.

- [Original Crypto CSV Rescue, free 50-row wholly fictional exception queue + optional nonbinding $49 manual pilot](https://livastic-vm1-primary.github.io/paperpilot-tools/crypto-csv-rescue.html): repeated exported rows, missing acquisition-source reference questions, unpaired sends/receives, asset/amount/hash inconsistencies; does NOT file tax returns, assign cost basis, sign a wallet or upload confidential CSV. Scope request via original activated consent-gated FormSubmit contact page only; real source data are never allowed in the inquiry. Zero verified paying users of this pilot, no instant checkout. Distinct from narrow 15 native Base USDC Trade-ID-only review.

- [Reproducible unpaid x402 CSV buyer quote (2026-10-21)](https://livastic-vm1-primary.github.io/paperpilot-tools/docs/CSV_005_UNPAID_BUYER_VERIFICATION_20261021.md): fixed fictional CSV and two explicit no-wallet HTTPS requests prove live 402 price 0.005 native Base Circle USDC and browser CORS204, NOT signed payment, paid HTTP200, customer data, independently verified settlement, outside purchase or owner new income. Source https://github.com/livastic-vm1-primary/paperpilot-tools/blob/main/examples/verify-csv-x402-unpaid.mjs (requires explicit --live-unsigned-check).

- [Privacy improvement: actual local-first CSV buyer quote for one 0.005 Base Circle USDC x402 POST](https://livastic-vm1-primary.github.io/paperpilot-tools/csv-usdc-checkout.html): **free price quotation uses only a built-in fictional CSV**, never the actual visitor-selected input; no wallet or customer file needed for price. Only an explicitly buyer-signed and separately consented paid POST can transmit the original CSV. Strict fixed merchant price/recipient guard, no automatic signing, no transaction retry; still NO independently proven buyer-owned paid POST success or new income. Previous v0.1.0 public release notes document an older consented quote-upload beta; current source behavior supersedes that older UX.
- [Original independent CSV x402 buyer quote privacy details](https://livastic-vm1-primary.github.io/paperpilot-tools/docs/CSV_005_PRIVACY_FIRST_FICTIONAL_QUOTE_20261021.md): the current VM1 price quote sends only SOURCE-CONTROLLED fictional CSV, no visitor payload, no upload consent or wallet required; a real authorized buyer CSV is transferred only on a separate one-time paid POST after explicit buyer signature, with no retry. This changes older v0.1.0 consented-upload quote UX but never claims real buyer-funded success or new USDC income.
