x402-protocol-integration

x402 revenue reconciliation API for sellers: aggregate settled USDC payments across all your x402 endpoints by payTo address and time window. Return per-endpoint earnings, transaction counts, distinct payer reach, and net revenue, reconciled against CDP Facilitator settlements. Use it to attribute income, audit payouts, build accounting reports, and spot underperforming routes — one call, paid in USDC, no dashboard login required.

Refresh the live readiness evidence, canonical JSON profile, and badge for one existing paid Ontario x402 service listing after its included 30-day maintenance window. Payment buys a new observation, not a better grade, metadata edit, ranking, or traffic.

Paid test endpoint — verifies that AI agents can successfully complete X402 micropayments

Every seller in the x402 Bazaar as one CSV (2,046 rows), ranked by paid calls in the last 30 days: listings, calls, unique payers, last call, price range, networks, sample description.

Debug an x402 payment before you submit it — why does USDC answer invalid signature? Verifies the EIP-3009 transferWithAuthorization (EIP-712 signer, v, low s, validity window) and the seller's terms (payTo, amount, asset, network, bound nonce), and names the domain a failing signature was really made for, e.g. Base Sepolia's 'USDC' used for Base mainnet's 'USD Coin', the commonest reason an x402 payment reverts. Offline, deterministic, signed answer.

Web search for AI agents with no signup, no API key, no account. GET /search?q=... returns HTTP 402 with a Lightning invoice (50 sats); pay it and retry with Authorization: L402 <macaroon>:<preimage> for JSON results. Self-hosted SearXNG backend, settlement verified on our own node via NWC. Companion MCP client: npm i l402-search-mcp.

Renew your 402post listing for another 30 days: $0.10 USDC. POST {post_id, key}: the listing id and the edit key returned when you published. Same service: publish https://402post.com/v1/posts; feature https://402post.com/v1/featured.

Put your 402post listing at the top of its lists for 7 days: $0.50 USDC. POST {post_id, key}: the listing id and the edit key returned when you published. Same service: publish https://402post.com/v1/posts; renew https://402post.com/v1/renewals.

Compare one x402 resource's Coinbase Bazaar discovery visibility with a caller-held baseline: merchant presence, discovery metadata, schema metadata, visible payment fields, and top-20 position for 1–3 buyer queries. Not a VM05 replacement, direct payment-contract probe, global rank, or remediation advice.

Most used x402 paid services from the public x402 Bazaar catalog: unique payers and calls in 30 days, price, networks and description, plus ecosystem totals. Optional keyword filter. See what agents actually buy.

Check any x402 endpoint before paying, without paying: price in USD per network, asset (flags anything that is not official USDC), pay-to address and whether it is a contract, authorization timeout, Bazaar metadata, and risk alerts with a clear verdict.

API/URL health check: up or down, HTTP status, latency, and whether the endpoint is a valid x402 paid endpoint.

Explain an EIP-712 typed-data signature before signing it: x402/EIP-3009 payment authorizations, EIP-2612 permits, Permit2 and Seaport orders. Flags unlimited allowances, long validity and non-official tokens, and returns the exact hash to compare with your wallet.

Status of x402 facilitators (who verify and settle payments): live check of each one's /supported endpoint with latency, x402 versions, schemes and networks, plus on-chain settled volume over 24h, 7d and 30d (x402-list data). Choose a facilitator or debug failing payments.

Status of x402 facilitators (who verify and settle payments): live check of each one's /supported endpoint with latency, x402 versions, schemes and networks, plus on-chain settled volume over 24h, 7d and 30d (x402-list data). Choose a facilitator or debug failing payments.

Search x402 paid services in the Bazaar by keyword (e.g. weather, solana, search) ranked by real usage, with price, networks and ready-to-pay URL. Lets an agent find the service it needs.

Test your x402 client or agent for the minimum price: confirms the payment arrived and echoes back the network, scheme, payer and amount the server saw, your IP, user agent, time and any 'eco' text you send.

Diagnose the book's common mistakes from supplied signals; no unsupported probabilities are assigned. Paid per call via x402; no API key required.

Fetch one public static HTML page after robots and public-address checks, then return bounded readable text, title, final URL and source links. Standard x402: POST the URL, sign the 402 and resend the same body. The 402 also returns an encrypted payment_request that pays for exactly the quoted fetch. No browser, login, summary or full-site crawl.

Score up to 100 x402 endpoints in one call. For teams: per-agent spend limits and an audit trail at lumierepaycheck.org/subscribe.

Watch an x402 endpoint for 30 days: webhook alerts when it goes down, changes payout wallet, raises its price, or fails a paid delivery check.

Render one public page in headless Chromium after robots and public-address checks, wait for scripts to settle, then return bounded visible text, title, final URL and source links. Standard x402: POST the URL, sign the 402 and resend the same body. The 402 also returns an encrypted payment_request that pays for exactly the quoted render. Failed renders are never charged. No login, interaction, screenshots or full-site crawl.

Order a data pipeline and receive a Docker image. Pay over x402. The image pulls data from a source such as weather, Google Drive or Confluence, stores it and serves the results to your agent over MCP. The platform builds and tests the image first and settles the payment after the test.

Audit a public HTTPS x402 API without payment: HTTP 402 challenge metadata, Bazaar and well-known discovery, OpenAPI 3.1 operation schemas and payment declarations, redirects, latency, and security headers.
