x402-protocol-integration

Get YOUR x402 endpoint listed in this Bazaar - done for you, $99 one-time. You receive a deploy-ready x402 v2 kit generated for your stack (Next.js, Express, serverless; PHP via a free serverless function) with your wallet, price and discovery declaration baked in, plus a resumable listing_key that drives the automated pipeline via MCP (https://mudko.com/api/mcp): validate against Coinbase's own preflight with per-check fixes, and when your price is $1 or under WE fire the indexing settlement from our funded wallet. Ends with a receipt: settle tx + your live merchant-feed entry. Built by the team that listed its own endpoints first (this very listing is dogfood). Keepalive add-on available so you never fall out of the index.

Find duplicate record groups using canonical fingerprints without returning record values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

Evaluate an untrusted path for unsafe parent-segment signals without returning secret data. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible…

Identify statistical outlier indexes in bounded numeric samples. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

Paid inference on Base USDC via x402; returns a signed receipt + verify_url. Unmetered OpenAI path is POST /v1/chat/completions (not this resource). Paying this host is real Base mainnet USDC.

Split host and optional port from a host:port or URL authority string — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that a…

Does a catalogue listing still match what the origin serves? Calls the resource with no payment, reads the price, network and payTo out of the 402 the origin itself returns, and compares them with the price the catalogue advertises. The 402 is the authoritative statement; the catalogue is a cache of one. Also separates two failures no catalogue reports: an origin that is gone, and an origin that answers but whose response headers exceed the 16384-byte ceiling Node applies to all response headers combined -- live, indexed and impossible to pay from a Node client. Required: resource. Optional: advertised_price. Honest note: demand for this route is not measured; it exists because the defect it reports was measured on our own surface first.

Evaluate data age against a caller-supplied freshness objective. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

Classify operational incident severity from explicit impact signals. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

Screen untrusted text for common cross-site scripting signals without echoing it. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

Check tests, rollback, observability, ownership, and security review before deploy. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.

Test endpoint for verifying x402 payment integration end to end. Returns a static greeting in the Agent Tollbooth standard response envelope. Not a data product — use it to smoke-test your x402 client for $0.001 before calling our compliance endpoints: OFAC sanctions screening ($0.01) and FDIC bank verification ($0.01), listed under this same payTo address.

Detect gaps larger than an expected interval in ISO-8601 timestamps. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production controls.
