Find the best x402 paid API for your need across the CDP Bazaar catalog: full-text search by keyword, filter by max price per call and network, ranked by measured 24h uptime then price. Each result includes live health data (uptime percent, average latency) that the official catalog does not have. The comparison-shopping layer for agent commerce.

ShieldAPI - x402 security preflight before agents trust an identity, sender, or email counterparty

Classify an HTTP outcome for retry and remediation without returning its body. 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.

Extract English machine-printed text from one caller-supplied PNG, JPEG, or WebP locally for $0.01 USDC via x402. Returns bounded text, confidence, and SHA-256 receipt; no URL fetch, storage, or paid vision provider.

POST JSON: {"event":{id,pubkey,created_at,kind,tags,content,sig},"checkZap":false} Verifies id/sig. checkZap extracts kind-9735 bolt11; preimage proves zap settlement. Does not hit relays. Spec: https://api.major-miners.com/.well-known/l402-services

POST JSON: {"text":"hello","type":"uppercase"} type=uppercase|reverse|leetspeak|morse Demo transform. Prefer LNURL / Nostr / preimage_verify on this host. Spec: https://api.major-miners.com/.well-known/l402-services

POST JSON: {"target":"user@domain"} optional amountSats for a BOLT11. Does not pay. Lightning-native: resolve LN addresses / LNURL-pay. Spec: https://api.major-miners.com/.well-known/l402-services lnget -X POST -H "content-type: application/json" -d '{"target":"victoriousinnovation563427@getalby.com"}' https://api.major-miners.com/api/lnurl

Count likely personal-data classes without echoing detected values. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

Detect removed OpenAPI paths and methods before an agent deploys a client-breaking change. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.
