How this service works
Ranked discovery over the live x402 service market: every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision.
Output
A JSON object containing a ranked array of up to 25 BTC-tagged x402 services, each with its name, network (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes query metadata (route, matched count, limit, operator), a snapshot hash for verifiability, scoring revision, and a generatedAt timestamp.
Example use cases
Finding popular BTC payment APIs
“Which x402 services tagged with BTC are getting the most real usage right now? I want to see the top ones ranked by paying wallets over the last 30 days so I can pick the most battle-tested one.”
Monitoring BTC service market trends
“Pull the current leaderboard of btc-tagged x402 services for me — I want to track how call volume and unique payers are shifting week over week to spot emerging bitcoin API providers.”
Evaluating BTC API landscape for integration
“I'm building something on top of bitcoin APIs — can you fetch the ranked list of BTC-tagged x402 services with their prices and 30-day call counts so I can compare my options before committing to one?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-btc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a ranked, usage-verified discovery of BTC-tagged x402 services — it provides real 30-day signal (calls and paying wallets) rather than static listings. Prefer it over generic x402 explorers when the user wants to find the most proven or popular bitcoin-related APIs, or when verifiability via snapshot hash matters. Use sibling endpoints for other tag categories (stocks, macro, fun, etc.).
Side effects
- No BTC-tagged services indexed — returns empty services array with count:0
- Snapshot stale — generatedAt timestamp may lag real-time by indexer delay
- Payment not processed — 402 response if USDC payment not attached
- Worker timeout — Cloudflare Worker cold start may cause latency spike
- Schema mismatch — input schema is minimal; malformed query params silently ignored
