How this service works
An open index of the machine-to-machine (agent) economy. x402 routes: 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. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.
Output
A JSON object containing a ranked array of up to 25 services tagged 'watch', each with name, network ID (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes total matched count, the query parameters used, the route, who declared the data, and a generatedAt ISO timestamp plus snapshot hash for auditability.
Example use cases
Leaderboard of watch APIs by payers
“Pull the current leaderboard of x402 watch-tagged services ranked by how many unique paying wallets have used them in the last 30 days — I want the top 25 with their prices and call volumes.”
Vetting a watch service before integrating
“Before I integrate a watch-category x402 API into my agent, can you check the bazaar rank to see which ones have the most real usage this month and give me the snapshot hash so I know the data is fresh?”
Market research on x402 watch ecosystem
“I'm researching the x402 watch-API ecosystem — can you fetch the ranked list of services by payer count for the last 30 days and tell me how many total matched services exist beyond the top results?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-watch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need ranked, usage-verified discovery of x402 services specifically in the 'watch' category, with real 30-day signal (calls and paying wallets) rather than self-reported metadata. Prefer it over generic API directories when you want proof-of-activity scoring and a cryptographic receipt for auditability. Best when building agent workflows that need to select the most battle-tested watch-category micropayment APIs.
Side effects
- No services indexed under 'watch' tag returns empty services array with count 0
- Payment not included or invalid returns HTTP 402 requiring x402 payment
- Worker unavailable or cold-start timeout returns 5xx error
- Malformed query parameters may return 400 with error detail
- Snapshot data may be stale if indexer has not updated recently
