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 AI-agent-tagged x402 services, each with name, network chain, 30-day call count, 30-day payer count, USD price, and resource URL. Also includes total matched service count, the query parameters used, a generatedAt timestamp, and a snapshot receipt (hash + scoring revision) for auditability.
Example use cases
Discovering trending AI agent APIs
“What are the most-called x402 APIs tagged for AI agents right now? Show me the top 25 ranked by 30-day call volume so I can see which services real agents are actually using.”
Vetting a micropayment API before integrating
“Before I build my agent on top of an x402 service, can you pull the ranked list of ai-agent services and show me which ones have the most paying wallets over the last month — I want something proven, not a ghost API.”
Competitive benchmarking for an x402 service owner
“I just launched an x402 API tagged as an AI agent tool — can you check the bazaar rank leaderboard and tell me how many calls and paying wallets the top services have so I know where I stand?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-ai-agentsWhen to prefer
Use this endpoint when you need an objective, usage-backed ranking of x402 services specifically tagged for AI agents — not just a directory listing. It is the right choice when you want to filter by real 30-day economic activity (paying wallets, call volume) rather than self-declared metadata, and when you need an auditable snapshot receipt for reproducibility. Prefer alternatives if you need cross-tag queries, non-AI-agent categories, or historical time-series data.
Side effects
- No services indexed yet — returns empty services array with count 0
- Snapshot unavailable — may return stale or error if the ranking worker is mid-update
- Rate limit exceeded — HTTP 429 if called too frequently without payment
- Payment failure — HTTP 402 if the $0.008 USDC micropayment is not attached or rejected
- Network timeout — Cloudflare Worker cold-start or upstream indexer delay
