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 x402 probability-tagged services, each with name, network (e.g. eip155:8453), 30-day call count, 30-day unique paying wallets, price in USD, and resource URL. Also includes query metadata (operator, limit, matched count, route), a generatedAt timestamp, the snapshot hash, and the scoring revision — so the agent can verify freshness and reproducibility of the ranking.
Example use cases
Find active forecasting APIs for an agent
“I need to pick a probability or forecasting API to plug into my agent — can you show me which x402 services in the probability category have the most real usage and paying users over the last 30 days?”
Vet x402 market before integrating
“Before I build on an x402 probability service, can you pull the current ranked list so I can see which ones have genuine call volume and aren't just empty listings?”
Compare market demand across probability services
“Show me a ranked leaderboard of x402 services tagged with probability — I want to see the call counts, unique payers, and prices so I can compare demand across options.”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-probability?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, usage-weighted ranking of x402 services specifically in the probability or forecasting domain, rather than a static directory or self-reported listing. It is the right choice when you want to compare services by real 30-day payment activity (not just registration), need a verifiable snapshot hash for auditability, or are building an agent that auto-selects the best probability API based on market demand. Prefer alternatives if you need a different tag category, want full-text search, or need richer service metadata beyond call/payer stats.
Side effects
- No services indexed under the probability tag — returns empty list with count:0
- Snapshot index stale or temporarily unavailable — may return cached or error response
- Payment of $0.008 USDC not fulfilled — 402 response blocking access
- Malformed query parameters — returns 400 with query validation error
- Worker cold start or Cloudflare edge outage — transient 5xx error
