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 count of returned services, the query parameters used (by payers, top N, readability tag), the total number of matched services in the index, an array of ranked service entries each with name, network, 30-day call count, price in USD, resource URL, and 30-day unique paying wallets, plus metadata fields for who declared it and the snapshot generation timestamp.

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-readability?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need evidence-based discovery of readability-tagged x402 services backed by actual 30-day payment telemetry rather than self-declared listings. It is the right choice when you want a verifiable, auditable snapshot (hash + scoring revision) of the readability service market, as opposed to raw crawl data or unranked directories. Prefer it over generic API registries when the x402 payment protocol context matters.
Side effects
- No services indexed under the readability tag — returns empty services array with matched:0
- Snapshot index stale or unavailable — may return 402 or 503 if the worker is unreachable
- Payment not attached or USDC balance insufficient — returns HTTP 402 requiring x402 payment
- Malformed query parameters — may return 400 with error details
- Rate limiting on the Cloudflare Worker — returns 429
