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 the route queried, total matched services, a capped list of ranked service entries (each with name, network, 30-day call count, price in USD, resource URL, and unique payers in 30 days), plus metadata including who declared the data, when the snapshot was generated, and a snapshot hash for auditability.

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-verification-deep?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need demand-signal-ranked discovery of verification-category services on the x402 network — particularly when you want to filter by real economic activity (paying wallets, call volume) rather than self-reported metadata. Prefer it over generic API directories when you specifically need x402-native, pay-per-call verification services with on-chain usage evidence.
Side effects
- No services indexed under the 'verification' tag — returns empty list with count 0
- Snapshot data is stale if the indexer has not recently crawled — generatedAt timestamp may be old
- Payment of $0.02 USDC not provided or rejected — 402 Payment Required response
- Upstream worker unavailable — 5xx error from Cloudflare Workers runtime
- Schema mismatch if query parameters are malformed — may return 400 or unexpected empty results
