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 list of up to 25 x402 services tagged 'legal', each with service name, network (e.g. eip155:8453), 30-day call count, 30-day unique payer count, price in USD, and resource URL. Also includes query metadata (route, total matched count, ranking criterion), the declarant type, and a generatedAt timestamp serving as a signed snapshot receipt.

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-legal?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover and rank x402-protocol services specifically in the legal domain based on real usage signals (calls and paying wallets) rather than self-reported metadata. Prefer it over general web search or registry lookups when you need verifiable, payment-backed popularity data with a snapshot receipt for auditability.
Side effects
- No services currently tagged 'legal' in the index returns an empty services array
- Stale snapshot if the index has not been updated recently
- HTTP 402 if the $0.008 USDC payment is not attached or fails
- Malformed response if the upstream worker is unavailable
- Score or count figures may reflect a lagging 30-day window rather than real-time data
