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 developer-tool x402 services (up to the requested limit), each with service name, network, 30-day call count, price in USD, resource URL, and unique paying wallet count. The response also includes the total matched count, the query parameters used, a snapshot hash for verification, the scoring revision, and a generation timestamp.
Example use cases
Scouting popular dev-tool APIs

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-developer-tools?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need ranked discovery of x402 services in the developer-tools category, with rankings grounded in real 30-day on-chain usage (calls and unique paying wallets). Prefer this over generic API directories when you need verifiable, usage-weighted rankings with cryptographic snapshot receipts for auditability. Use this instead of the broader market index when you want to filter specifically to developer tooling rather than the entire x402 market.
Side effects
- No matching services found for the developer-tools tag — returns empty list with count 0
- Snapshot data stale or unavailable — may return older scoring revision
- Malformed query parameters — returns 4xx error
- Worker cold-start or Cloudflare edge failure — returns 5xx or timeout
- Payment not included — returns 402 Payment Required
