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 count of returned services (up to 25 by default), the query parameters used (ranking by payers, tag=perps), total matched services, and an array of ranked services each with name, network (EVM chain ID), 30-day call count, price in USD, resource URL, and 30-day unique paying wallets. Also includes a 'declaredBy' field, snapshot generation timestamp, and a receipt with snapshot hash and scoring revision for auditability.
Example use cases
Scouting perp data APIs for a trading bot
“I'm building an automated perp trading bot and need to know which x402 perps APIs are actually getting real usage — show me the top ones ranked by paying wallets in the last 30 days.”
Evaluating perp market competition
“Can you pull the x402 Bazaar leaderboard for perpetuals services and tell me how many active services there are, what they charge, and which ones are dominating by call volume?”
DeFi integration partner research
“I'm evaluating which perpetuals data feed APIs on the x402 network would be worth integrating — find me the top-ranked ones by unique paying wallets so I can see which have real traction.”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-perps?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to discover or rank perpetuals/perps-tagged x402 pay-per-call services by real 30-day usage metrics (paying wallets and call volume). It is the right choice over generic web search when you need verifiable on-chain usage signals rather than self-reported API directories, and when you want a cryptographically receipted snapshot for auditability. Prefer sibling endpoints for other tags (solana, options, leverage, usdc).
Side effects
- No services tagged 'perps' indexed yet — returns empty services array with count 0
- Snapshot stale or worker cold-start — may return slightly outdated ranking data
- Rate limiting or payment failure — 402 response if USDC payment not accepted
- Malformed response if the underlying index is being rebuilt
