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 (up to 25 by default) of x402 services tagged 'volatility', each with name, network, 30-day call count, USD price per call, resource URL, and 30-day unique payer count. Also includes query metadata (ranking method, limit, total matched count), the route used, a snapshot generation timestamp, and a declaration of who indexed the data.

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-volatility?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need discovery of x402 services tagged 'volatility', ranked by real 30-day paying-wallet activity. Prefer it over generic web search or static API directories when you need live usage signal (actual payers, call volume) rather than self-reported metrics, and when you want a verifiable snapshot receipt. Not suitable for L402, Tempo MPP, Olas, or other protocol registries — those are covered by separate /economy routes on this same service.
Side effects
- No services matched the 'volatility' tag — returns empty services array with count:0
- Upstream x402 index unavailable — may return HTTP 5xx or stale snapshot
- Snapshot hash or scoring revision missing if index is mid-refresh
- Network or Cloudflare Worker timeout for slow index scans
