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 with the base currency (EUR), snapshot date, previous business day date, a staleness boolean, the source name and URL, fetchedAt timestamp, business days old count, a rates map of currency codes to float values, and a changeVsPrevPct map of day-over-day percentage changes for each currency.
Example use cases

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/eu/fx?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need official, ECB-published euro reference rates with a staleness indicator and day-over-day change data, particularly for compliance, invoicing, or financial reporting use cases. Choose over third-party FX APIs when ECB provenance and the specific currency subset (EUR base, CHF/GBP/JPY/PLN/USD) are sufficient.
Side effects
- ECB does not publish rates on weekends or non-TARGET working days — stale flag will be true
- Rate data may be delayed if ECB has not yet published the 16:00 CET update — businessDaysOld > 0
- Network or upstream ECB feed failure may result in a 5xx error
- Only a limited set of major currency pairs (CHF, GBP, JPY, PLN, USD) are included; exotic pairs are not available
