All FX pairs, forex cross rates

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

All FX pairs in one call: cross rates for every pair among the major currencies (USD, EUR, GBP, JPY, CHF, CAD, AUD, CNY) or up to 12 chosen ones, from the European Central Bank's daily reference rates, with the date they apply to. Use to fill a forex rate table, convert between many currencies at once, or check a cross rate. Reference mid rates, not live bid/ask.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/fx/all?currencies=USD%2CEUR%2CGBP"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/fx/all?currencies=USD%2CEUR%2CGBP&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
