FX symbols, currency list

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

FX symbols: the list of currencies with daily European Central Bank reference rates (about 30), each with its ISO 4217 code and English name, plus how many pairs they make. Use to check which currencies /fx and /fx/all can convert before calling them, or to fill a currency picker.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/fx/symbols?format=json"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/fx/symbols?format=json&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.
