x402 APIPassing, checked 4 h ago

Convert between 30+ currencies at the European Central Bank's daily reference rate, for today or any past date. Returns the converted amount, the per-unit rate and the date the rate is actually from — the ECB publishes on business days only, so a weekend date answers with the previous business day and says so instead of pretending. Reference rates for accounting and reporting, not tradable quotes.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://402.com.tr/api/x402/fx-convert?amount=100&date=2026-07-24&from=USD&to=EUR%2CTRY'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://402.com.tr/api/x402/fx-convert?amount=100&date=2026-07-24&from=USD&to=EUR%2CTRY' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
