$0.01 / callPaid per call · 0 free tier No signup

Reference fiat and stablecoin conversion rate from a static table, not a live feed. Returns rate and inverse; result carries a signed receipt.

Honest Scope Guarantee

Reference fiat/stablecoin conversion rates read from a static table compiled into the worker. Not a live feed, no as-of date, not a trading feed and not executable pricing; a pair outside the table is flagged known:false.

Quickstart & Execution

cURL (Paid-only route — unauthenticated calls return HTTP 402 Payment Required)

curl -X POST https://api.code402.dev/v1/tools/fx-spot-price-oracle/call \
  -H "content-type: application/json" \
  -d '{"base":"EUR","quote":"USD"}'

This route is paid-only (0 free calls/day); every unauthenticated request returns an HTTP 402 Payment Required challenge with its payment terms. Machines use USDC on Base; card credits (instant Stripe checkout) are enabled in this deployment. Signed XDR-1 receipts authenticate recorded service claims, not independent settlement, delivery or zero-knowledge proofs.
