How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with ok:true, the base and quote currency codes, the rate and side used, the original amount, the converted amount as a number, a decimals field (6), and a schema identifier string. The caller supplies the rate; this endpoint does not fetch live FX data.
Example use cases
Invoice amount in local currency
“I need to bill a Brazilian client 500 USD — convert that to BRL using a rate of 5.18, multiplying the amount, so I can put the right number on the invoice.”
Reverse-calculate base currency amount
“A European supplier quoted me €420 for an order. The EUR/USD rate is 1.08 — divide 420 EUR by that rate to tell me what I owe in USD.”
Agent wallet cross-currency payment check
“My agent holds USDC and needs to pay a merchant in JPY. The rate is 154.3 — multiply 200 USDC by that rate and show me how many JPY that equals.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/fx-convert-amount?utm_source=zero.xyzWhen to prefer
Use this endpoint when you already have an exchange rate from another source and simply need a reliable, verifiable computation to apply it to an amount. It is ideal for agentic workflows where rate fetching and amount conversion are decoupled steps, or when you need 6-decimal-precision output for financial record-keeping without the latency or cost of a live FX feed integration.
Side effects
- Missing required fields (base, quote, amount, rate, side) result in a validation error
- Invalid side value (anything other than 'multiply' or 'divide') may cause unexpected results
- Providing a rate of 0 would cause a division-by-zero error for the 'divide' side
- Non-integer amount values may be rejected or truncated
- Incorrect currency codes are accepted but not validated against real-world pairs
