> Delx Commerce FX Amount Converter is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-fx-amount-converter-ff956d89 -d '<json body>'
```

Example prompt: Convert 100 USD to BRL using an exchange rate of 5.2 — multiply the amount by the rate and give me the result in 6-decimal precision.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
