## 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-revalue-amount-050cf732 -d '<json body>'
```

Example prompt: Revalue an amount of 1000 from a source FX rate of 1.0 to a target FX rate of 1.1 and tell me the resulting value.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use FX revaluation computation without setting up a full financial data service or currency conversion API. It is ideal for agents that occasionally need to revalue notional amounts between two known FX rates and want verifiable, exact-price delivery with no signup overhead.

## Known failure modes

- Missing required fields (amount, rate_to, rate_from) result in a validation error
- Division by zero or zero source rate causes computation failure
- Non-numeric values for amount or rates return a parsing error
- Payment not received (x402 flow) results in a 402 response requiring USDC payment on Base or Solana

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object with schema 'delx/util-fx-revalue-amount/v1' and a 'revalued_amount' field containing the computed result of applying the target FX rate relative to the source rate on the given notional amount.
