Example prompt: Can you audit this FX quote for me — I'm sending 1000 GBP and was quoted 1145 EUR with a fee of 8.50? I want to know if the rate and fee look fair.

## When to prefer this

Use this endpoint when you need a lightweight, per-transaction audit of an FX quote before committing to a currency conversion — particularly useful in agentic payment workflows, remittance pipelines, or compliance checks where you want to verify that a quoted rate, fee, and target amount are internally consistent and not misleading. At $0.01 per call it is cost-effective for high-frequency screening.

## Known failure modes

- Missing required fields (sourceAmount, sourceCurrency, targetCurrency) return validation errors
- Unsupported or invalid 3-letter currency codes cause rejection
- sourceAmount of zero or negative is rejected by schema
- Network or service availability issues may return 5xx errors
- Ambiguous or unrealistic quote values may return inconclusive audit results
