# DDG FX Rate Lookup

> DDG FX Rate Lookup is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

## 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 ddg-fx-rate-lookup-461c7be8 -d '<json body>'
```

Example prompt: What's the current exchange rate from USD to EUR? I need the live FX rate right now.

## When to prefer this

Choose this endpoint when your AI agent needs a programmatic, machine-payable FX rate lookup with no OAuth setup and pay-per-call economics via x402 USDC micropayments. Ideal for agents operating autonomously in agentic workflows that need to pay for data without a human-managed API key subscription. Best for low-volume or on-demand FX lookups where a $0.01/call cost is acceptable.

## Known failure modes

- Payment not received or invalid x402 payment header — endpoint returns 402 Payment Required
- Unsupported currency pair — may return an error or empty result
- Malformed request body — missing required fields returns 400 Bad Request
- Provider data unavailable — upstream FX data source may be temporarily unreachable
- Network timeout — if the upstream rate provider is slow, response may be delayed
