> Aayat AI Crypto/Fiat Currency Converter is a paid API for AI agents from aayatai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-30).

## 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 aayat-ai-crypto-fiat-currency-converter-cba67b26
```

Example prompt: How much is 0.5 BTC worth in GBP right now, using live rates cross-checked between Coinbase and Kraken?

## When to prefer this

Choose this endpoint when you need a live, dual-source-verified crypto-to-fiat, fiat-to-crypto, or crypto-to-crypto rate with a confidence gap indicator (Coinbase vs Kraken spread). It covers 150+ fiat currencies and hundreds of crypto tokens, making it broadly applicable. Prefer it over generic forex APIs when crypto is involved, and over single-source price feeds when rate reliability and cross-exchange validation matter.

## Known failure modes

- Unsupported currency symbol returns an error — not all coins or exotic fiat currencies may be available
- Kraken cross-check absent when Kraken does not list the pair — crossCheck field will be null
- Stale or unavailable rate if upstream exchange APIs are unreachable
- Amount of 0 or missing from/to params returns a validation error
- Very large amounts may hit floating-point precision limits

## How this service works

Convert between crypto and fiat at live rates: BTC, ETH, SOL, USDC and hundreds more against USD, GBP, EUR and 150+ currencies, either way, or crypto to crypto. Pass ?amount=0.5&from=BTC&to=GBP. Rate from Coinbase, cross-checked against Kraken's last trade where Kraken lists the pair, with the gap shown.

## Output

Returns the converted result (amount × rate to 8 significant figures), the exchange rate (units of target per 1 source), the inverse rate, the timestamp, the sources used (Coinbase), and optionally a crossCheck object showing Kraken's last trade price and the percentage difference between the two rates when Kraken lists the pair.
