## 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 stablecoin-profile-lookup-via-x402-micropayment-cc8343ce
```

Example prompt: Can you look up the stablecoin profile for USDC on the Ethereum chain and give me its current rates and metadata?

## When to prefer this

Use this endpoint when you need to look up structured profile data for a specific stablecoin by ticker (e.g. USDC, DAI), DefiLlama ID, or contract address on a given chain, especially in contexts requiring rates or compliance verification. Prefer this over generic token APIs when you need OFAC-screening-aware stablecoin data accessible via x402 micropayment rather than subscription-based APIs.

## Known failure modes

- Unknown or unsupported stablecoin symbol returns empty or error result
- Invalid contract address format causes a failed lookup
- Unsupported chain value returns no data
- Payment not completed results in 402 response before data is returned
- Mismatched chain and address pair yields no result

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object with a 'result' field containing the stablecoin's profile data (including rates, token metadata, and compliance-relevant information) and a 'success' boolean indicating whether the lookup succeeded.
