## How to call it through Zero

```sh
zero fetch --capability stablecoin-payment-provider-detail-lookup-c9ec42e6
```

Example prompt: Can you pull up the full provider details for Circle — specifically which stablecoins they support and where they can on-ramp or off-ramp funds?

## When to prefer this

Use this endpoint when you need structured, cited, and dated details about a specific stablecoin payment provider — including which stablecoins they support and in which corridors or countries. Prefer this over general web search when you need machine-readable, confidence-rated data that cites primary sources. Best used after a search_providers call to obtain a valid provider ID.

## Known failure modes

- Unknown or invalid provider ID returns an error or empty response
- Stale data if provider has updated its offerings since last retrieval
- Provider ID not found if querying before running search_providers to get valid IDs
- Network timeout from upstream Railway-hosted service
- Missing or incomplete corridor data for newer or less-documented providers

## How this service works

What exactly does this provider support, where is it licensed and what does it charge? Full cited record for one provider: stablecoin rails, corridors, licences, published fees, coverage, developer and agent-payment support. Every fact has source URL, retrieval date, quote and confidence.

## Output

A JSON object containing the provider's ID, name, supported stablecoin assets, confidence level of the data, source URL where the data was verified, and the date the data was retrieved. Example includes Circle supporting USDC and EURC with 'published' confidence citing circle.com.
