## 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 x402-provider-dossier-baf88a7a -d '<json body>'
```

Example prompt: Can you pull a full dossier on the x402 provider at api.example.com — I want to see their market context, reputation, and what others know about them before I start autopaying their endpoints?

## When to prefer this

Use this endpoint when an agent needs deep background on a specific x402 provider before deciding to autopay their resources, or when a user wants to research a seller's reputation and market context in the x402 ecosystem. Prefer over general web search when you need structured, x402-specific intelligence aggregated from actual transaction and observation data.

## Known failure modes

- Unknown provider returns empty or null dossier
- Provider identifier not found in the x402 index returns 404 or empty result
- Malformed provider input causes 400 validation error
- Payment not received causes 402 response requiring x402 payment
- Upstream data source unavailable causes 503 or degraded response
