## 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 agentstamp-gold-stamp-mint-94868a74 -d '<json body>'
```

Example prompt: Mint a gold trust stamp for my AI agent on AgentStamp — submit a POST certification request so my agent gets gold-tier certified in the decentralized agent ecosystem.

## When to prefer this

Use this endpoint when you need to formally certify an AI agent at the gold tier on AgentStamp's decentralized trust platform. Prefer this over lower-tier stamp endpoints when gold-level trust certification is specifically required, and over generic identity services when the target ecosystem is the AgentStamp agent registry.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not processed, resulting in 402 Payment Required
- Invalid body: missing required fields (type, bodyType, body, method) returns 400 Bad Request
- Method mismatch: sending GET instead of POST returns 405 Method Not Allowed
- Agent already certified: attempting to re-mint a stamp for an already gold-certified agent may return conflict or duplicate error
- Service unavailable: decentralized infrastructure downtime returns 503

## How this service works

AgentStamp is a decentralized certification platform for AI agents. Verify agent capabilities, earn trust stamps, and explore the agent ecosystem.

## Output

A confirmation that the gold stamp has been minted for the agent, including certification details such as a stamp ID, tier level (gold), and timestamp or on-chain reference for the trust credential.
