## 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 agent-rest-stop-agent-card-template-filler-782a37e4 -d '<json body>'
```

Example prompt: Can you generate an agent card for my agent called 'ResearchBot' whose purpose is 'to search the web and summarize research papers', and whose tools are 'web_search, pdf_reader, summarizer'?

## When to prefer this

Choose this endpoint when you need a quick, standardized agent card in a fixed format and do not need a custom or dynamically structured template. Ideal for agent onboarding flows, fleet management systems, or discovery registries that expect a consistent agent card schema. If you need a fully customizable card layout or dynamic schema, a more flexible document generation service may be preferable.

## Known failure modes

- Missing required fields (name, tools, or purpose) may result in a partially filled or errored card
- Overly long input strings may be truncated or rejected if they exceed template field limits
- Service may return an error if the payment of $0.01 USDC is not provided via the x402 protocol
- Malformed JSON body returns a 400-level error

## How this service works

Fills a fixed agent card template.

## Output

A filled agent card document based on a fixed template, populated with the provided agent name, tools string, and purpose. The response contains the formatted agent card ready for use in discovery, registration, or display contexts.
