## 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-llms-txt-template-filler-0817b783 -d '<json body>'
```

Example prompt: Generate an llms.txt file for my agent called 'PriceWatcher' — its purpose is to monitor product prices and alert users when they drop, and here are its relevant links: https://pricewatcher.dev, https://pricewatcher.dev/docs.

## When to prefer this

Use this endpoint when you need to programmatically generate a standards-compliant llms.txt file for an AI agent or tool, especially when automating agent registration or publishing metadata to directories. Prefer this over manual authoring when onboarding multiple agents or integrating llms.txt generation into a CI/CD pipeline.

## Known failure modes

- Missing required fields (name, links, or purpose) returns an error
- Malformed or empty links string may produce an incomplete llms.txt
- Payment not included or insufficient (requires $0.01 USDC via x402) results in 402 Payment Required
- Template rendering fails if input values contain unsupported characters or encoding issues

## How this service works

Fills an llms.txt template.

## Output

A filled llms.txt document containing the agent's name, purpose, and links formatted according to the llms.txt specification — ready to be hosted or submitted to an agent directory.
