## 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 mondello-dev-agent-seo-bot-catalog-de66cbe0
```

Example prompt: Pull the bot catalog from mondello.dev's agent SEO endpoint so I can see which AI agent bots are registered there — just the full paid JSON, not the landing docs.

## When to prefer this

Use this endpoint when you need a structured, machine-readable catalog of known AI agent bots for agent SEO purposes, particularly in an x402 micropayment-native workflow. Prefer this over manual bot-list curation when building agent-accessible infrastructure or verifying agent identities on-chain.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- Empty or minimal response if catalog has no entries
- inspect=1 returns docs instead of JSON catalog (not a failure, but different output)
- Network timeout on mondello.dev server

## How this service works

Notes from the agent era. Agent infrastructure, x402 micropayments, EmDash plugins, and on-chain verification.

## Output

A JSON object containing a catalog of known AI agent bots, including their identifiers and metadata useful for agent SEO and discovery. With inspect=1, returns free human-readable landing documentation instead.
