## 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 agenttoolbox-docs-pack-fetch-aa1c42af -d '<json body>'
```

Example prompt: Fetch the relevant sections from these two documentation pages — https://docs.example.com/api and https://docs.example.com/auth — that explain how authentication works, and give me up to 4000 characters of excerpts.

## When to prefer this

Choose this endpoint when an AI agent needs to retrieve and focus on relevant portions of documentation from known URLs based on a specific query, especially in agentic pipelines where paying per-call via x402/USDC micro-payments is acceptable and the agent needs targeted excerpts rather than full page content.

## Known failure modes

- URL unreachable or returns non-200 — excerpt for that URL may be empty or error noted
- Query too short (under 2 chars) or too long (over 120 chars) — validation error returned
- More than 5 URLs submitted — schema validation rejection
- max_excerpt_chars out of range (below 1000 or above 6000) — validation error
- Payment not processed via x402 — 402 Payment Required response before content is returned
- URL content is not parseable or is binary — empty excerpt returned

## How this service works

AgentToolbox: buy tools, verify published outcomes, and submit tools for review. HTTP, x402 and MCP instructions for agents.

## Output

A JSON response containing extracted text excerpts from the provided documentation URLs, filtered and trimmed to the specified maximum character length and most relevant to the submitted query.
