# Agent Weather Domain Access Policy Reader

> Agent Weather Domain Access Policy Reader is a paid API for AI agents from api.agentweather.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-29).

Fetches crawled access-policy readings for a single domain, including robots.txt AI-agent rules, llms.txt presence, Content-Signal values, and /.well-known JSON files

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-weather-domain-access-policy-reader-7b1de63e
```

Example prompt: What's the current AI-agent access policy for openai.com — does it have an llms.txt file, what do the robots.txt rules say for named AI-agent user-agents, and have there been any changes in the last 7 days?

## When to prefer this

Use this endpoint when you need a structured, pre-fetched snapshot of a specific domain's AI-agent and crawler access posture — including robots.txt named-agent rules, llms.txt, Content-Signal headers, and well-known files — without having to crawl and parse those files yourself. Prefer it over rolling your own crawl when you want historical 7-day change tracking alongside the current readings, or when you need a consistent, normalized format across many domains. It is ideal for pre-flight checks before an agent attempts to access a site, for compliance auditing, or for monitoring partner/competitor domains for policy changes.

## Known failure modes

- Domain not in tracked index — returns an error or empty result; use GET /v1/access-policy/index to find valid tracked domains
- Domain string malformed or missing — 400-level validation error
- Payment not completed — x402 payment required error returned before data is served
- Upstream crawl data stale or unavailable — readings array may be incomplete or missing recent signals
- Domain serves well-known files not as JSON — those files are skipped/unparsed per spec

## How this service works

Readings of the public files one tracked domain serves about crawler and agent access (GET /v1/access-policy/{domain}): robots.txt groups for named AI-agent user-agents and the * group, Content-Signal values, llms.txt presence and title, /.well-known JSON files (parsed only when served as JSON), se…

## Output

Returns a structured object containing: the domain name, generation timestamp, an array of access-policy readings (robots.txt groups for named AI-agent user-agents and the wildcard group, Content-Signal values, llms.txt presence and title, parsed /.well-known JSON files), and an array of change events observed over the prior 7 days.
