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.
Example use cases
Pre-crawl agent access check
“Before my agent scrapes techcrunch.com, can you check Agent Weather to see if it allows AI crawlers in its robots.txt and whether it has an llms.txt file?”
AI-friendliness audit for a partner site
“I need to audit whether stripe.com is publishing any AI-agent access signals — check its robots.txt named-agent groups, Content-Signal values, and any well-known JSON files it serves.”
Monitor domain policy drift
“Check Agent Weather for anthropic.com and tell me what changes have happened to its AI access policy in the last 7 days — I want to know if anything shifted in the robots.txt or llms.txt.”
Technical details
Endpoint
GEThttps://api.agentweather.io/v1/access-policy/:domain?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
