How this service works
GPTBot access decision fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
Output
Returns a structured result containing: the observation (what was found publicly), the threshold used for the criterion, a clear allow/block/unknown verdict, the exact URL of the evidence source (e.g. robots.txt), any limitations of the passive check, and a mode-specific recommended action. No login, payload injection, or active testing is performed.
Example use cases
Verify own site allows GPTBot
“Is GPTBot allowed to crawl my site at https://myblog.com? Pull the current robots.txt and tell me the verdict, what rule applies, and whether there are any issues I should know about.”
Audit competitor GPTBot policy
“Can you check if GPTBot is blocked on https://competitorsite.com? I want to see the evidence from their public robots.txt and a clear allow or block verdict.”
Monitor GPTBot access change over time
“Compare the current GPTBot access rules on https://newspublisher.com against this baseline I got last week — has anything changed, and what's the latest verdict?”
Technical details
Endpoint
POSThttps://agentreadiness.halowerk.com/v1/gptbot-access-decision?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, passive, read-only check of whether GPTBot is permitted to crawl a specific public URL or domain. It is ideal for site owners auditing their own crawler policy, researchers comparing competitor stances on AI crawlers, or monitoring pipelines that need a structured verdict with cited evidence. Prefer this over manual robots.txt inspection when you need a machine-readable verdict with threshold logic and a recommended action. Use the sibling GPTBot repair plan endpoint if you also want remediation steps.
Side effects
- Target URL is unreachable or returns non-200 status — verdict may be inconclusive
- robots.txt is absent or malformed — observation notes missing file, verdict uncertain
- Target uses wildcard or ambiguous directives that cannot be definitively resolved
- Supplied URL is private or behind authentication — passive check cannot retrieve evidence
- Rate limiting or network errors on the target prevent evidence retrieval
