How this service works
Inventory supplied robots.txt groups, literal rule strings and sitemap declarations; no fetching or permission evaluation.
Output
A structured inventory of the supplied robots.txt text, including all user-agent group names, the literal allow/disallow rule strings under each group, and any sitemap URL declarations present in the file. No URL fetching or permission evaluation is performed.
Example use cases
Audit site crawl rules for SEO
“I have this robots.txt text from a client's site — can you break down all the user-agent groups, their exact allow and disallow rules, and any sitemap URLs declared in it so I can audit their SEO crawl configuration?”
Inventory competitor robots directives
“Here's a robots.txt file I copied from a competitor's site. Can you list every user-agent group and all the literal rule strings in it, plus any sitemap declarations, without making any web requests?”
Validate robots.txt structure before deployment
“Before I deploy this robots.txt, can you parse it and give me a full inventory of all the user-agent groups, disallow and allow rules, and sitemap entries so I can verify everything looks right?”
Technical details
Endpoint
POSThttps://penny-army-reference-mainnet.spruceboundgranitestudio.workers.dev/v1/probes/robots-directives-inspect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to statically parse and inventory the contents of a robots.txt file you already have as text — specifically to enumerate user-agent groups, extract literal rule strings, and list sitemap declarations — without any live URL fetching, permission evaluation, or crawlability checks. Prefer alternatives if you need to evaluate whether a specific URL is allowed for a given bot, or if you need to retrieve a robots.txt from a live server.
Side effects

- Malformed or empty robots.txt text — may return empty or partial inventory
- Non-robots.txt text supplied — output may be empty or nonsensical
- Missing 'text' field in request body — validation error
