How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
A JSON object containing the detected kind of identifier (e.g. 'isbn'), the original input string, a boolean valid flag, the normalized ISBN-13 representation, and the compact (no-hyphen) form of the identifier.
Example use cases
Book catalog ISBN validation
“Before I add this book to my catalog, can you check if 0306406152 is a valid ISBN and return its proper ISBN-13 format?”
User-submitted identifier QA
“A user just submitted the identifier 9780140449136 on our form — can you verify it's a valid ISBN and tell me what kind it is?”
Library data normalization
“I have a list starting with 978-0-7432-7356-5 — can you parse this ISBN, confirm it's valid, and give me the compact version without dashes?”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/id-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, fast, per-identifier validation and normalization for ISBN codes or similar structured identifiers, especially when you want to confirm validity and retrieve the canonical ISBN-13 and compact forms in a single call. Prefer it over manual regex checks or library-based validation when you need a hosted, pay-per-call microservice with no setup.
Side effects
- Invalid or unrecognizable identifier returns valid: false with no normalized output
- Missing required input query parameter causes a 400 or error response
- Non-ISBN identifiers may return an unknown kind or invalid result
- Malformed request (wrong method or missing params) may return an error
