Automated access

Respectful, robots-compliant retrieval of public HTML is allowed. This access statement is not a licence to reuse third-party source data.

Last updated 15 August 2026

Public HTML

  • Follow robots.txt and use the published sitemap index for discovery.
  • Identify the client with a truthful user agent and contact URL or email.
  • Cache responses, honor ETag and Last-Modified validators, and avoid repeatedly fetching unchanged pages.
  • Use modest concurrency, back off on 429 or 5xx responses and respect Retry-After.
  • Do not bypass authentication, CAPTCHA, private routes, rate limits or other access controls.

Preferred representation

Cutoff facts are available in server-rendered semantic HTML without JavaScript. Tables include captions, scoped headers, stable data-field attributes and a release identifier. The interactive API is not offered as a public bulk mirror and may change or be restricted.

Rights remain separate

Permission to fetch public HTML does not grant copyright, database, trademark or other reuse rights in JoSAA, CSAB, institutional or third-party material. Review the source and licensing status before reuse.
