Authentication & Security 2

Stack Exchange Users API declares 2 security schemes for authenticating requests. It supports OAuth 2.0 (oauth2) using the authorizationCode flow, exposing 4 scopes. An API key is passed in the query as key (apiKey). By default, every request must be authenticated.

  • oauth2 — OAuth 2.0 explicit or implicit flow. Apps register on stackapps.com. Read methods do not require auth; write methods require writeaccess. privateinfo is needed…
  • apiKey — Optional app key. Sending a key raises the daily quota from 300 to 10,000 requests per IP and is the recommended default for any non-trivial client.

Where this information came from

This is an independent, third-party profile of Stack Exchange Users API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
