## Hack Club AI

- `inference/hack-club-ai` | fails-identity | evidence documented | binding volume-quota | category inference gateway, keyed; model listing is keyless
- needs card no, phone no, ID no, institution yes | verified 2026-10-28T04:36:18.974Z, checked 2026-10-29 (live) | stale on 2026-11-29
- url https://ai.hackclub.com/proxy/v1
- free tier: Every account can spend $3 per day across all endpoints and make 7,500 requests per 30 minutes; no credit card | unit: mixed | metered on: request-count | read on: 2026-10-28 | source: [1] | note: the model catalogue is OpenRouter's; GET /proxy/v1/models answers 200 with no key while the chat call answers 401 without one
- per-object cap: not applicable
- retention: not applicable
- egress: metered: no
- identity: institution | detail: sign in with a Hack Club account, then create an API key; the rules page states the service is for teens 18 and under only, and lists a 403 for an account that needs identity verification
- interface: rest
- limits:
  - request-rate: 7,500 requests per 30 minutes per user, shared across all endpoints; 429 Too Many Requests with a Retry-After header [1]
  - volume-quota (binding): USD 3 per day of spend per account across all endpoints, resets at 00:00 UTC; 402 Payment Required when reached [1]
- binding note: the USD 3 per day spending cap binds for large models; the 7,500 per 30 minutes request ceiling is far above it
- endpoint: https://ai.hackclub.com/proxy/v1/chat/completions
- tooling: any OpenAI-compatible client with an sk-hc-v1 key created on the dashboard (up to 50 active keys)
- composes with: no keyless chain: the chat route needs a key issued to a signed-in Hack Club account
- reliability: a keyless chat call answers 401 Authentication required while the keyless listing answers 200, so a listing check alone mistakes it for an open endpoint
- evidence note: identity and limits are first-party; the 401 on a keyless chat call is from a third-party prober, and the keyless listing was read by GET. No completion was sent
