Hack Club AI

Appearance

Exa ​

Use Exa through the Hack Club AI proxy to search the web, find similar pages, extract content from URLs and answer questions with live web context.

Closed beta

Exa access currently requires the enable_exa feature flag. DM @mahad on Slack if you need access.

Endpoints ​

POST /proxy/v1/exa/search
POST /proxy/v1/exa/findSimilar
POST /proxy/v1/exa/contents
POST /proxy/v1/exa/answer

These endpoints proxy Exa's API. Send the same JSON body you would send to Exa, but authenticate with your Hack Club AI API key instead of an Exa API key.

Authentication ​

bash
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

Search the web for pages matching a query.

bash
curl https://ai.hackclub.com/proxy/v1/exa/search \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "Hack Club projects",
    "numResults": 5
  }'

Find Similar ​

Find pages similar to a given URL.

bash
curl https://ai.hackclub.com/proxy/v1/exa/findSimilar \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://hackclub.com/",
    "numResults": 5
  }'

Contents ​

Extract page contents from URLs.

bash
curl https://ai.hackclub.com/proxy/v1/exa/contents \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "urls": ["https://hackclub.com/"]
  }'

Answer ​

Ask a question and get an answer grounded in web results.

bash
curl https://ai.hackclub.com/proxy/v1/exa/answer \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "What is Hack Club?"
  }'

Streaming Answers ​

If Exa supports streaming for your request, pass "stream": true and read the response as server-sent events.

bash
curl https://ai.hackclub.com/proxy/v1/exa/answer \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "What is Hack Club?",
    "stream": true
  }'

Billing ​

Exa usage counts toward your normal Hack Club AI daily spending limit. The proxy records Exa's costDollars.total value for each request.
