    title: 'Compass API',
    description: `
Compass is a free, open-source platform to help people form deep, meaningful, and lasting connections — whether platonic, romantic, or collaborative. Our API provides programmatic access to core platform features including user profiles, messaging, compatibility scoring, and community features.

## Access Tiers

### Tier 1 — Public Access (no authentication required)
Some endpoints are publicly accessible without authentication, such as events and server health. These are marked as **public** in the endpoint documentation.

### Tier 2 — User Access (Firebase authentication required)
Most endpoints require a valid Firebase JWT token. This gives you access to your own user data, profile, messages, and all interactive features.

  To obtain a token:

  **In your browser console while logged in (CTRL+SHIFT+C, then select the Console tab):**
\`\`\`js
const db = await new Promise((res, rej) => {
  const req = indexedDB.open('firebaseLocalStorageDb')
  req.onsuccess = () => res(req.result)
  req.onerror = rej
})
const req = db.transaction('firebaseLocalStorage', 'readonly').objectStore('firebaseLocalStorage').getAll()
req.onsuccess = () => {
  const id_token = req.result[0].value.stsTokenManager.accessToken
  console.log('YOUR_FIREBASE_JWT_TOKEN is the string below:')
  console.log(id_token)
  copy(id_token)
}
\`\`\`

**For testing (REST):**
\`\`\`bash
curl 'https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=${apiKey}' \\
  -H 'Content-Type: application/json' \\
  --data '{"email":"you@example.com","password":"yourpassword","returnSecureToken":true}'
# Use the returned idToken as your Bearer token
\`\`\`

Tokens expire after **1 hour**. Refresh by calling \`getIdToken(true)\`.

Pass the token in the Authorization header for all authenticated requests:
\`\`\`
Authorization: Bearer YOUR_FIREBASE_JWT_TOKEN
\`\`\`

In the API docs, authenticate through the green button at the bottom right of this section.

**Don't have an account?** [Register on Compass](${DEPLOYED_WEB_URL}/register) to get started.

## Rate Limiting

API requests are subject to rate limiting to ensure fair usage and platform stability. Exceeding limits will result in a \`429 Too Many Requests\` response. Rate limits are applied per authenticated user. Unauthenticated requests are limited by IP.

## Versioning

This documentation reflects API version ${pkgVersion}. Endpoints marked as **deprecated** will include a \`Sunset\` header indicating when they will be removed, and a \`Link\` header pointing to the replacement endpoint. Breaking changes are avoided where possible.

## Error Handling

All API responses follow a consistent error format:
\`\`\`json
{
  "message": "Human-readable error description",
  "details": { /* Optional additional context */ }
}
\`\`\`

Common HTTP status codes:
- \`200\` Success
- \`400\` Bad Request — invalid or missing input
- \`401\` Unauthorized — missing or expired token
- \`403\` Forbidden — valid token but insufficient permissions
- \`404\` Not Found — resource does not exist
- \`429\` Too Many Requests — rate limit exceeded
- \`500\` Internal Server Error
