Response Format

All responses return JSON with consistent structure:

{
  "ticker": "AAPL",
  "company_name": "Apple Inc.",
  "rating": { ... },
  "methodology_version": "2.0",
  "methodology_url": "https://alpha.ac/institute/methodology",
  "limitations_disclosure": "Alpha Governance Ratings are based on publicly available evidence and proprietary signal analysis. They represent Alpha's independent assessment and are not guarantees of future governance performance."
}

Every rating response includes methodology_url and limitations_disclosure for regulatory compliance.

Rate Limiting

Rate limits are enforced per API key per day. When exceeded:

{
  "error": "rate_limit_exceeded",
  "calls_today": 1001,
  "limit": 1000,
  "resets_at": "2026-04-05T00:00:00Z"
}

Caching

Responses include standard caching headers:

Cache-Control: public, max-age=3600
ETag: "abc123"

Rating data is refreshed on a rolling basis. Use If-None-Match headers to reduce bandwidth.

SDKs

Official SDKs are coming soon. In the meantime, the API follows RESTful conventions with JSON responses that work with any HTTP client.
