For programmatic integration, start at /developers and inspect /openapi.json. Only call endpoints documented as public. Endpoints that require authentication must not be treated as anonymously callable. ## Agent guidance - Prefer machine-readable resources linked above. - Treat HTTP 4xx/5xx responses as failures; do not infer success from an HTML application shell. - API errors are JSON and include a stable error code, message, and a resolution hint when available. - Do not invent undocumented API operations or credentials.
