Connecting LLM agents to external APIs has historically required fragile manual prompt engineering and error-prone JSON parsing. Snowline resolves this by providing a fully compliant OpenAPI 3.1.0 specification at `/api/openapi.json`.
Modern agent frameworks can consume Snowline's OpenAPI schema directly, automatically generating typed tool definitions with strict input validation.
Snowline API endpoints adhere to RFC 9457 Problem Details error formats and return standard `RateLimit-Limit`, `RateLimit-Remaining`, and `Retry-After` headers.
This enables autonomous agents to handle rate limits gracefully and recover from edge cases without throwing unhandled exceptions.
