Anjal LinkedIn — Signals API is one of 17 APIs that [Anjal](https://apis.io/providers/anjal-app/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 6 JSON Schema definitions. Tagged areas include LinkedIn — Signals. The published artifact set on APIs.io includes an OpenAPI specification and 6 JSON Schemas.

Deterministic real-time intent watchers. Every signal is a keyword plus a plain-English firing rule (e.g. "Flag as ready when the author is a founder complaining about cold email — skip vendors and agencies"). Two-pass classifier: 1. Triage — text-only LLM scores each post 0–100; obvious rejects drop without paying any LinkedIn quota. 2. Verify — survivors get a profile lookup (cached, multi-session routed) and the full classifier runs with the author's role + company as authoritative context. The firing rule decides engage/intent, the reason cites evidence from the post. Sessions auto-distribute — by default polling spreads across all healthy LinkedIn sessions for the tenant, multiplying daily throughput by the number of connected accounts. Pass a specific sessionId on the create body to pin instead. Optional HMAC-signed webhook delivery with automatic retries. Auditable end-to-end.
