SignalsAPI — Append-only hiring-events ledger exposed as an 'agent data plane': every observation of a requisition on a company's ATS or job board is written as an event rather than overwriting a row — three event types (opened = never-seen-before requisition, reposted = same requisition reappearing after a gap, reobserved = still present). No silent mutations, so the history stays intact and replayable. On top of the ledger: six derived primitives — hiring pulse (accelerating/decelerating/surging per company), first hire (when a company opened its first-ever role in a function, i.e. a new bu…

Append-only hiring-events ledger exposed as an 'agent data plane': every observation of a requisition on a company's ATS or job board is written as an event rather than overwriting a row — three event types (opened = never-seen-before requisition, reposted = same requisition reappearing after a gap, reobserved = still present). No silent mutations, so the history stays intact and replayable. On top of the ledger: six derived primitives — hiring pulse (accelerating/decelerating/surging per company), first hire (when a company opened its first-ever role in a function, i.e. a new budget line), repost pain (roles a company has failed to fill, ranked by repost frequency), ATS migrations (applicant-tracking vendor switches with dates), role demand (market-wide role/geography demand over time), and a change feed with a replayable cursor. Every read carries an as_of timestamp; history-backed reads carry per-value provenance (board, observation time, confidence), and freshness is machine-advertised via X-Data-Freshness and X-Meter-Class headers. Access via REST /v1, an MCP server exposing the same primitives as agent tools, and a Clay HTTP provider for enrichment columns.

SignalsAPI offers (Alternative, Sentiment) — Not published — request confirmation. Scale signals: continuous observation across multiple ATS platforms (examples name Greenhouse and Lever boards), events written per observation across the covered universe, live ingestion at 'new roles within 15 minutes'. The public Signal Explorer (jobs.signalsapi.com) exposes the covered postings for sizing..
The product's own use is sales-intelligence for recruiters/agencies (signal-to-decision-maker matching, €79/mo Starter, contact verification add-ons). The underlying ledger extends to: hiring-momentum alpha (pulse series per company), expansion/new-entity detection (a first Berlin-entity posting cluster is a DACH entry signal), ATS-vendor sales targeting via migration events, labour-market role-demand indices for consulting and public policy, and training data for models predicting role difficulty or company growth. For AI-agent workflows, the change feed with replayable cursor is a designed-for agents data-consumption pattern most job-data vendors don't offer.
The data is with 2 years of history.
Coverage spans US, UK; Application Software, Human Capital & Employment Services; alternative, sentiment; equities.
