VC Deal Flow Signal API is one of 4 APIs that [GitDealFlow](https://apis.io/providers/gitdealflow-com/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Signals, Startups, Deal Flow, Badges, and Search. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, rate-limit docs, and a changelog.

Free, no-auth REST API over the weekly startup engineering-acceleration panel: bulk signals (JSON/CSV/NDJSON), single-startup lookups, sector rankings, citation-ready Q&A retrieval, site search, Scout Score receipts, prediction markets, SVG badges, machine-readable pricing, changelog, methodology and glossary, plus versioned /api/v1 aliases. One paid deep-signal endpoint is metered per call by credit-pack bearer key or x402 USDC on Base.
