Notyfi

Notyfi is a natural-language monitoring and notification service built by Perceptron ML (Y Combinator). Describe what to watch in one sentence -- new lawsuits, layoffs, price drops, listings, RFPs, breaking news -- and Notyfi watches the news, filings, databases, and the open web for it, delivering deduplicated canonical events instantly, hourly, daily, or weekly by email, on a live dashboard, or into agents and workflows via a REST API and a hosted MCP server. The API exposes persistent trackers, their event feeds, HMAC-signed outgoing webhooks, API-key management, account, and Stripe-backed billing. Authenticate with a Notyfi API key (Authorization: Bearer notyfi_mk_... or X-Api-Key).

Notyfi publishes 5 APIs on the APIs.io network, including account API, billing API, keys API, and 2 more. Tagged areas include Company, Notifications, Monitoring, Webhooks, and Real Time.

The Notyfi catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Notyfi’s developer surface includes documentation, API reference, pricing, signup flow, authentication, and 15 more developer resources.
