Warmly

Warmly is a signal-based revenue orchestration and AI go-to-market platform that de-anonymizes website visitors down to the individual person, unifies first-, second-, and third-party intent signals in a unified Context Graph, and runs two autonomous agents — an Inbound Agent that converts on-site visitors through AI chat and an outbound TAM Agent that orchestrates prospecting across email, LinkedIn, and ads. Warmly exposes a REST API and a hosted, OAuth-authenticated MCP server (both live at opps-api.getwarmly.com) that let agents list warm visitors and accounts, look up third-party intent signals, check credit balances, and push identified contacts into HubSpot, Salesforce, and sequences — with outbound webhooks reporting agent-tool execution status and delivering intent signals to downstream automations.

Warmly publishes 1 API on the APIs.io network. Tagged areas include Company, Sales, Marketing, Intent Data, and Revenue Orchestration.

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

Warmly’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 16 more developer resources.
