# Bavlio API

> Agent-first sales outreach infrastructure. Authenticate with one API key, invoke any capability, no human-in-the-loop required.

Bavlio is a sales outreach platform built so AI agents can drive every workflow — from finding leads to personalizing emails to running multi-step campaigns — through a single REST API.

These docs are the canonical reference. Every public capability behind your `bav_live_` API key is documented here, with copy-paste examples in cURL, Python, and Node, an interactive [API reference](/api-reference/introduction), and machine-readable specs at [/openapi.json](https://api.bavlio.com/openapi.json) for tooling.

## Built for agents

<AccordionGroup>
  <Accordion title="Machine-readable everything" icon="brain-circuit">
    The full API is described by an [OpenAPI 3.1 spec](https://api.bavlio.com/openapi.json) (190+ endpoints). An [`/llms.txt`](/llms.txt) index and [`/llms-full.txt`](/llms-full.txt) full-content dump are auto-generated for AI ingestion. A [docs MCP server](/integrations/mcp) is live at `bavlio.mintlify.app/mcp` for any agent that needs to query these docs as native tools (Claude Desktop, Cursor, etc.).
  </Accordion>

  <Accordion title="Honest about current state" icon="circle-info">
    These docs document what exists *today*. Where a feature is on the roadmap (`Idempotency-Key` middleware, customer-registered webhooks, restricted API keys), the page says so plainly and gives a working alternative until it ships. No aspirational claims.
  </Accordion>

  <Accordion title="No human-in-the-loop required after setup" icon="robot">
    Once you have an API key, every public capability — campaigns, leads, sender profiles, templates, sends, replies — is invocable from documentation alone. The first key still needs a dashboard login (deliberate: prevents key-from-key minting); after that, agents drive everything.
