# Headless Jason AI SDR

> Sales Engagement API for AI Agents, by Reply.io. Headless Jason AI SDR is Reply.io's sales engagement platform packaged as an API for AI agents. It is not an app with a UI to automate — it is the API-first infrastructure an agent calls directly: search a 1B+ contact B2B database, manage contact data, run multichannel sequences (email + LinkedIn + calls), read and classify replies, flag meeting intent, and measure results including meetings booked (booking itself happens via Reply's in-app scheduler — there is no book-a-meeting endpoint today). Available integration surfaces: REST API, a live MCP server, the reply CLI (npm i -g reply-cli), and an installable agent skill (github.com/replyio/reply-skill). Sign up at https://run.reply.io/register (14-day free trial, no credit card required).

Everything listed here is callable today via the Reply.io API unless labeled "Coming soon" (specified, not yet callable) or "Concept" (future direction, no spec). Content last verified 2026-07-05.

## Flagship APIs

- [Prospect Search API](https://headless-jason-ai-sdr-7ajjk.ondigitalocean.app/apis/prospect-search.md): Search Reply Data — 1B+ contacts and 60M+ companies — by ICP filters like job title, seniority, department, industry, and location, and turn the matches into a prospect list. (Coming soon — Still marked Coming soon in Reply's API reference as of 2026-07-05 (targeted early July 2026) — check docs.reply.io for current status.)

- [Contact Enrichment API](https://headless-jason-ai-sdr-7ajjk.ondigitalocean.app/apis/contact-enrichment.md): Fill the gaps in a contact record — find missing emails and phone numbers, enrich by email or LinkedIn URL, and populate AI custom fields. (Coming soon — Still marked Coming soon in Reply's API reference as of 2026-07-05 (targeted late July 2026) — check docs.reply.io for current status.)

- [Outreach Actions API](https://headless-jason-ai-sdr-7ajjk.ondigitalocean.app/apis/outreach-actions.md): One-off sends outside a sequence — a single email, LinkedIn connection request, InMail, message, or voice message, on demand.
- [Conversations & Inbox API](https://headless-jason-ai-sdr-7ajjk.ondigitalocean.app/apis/conversations-inbox.md): The unified inbox as an API — read threads across email and LinkedIn, classify replies with categories, detect meeting intent, and respond. (AI draft-reply endpoints are marked coming soon in Reply's reference; everything else is callable today.)
- [AI SDR API (Jason)](https://headless-jason-ai-sdr-7ajjk.ondigitalocean.app/apis/ai-sdr.md): Program Jason, Reply's autonomous AI SDR — feed it knowledge bases, offers, and playbooks today; run full autopilot sequences with approval gates soon. (Knowledge bases, offers, and playbooks are callable today; autopilot sequences, pending approvals, insights, strategist, and web search are still marked coming soon in Reply's reference as of 2026-07-05 (targeted July 2026).)
- [Webhooks & Events API](https://headless-jason-ai-sdr-7ajjk.ondigitalocean.app/apis/webhooks-events.md): Outbound event subscriptions — Reply pushes every reply, open, click, bounce, and LinkedIn event to your endpoint instead of making you poll.
