Build on the agent.
Heard is a platform, not a black box. Use the API, MCP, webhooks and SDKs to embed the agent, ground it in your data, let it take real actions in your systems, and stream every conversation and event into your own stack.
What you can build
The primitives, all exposed
REST API
A clean, documented API to manage agents, knowledge, conversations and actions programmatically.
Learn moreMCP support
Expose your own tools to the agent over the Model Context Protocol — it discovers and calls them safely.
Webhooks
Subscribe to conversation, handoff and action events and drive your own workflows in real time.
SDKs
Typed client libraries so you ship integrations in hours, not weeks — with sensible defaults and retries.
Knowledge ingestion
Push documents and structured data programmatically and keep the agent’s knowledge in sync with your systems.
Custom actions
Register actions the agent may take — check an order, open a claim, book a slot — governed by your rules.
Built for real integration
Wire Heard into everything you run
Grounded retrieval
Every answer is retrieved from your knowledge and cited — inspect the sources behind any reply via the API.
Scoped keys & auth
Issue scoped API keys, control what each integration can touch, and rotate credentials without downtime.
Streaming & logs
Stream conversations and pull structured logs of every action for your own analytics and audit.
Multi-tenant ready
Model many brands or business units under one account, each with isolated knowledge and configuration.
Programmatic agents
Create, configure and version agents from code, so your infrastructure defines your support, not a dashboard.
Predictable contracts
Versioned, stable API surfaces and clear deprecation policy — build with confidence that it will keep working.
Why developers choose Heard
A platform that acts, not just a chatbot API.
- The agent takes real actions in your systems through the integrations you register — no glue-code puppetry.
- Native Arabic and English handled server-side, so your front end stays simple.
- Everything the dashboard does, the API does — no feature locked behind clicks.
- Idempotent, well-documented endpoints with webhooks for the events that matter.
