For Agents

List Gitter rooms a user belongs to, post and read chat messages, and inspect room membership using the v1 REST API.

Connect the Gitter API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Gitter API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Install Jentic One Beta (Self-Hosted)

Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

View OpenAPI Document

Jentic publishes the only available OpenAPI specification for Gitter API, keeping it validated and agent-ready. The Gitter API exposes a small set of operations against the Gitter chat platform — listing rooms a user belongs to, fetching room and user records, posting and reading chat messages, and listing the members of a room. Gitter has been migrated to Matrix, but the v1 REST API remains available for legacy chat integrations and bots. Authentication uses Bearer tokens issued from the Gitter developer settings.

Use Cases

Patterns agents use Gitter API for, with concrete tasks.

★ Build Notification Bot

Post CI build outcomes, deploy notifications, or release announcements into a Gitter room from an existing pipeline. POST /rooms/{roomId}/chatMessages accepts a single text body and returns the persisted message id, so the same bot can keep a sent-message log for later editing or audit.

Post the message 'Build #482 passed on main' into the room with id 5d3a4b... and return the new message id

Channel Activity Digest

Generate a daily digest of activity across the rooms a user belongs to. The agent calls GET /rooms to enumerate memberships, then pages GET /rooms/{roomId}/chatMessages with a sinceId per room to summarise new messages without re-fetching old ones.

List the user's rooms, then for each fetch chatMessages where sinceId is yesterday's last id and count messages by sender

Chat-Driven Support Bot

Run a support bot that watches a Gitter room and responds to questions. The bot polls GET /rooms/{roomId}/chatMessages, classifies each message, and posts a reply via POST /rooms/{roomId}/chatMessages — useful for legacy open-source projects still hosted on Gitter rather than Matrix.

Poll chatMessages for the project room, identify any message containing 'install', and reply with the documented install command

AI Agent Chat Replies

Use Jentic to let an AI agent post helpful replies into a Gitter room when triggered by an external event. The agent issues an intent like 'post a message to gitter', Jentic resolves POST /rooms/{roomId}/chatMessages, executes it with the Bearer token from the vault, and returns the message URL the user can verify.

Through Jentic, post the message 'Looking into this now' into the support room and return the response id

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Gitter Bearer tokens are stored encrypted in the Jentic vault (MAXsystem). Agents receive a scoped execution token — the raw token never enters the prompt or transcript, and a single rotation in the vault updates every caller.

Intent-based discovery

Agents search by intent (e.g. 'post a chat message') and Jentic returns the matching Gitter operation with its request schema, so the agent can call POST /rooms/{roomId}/chatMessages without reading docs.

Time to first call

Direct Gitter integration: half a day for token handling, room id resolution, and chat polling. Through Jentic: under 30 minutes — search, load, execute.

FAQs

Specific to using Gitter API through Jentic.

Why is there no official OpenAPI spec for Gitter API?

Gitter does not publish an OpenAPI specification — the platform has migrated to Matrix and the v1 REST docs are HTML only. Jentic generates and maintains this spec so that AI agents and developers can call Gitter API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Gitter API use?

Gitter uses Bearer token authentication. Tokens are issued from the Gitter developer settings page and sent as Authorization: Bearer <token>. Through Jentic the token is held in the MAXsystem vault and the raw secret never appears in the agent's prompt context.

Can I post a chat message with the Gitter API?

Yes. POST /rooms/{roomId}/chatMessages accepts a text body and returns the persisted message id, sender, and timestamp. Resolve the roomId first by listing GET /rooms or by calling GET /rooms/{roomId} with a known id.

What are the rate limits for the Gitter API?

Gitter applies a soft per-token cap roughly equivalent to 100 requests per minute per user, with stricter limits on message-posting endpoints to deter spam. There is no public counter; on HTTP 429 back off and retry after a few seconds before resending the request.

How do I list a user's rooms through Jentic with Gitter?

Search Jentic for 'list gitter rooms', load the GET /rooms schema, and execute against the stored Bearer token. The response is an array of room objects with id, name, uri, and userCount that you can iterate to drive a chat dashboard.

Is the Gitter API still supported now that Gitter is on Matrix?

Yes for the v1 REST API documented here — it remains live for legacy chat integrations against the Gitter rooms that have been bridged to Matrix. New projects often prefer the Matrix API directly, but the Gitter v1 surface is still functional for posting messages and reading rooms.
