Documentation

Everything the agent knows, written down.

Guides for briefing an agent, a reference for every connector, and the full REST and webhook API. Written by the people who build it, updated the day it ships.

Quickstart

One call creates an agent, points it at a source and hands it a policy. It reads your transcripts before it answers anything, so the first draft already sounds like your team.

Sandbox keys, no card, no call

Every response is replayable

Rehearse on real calls before going live

  -H "Authorization: Bearer $SERMO_KEY" \
  -d source=zendesk \
  -d channel=voice+chat \
  -d policy

Start anywhere, nothing assumes the rest.

Each section stands on its own. If a page needs something from another, it links to it rather than assuming you read it.

Getting started

Connect a source, point Sermo at your transcripts and have a working agent answering by the afternoon.

Changelog

Every release, what changed, and whether you need to do anything about it.

Updated weekly

For developers

An API you can plan around.

The contract is the product. If we cannot keep an endpoint stable we version it rather than quietly changing what it returns.

Typed and versioned

Every endpoint is versioned in the path and never changes shape underneath you. Deprecations get twelve months and a migration note.

Sandbox from day one

Sandbox keys issue instantly and behave exactly like production, against synthetic transcripts you can reset whenever.

A changelog worth reading

Every release says what changed and whether it needs anything from you. Subscribe by RSS or webhook.

Developer channel

A shared channel with the engineers who build Sermo, not a ticket queue. Most questions get an answer the same working day.

Request an invite

Status and incidents

Live availability per region and per connector, with a written post-mortem on anything that lasted longer than five minutes.

All systems operational
