The Kleos API

Sell Kleos under your own name. Your customers get the entire platform — research, calls, objection handling, booked appointments — and they never see ours.

What you get

A customer you create through this API is a full Kleos account, not a stripped-down copy. The same research, the same compliance gates, the same certification a direct Kleos customer gets. Nothing was built twice, which is also why nothing here can wave a customer past a gate: if Kleos would not make a call for its own customer, it will not make it for yours either.

You keep the relationship, the branding and the invoice. Kleos is your supplier and stays invisible — no provider names appear anywhere in this API, in the emails sent on your behalf, or in anything your customers see.

The shape of an integration

Create a customer for each business you are running calls for.
Ask for their readiness — Kleos tells you exactly what is still in the way, in codes you can render as a checklist.
Clear the blockers, then place calls and read outcomes.

Everything above works in test mode from your first minute, before any commercial conversation is finished. Test mode is not a sandbox with fake endpoints; it is the same API writing real records, with every side effect — dialling, provisioning, spending — switched off.

Nothing dials by accident. Creating a customer buys no number, publishes no agent and places no call. Every one of those is a separate, individually gated step.

Requests are JSON in, JSON out, over HTTPS only. Every response carries an x-kleos-request-id header and an x-kleos-mode header saying whether it was handled as test or live.
