Are there typed SDKs available?

Yes. First-party TypeScript, Python and Go SDKs ship from the same OpenAPI spec as the REST docs, so every endpoint is type-safe out of the box. Generators for Java and C# are on the public roadmap.

How are webhook payloads signed?

Every event carries an HMAC-SHA256 signature in the X-TKOS-Signature header keyed off your endpoint secret. We retry on 5xx and surface delivery history in the partner portal for 30 days.

What is the rate limit on the REST API?

Default partner accounts get 100 requests per second per API key with burst headroom. X-RateLimit headers ship on every response. Higher limits are available on request without re-quoting.

Where is the data hosted?

Primary region is Johannesburg with regional failover. POPIA-aligned controls, ICASA licensing, and per-tenant encryption keys. BAA available for healthcare workloads on request.

Do you have a sandbox?

Yes — trial keys unlock a sandbox tenant with virtual DIDs, simulated CDRs and a mocked AI receptionist so you can integrate end-to-end without paying for minutes.

What's inside

Three layers, one tier-1 carrier.

Every TKOS integration runs across the same three layers — voice routing on the carrier edge, AI inference on the platform, and data residency anchored in Johannesburg. The wholesale voice fabric is what makes the rest cheap to run.

Voice routing

500+ direct carrier interconnects
Africa-direct least-cost routing
STIR/SHAKEN attestation on egress

AI inference

Sub-second response on Ava receptionist
Streaming transcripts over webhooks
Bring-your-own prompts & escalation

Data residency

Johannesburg-anchored primary region
POPIA-aligned, ICASA-licensed
Per-tenant encryption & audit logs
