## Which one, for what

### Vocily AI (D)

Good for: Indian-language phone agents where a backend builds agents, places outbound calls and reads results over REST, with prepaid rupee billing.

Ahead on:
- Schema & documentation, 90 against 73
- Agent ergonomics, 84 against 57
- Security & auth, 46 against 40
- Payments & pricing, 40 against 15
- Maintenance & community, 61 against 11

Watch for: No status page, incident history or SLA was found

### Vogent API (D)

Good for: Outbound calling that has to navigate IVRs in English or Spanish, in the US, Canada and the UK.

Ahead on:
- Reliability, 62 against 40

Also in its favour:
- No incidents deducted, where Vocily AI loses 5 points for them

Watch for: No public changelog and no release found since January 2026

## Verdicts

**Vocily AI.** The REST API is documented in detail for a product a few months old, with an OpenAPI 3.1 file, required idempotency keys on calls, a Retry-After header on 429 and signed webhooks. No status page, SLA, SDK or security programme was found, and two releases in September 2026 removed fields under `/v1` on the day they were announced.

**Vogent API.** IVR detection and navigation models for outbound calls. No public changelog and no release found since January 2026.

## Before you call either

### Vocily AI

1. Send a fresh UUID in `Idempotency-Key` on every `POST /v1/calls`. The API refuses the request without it
2. Pass a `from_number` the workspace holds. The shared Test Number returns 403 from the API
3. Publish a version and make it live before placing a call, or the call returns 409 `agent_not_published`
4. Branch on `detail.code`, falling back to the top-level `code`. A 429 body is flat, so read `Retry-After`
5. Read `currency` on every call and chat record. Costs are in rupees or dollars depending on the organisation

### Vogent API

1. Send an `idempotencyKey` on `POST /dials`, a reused key returns 409
2. Create a call with `callAgentId`, plus `toNumber` and `fromNumberId` for phone calls
3. Tell the model when to emit `<|transfer|>`, since transfers fire on that tag
4. Verify webhooks with the HMAC in `X-Elto-Signature`
5. Expect new dials to fail at the workspace's concurrent dial limit until calls end
