# Vocily AI (slim)

> Vocily AI is a hosted voice-agent platform from Bengaluru for phone calls, WhatsApp and website voice and chat, aimed at Indian languages. Its REST API builds and publishes agents, places outbound calls and reads back transcripts, recordings and costs.

**D · 53.8/100 · rank #540 of 722 · #8 in Conversational voice agents · not agent-ready · confidence medium**


Assessment: 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.

## Facts

- Kind: HTTP API · vendor: Vocily AI Private Limited · category: Conversational voice agents · legal entity: VOCILY AI PRIVATE LIMITED · provenance 59/100
- Endpoint: `https://api.vocily.ai` (HTTP)
- Auth: API key · pricing: Pay per use · x402: no · licence: Proprietary service under Vocily's terms of service. No open-source code or published package was found
- Probe metrics: not measured yet (probes haven't run)
- Surface graded: The public REST API at https://api.vocily.ai/v1 (54 operations) with its webhooks. The dashboard, the WhatsApp tooling and batch campaigns are outside it
- Architecture: Pipeline of a transcriber, a language model and a voice, each chosen per agent, with an optional backup from a different provider for each stage. No speech-to-speech mode was found in the docs
- Models: Speech-to-text from Soniox, Deepgram (Nova 2, Nova 3, Flux) and Sarvam Saaras v4, the default. Nine language models from OpenAI, Google and Sarvam. Voices from Vocily's own engine, Smallest, Sarvam, Cartesia and ElevenLabs (https://vocily.ai/pricing)
- Languages: The docs list 12 Indic languages (Assamese, Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, Urdu), three English variants and eight others. The site says 17+ Indian languages with code-mixing
- Telephony: Your own Plivo or VoBiz account, or a number rented from Vocily at $5 or ₹499 a month. Indian numbers need a compliance filing. Inbound and outbound, with call transfer
- Tool calling: Built-in hold, end call, transfer and WhatsApp template tools, custom HTTP tools with saved credentials, Cal.com booking and knowledge bases. Custom tools are built in the dashboard, not through the API
- API coverage: Agents with drafts, versions, publish and make-live, calls, recordings, chats, knowledge bases, caller memory, post-call analysis, the website widget, catalogues of models, voices and languages, and text to speech
- Rate limits: 300 requests a minute per key. Ten concurrent calls per organisation, five outbound and five inbound, with usage in `X-Vocily-Concurrency-Limit` and `X-Vocily-Concurrency-Used` on every response
- Errors: JSON with a `detail.code` reason and a message, a published table of reason codes by status, and a 422 that lists every invalid field. Every response has an `X-Request-ID`
- Webhooks: Five `call.*` events per agent, signed with HMAC-SHA256, sent at least once with up to three attempts (0 s, 2 min, 15 min). Endpoints are set in the dashboard
- Free tier: ₹200 or $2 of credit once the owner's email is verified, no card. Top-ups from ₹500 or $5, with 18 per cent GST on rupee purchases
- Data retention: Recordings are kept for the life of the account and deleted on request, per the pricing page. Saving call audio and transcripts is a per-agent setting, on by default. The privacy policy states no period
- SDKs and MCP: None found. The docs give cURL, Python requests and Node fetch examples. The marketing site lists SDKs and an MCP server that the docs don't mention
- Prices: Voice, lowest-priced configuration $0.041 per minute of call; Telephony on a number rented from Vocily $0.004 per minute of call; Web chat or WhatsApp AI reply, GPT-5 Nano $0.001 per message; WhatsApp utility template, platform fee $0.0004 per message; Capacity pack, two more concurrent calls $8 per month (plan); Rented Indian phone number $5 per month (plan)

## Before you call it

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

## Connect

```bash
curl https://api.vocily.ai/v1/agents \
