How CallMissed Works

The Gateway

CallMissed is a single, OpenAI-compatible gateway in front of many AI providers. You point the official OpenAI (or Anthropic) SDK at https://api.callmissed.com/v1, authenticate with a cm_ key, and call chat, speech, image, and search — without integrating each provider yourself.

The same endpoint powers the dashboard playground and your production code, so behavior is identical everywhere.

1. 1

   Your app

   One SDK, one base URL, one key for every capability

2. 2

   CallMissed gateway

   Authenticate, enforce tenant isolation + rate limits, route by model id

3. 3

   Best provider

   the best-fit backend for each model — chosen automatically

4. 4

   Credits & logs

   Deduct from one credit balance and record usage for every request

Model Routing

The model id picks the backend. You never manage multiple SDKs or keys.

Every id is a plain CallMissed id. One API surface, one key, one bill.

Need a model that isn't in the catalog? We deploy 300+ more on demand — see Models on demand.

One Credit Currency

Every call — LLM tokens, STT minutes, TTS characters, an image, a web search — deducts credits. 1 credit = ₹1. This removes per-provider pricing math: top up once, spend across every capability. See Credits & Rate Limits for the per-service rates.

Tenancy & Isolation

Your organization is a tenant. Every user, bot, API key, conversation, and log belongs to exactly one tenant, and every database query is scoped to it — data is never shared across tenants. Roles (owner / admin / agent) gate sensitive actions, and you manage members and roles from the dashboard.

Channels vs APIs

There are two ways to use CallMissed:

• Direct APIs — call /v1/* from your own app (chat, speech, image, search, voice sessions).
• Channels — let CallMissed run a bot end-to-end on WhatsApp or voice calls, handling the inbound webhook, the AI turn, and the reply.
