This raises the ceiling by one block. Refused while the current block is still dialing, so the outcomes it exists to show are in before the next one starts. ## OpenAPI ````yaml /openapi/api-public-v1.yaml post /batches/{id}/blocks/next openapi: 3.0.3 info: title: Vodex API (v1) description: > The **public Vodex `/v1` REST API** — everything a customer's own systems integrate with: assistants, telephony (numbers, trunks, carrier integrations), calls and recordings, batch dialing, the SMS channel, and outbound webhooks. This is deliberately a **subset**. Account and console-only routes (`/v1/auth/*`, `/v1/api-keys`, `/v1/usage`), platform provisioning (`/v1/platform/*`), Vodex support operations, and endpoints other systems call inward (carrier delivery receipts, the agent worker, cron) are not part of the published surface and are not documented here. The **data plane** (LiveKit SFU + SIP + the agent worker) is not an HTTP API and is not described here: a call reaches the worker over LiveKit, with its config carried in participant metadata or read from the config snapshot this API publishes. ## Authentication | Credential | Sent as | Scope | |---|---|---| | **Tenant API key** | `Authorization: Bearer vdx_live_…` | One customer, full access — the credential for everything in this document | Mint an API key in the console (**Settings → API keys**). The plaintext is shown **once**, by the call that creates it, and no endpoint reads one back — a lost key is replaced, not recovered. Every route here also answers a signed-in console session, because the console is built on this same API. That is **not** an integration credential and is deliberately not described as one: it is the console's own cookie, it carries a role an API key never has, and it is free to change. Integrate with `vdx_live_`. ## Customers and tenants One thing, two words, and they are not interchangeable: - **Customer** is the product word — what a human calls the account, and what the console shows you. - **Tenant** is the same thing's identity on the wire and in storage: `tenantId` on every response. **A *workspace* is a third thing, and not a synonym for either.** Tenancy is mapped at the customer level deliberately: integrations (carrier, SMS, provider credentials) live above the workspaces that use them, so mapping workspaces to tenants would fragment one customer's telephony across tenants that then have to share credentials. A workspace is therefore a **label inside the tenant** (`externalWorkspaceRef`) — for filtering and attribution, never isolation. Anything that must not be shared between one customer's workspaces needs its own tenant. ## Tenancy There is **no tenant parameter**. Every tenant-scoped route derives its tenant from the credential and binds it for the whole request, so a caller cannot ask for another tenant's data by changing a query string. An id that belongs to somebody else answers `404`, never `403` — "no such call" is the only thing worth confirming. ## Response shapes Resources are returned **flat**, at the top level (`{ "id": "…", … }`) — there is no envelope object. Collections vary by age of the endpoint: - Newer lists are `{ "": [ … ], "total": n, "limit": n, "offset": n }` (`calls`, `batches`, `rows`, `attempts`, `messages`). - Older lists return a **bare JSON array** (`/v1/phone-numbers`, `/v1/sip-trunks`, `/v1/integrations`, `/v1/carriers`, `/v1/console/assistants`, `/v1/sms/configurations`). Deletes and side-effecting no-content operations return `{ "ok": true }`. ## Errors ```json { "error": "human-readable message" } ``` A flat string, not a coded object — HTTP status is the machine signal. The one exception is quota exhaustion (`402`), which adds a stable `code: "quota_exhausted"` plus the counters the console renders. ## Pagination `?limit=` and `?offset=`, with `total` in the body. Defaults and ceilings differ per endpoint (calls 25/100, batch rows 50/500, attempts 100/500) and are stated on each operation. ## Conventions - **Phone numbers** are E.164 strings (`+14155551234`); `+91…` numbers are served from Mumbai, `+1…` from us-central1. - **Money** is a JSON number of **USD** (`costUsd`), not a decimal string. - **Timestamps** are ISO‑8601 UTC strings, except the calls list, which reports `mtime` / `startedAt` as epoch **milliseconds** and durations as **milliseconds**. - **Ids** are unprefixed: batches, rows, attempts and SMS rows are UUIDs; a call id is its LiveKit room name (`call-…`, or `console-…` for web calls); a phone number's id is `num-`; a trunk's is `trunk-…`. - **Secrets** (`vdx_live_…`, `whsec_…`) are returned exactly once, by the call that mints them. No endpoint reads one back — carrier and provider credentials are stored in Secret Manager and echoed only as a non-reversible fingerprint. - **Idempotency**: `POST /v1/sms` and `POST /v1/batches` **require** an `Idempotency-Key` header. Only successful (2xx) responses are replayed; a failed attempt releases the key so a corrected retry can reuse it. version: 1.0.0 contact: name: Vodex Platform url: https://vodex.ai license: name: Proprietary url: https://vodex.ai/terms servers: - url: https://apiv2.vodex.ai/v1 description: Production security: - ApiKeyBearer: [] tags: - name: Assistants description: Assistant configurations (the agent's engine, prompt, slots, tools). - name: Console description: Reference data (model catalog, voices) and the web-call token. - name: Usage description: Minute usage against the plan. - name: Calls description: Place calls, read the call log, fetch traces and recordings. - name: Phone Numbers description: Number inventory and assistant mapping. - name: SIP Trunks description: Customer-owned (BYO) SIP trunks. - name: Carriers description: Carrier registry — what can be connected, and how. - name: Integrations description: Connected carrier accounts and their numbers. - name: Batches description: Batch dialing — lists in, calls out. - name: Number Rotation description: Per-number spacing, daily caps, and cooldown. - name: Callbacks description: >- "Call me Tuesday afternoon" — appointments booked mid-call, and dialed later. - name: SMS description: SMS configurations, credentials, preview, send, and message log. - name: Webhooks description: Outbound webhook configuration and delivery records. - name: Tenants description: Recording retention. - name: Contacts description: >- The people a tenant calls — records, channels, custom attributes, files, and CSV import. - name: Audiences description: >- Saved filters over contacts.
