# Retrieve a call

GET https://api.jelliu.co/api/calls/{callId}

Returns one call with every stored column (including `transcript`, transfer fields and telemetry), plus the derived `analysis`, `has_recording`, `agent_name`, `campaign_name` and `contact_name`. Use it after a `call.completed` / `call.failed` webhook, or to poll a call you placed with `POST /api/calls`.

**Consistency.** Cached for up to 5 minutes per call; the cache is invalidated when the call is closed (post-call webhook, reconciler, manual hang-up). Transcript and analysis arrive after the call ends and can lag it by seconds to minutes.

**Idempotency.** Read-only; safe to retry.

**Access**
- **Required scope:** `read` (or `write`).
- **Rate limit:** Outbound — 20 requests/min per workspace, shared by every `/api/calls` endpoint. See [Rate limits](/rate-limits).
- **Plan:** Available on every plan.

## Authentication

- `Authorization` header (bearer token, required) — Workspace API key: `jl_` followed by 64 lowercase hex characters, created by the workspace owner in the dashboard (**Settings → API Keys**) and sent as `Authorization: Bearer jl_...`. The plaintext is shown once, at creation; Jelliu stores only a SHA-256 hash. A workspace can hold up to 25 active keys. | Scope | GET / HEAD | POST / PUT / PATCH / DELETE | Admin-only routes | | --- | --- | --- | --- | | `read` | Yes | No | No | | `write` | Yes | Yes | No | | `full` | Yes | Yes | Yes | Operations restricted to admins or owners reject keys without the `full` scope with `403`, and say so in their description. No key, whatever its scope, can mint or revoke API keys or rotate a webhook secret — that requires a signed-in owner session. A revoked key stops authenticating within about 10 seconds. See [Authentication](/authentication).

## Request

### Path parameters

- `callId` (string, required) — The call's id. Must be a UUID (400 `Invalid call ID` otherwise).

## Response

### 200

The call.

- `data` (object, required) — A call as the API serializes it. Field names are snake\_case (raw database columns); timestamps are ISO-8601 strings. Vendor identifiers (carrier call SID, voice-provider conversation id) are never returned. Which fields are present depends on the endpoint: * `GET /api/calls/{callId}` returns every field below. * `GET /api/calls` (list) returns a slimmer row: it omits `transcript`, `first_response_ms`, `transfer_call_sid`, `transferred_at`, `transferred_to`, `kpi_data`, `llm_cost_usd`, `llm_input_tokens`, `llm_output_tokens`, `sentiment_timeline`, `telemetry_fetched_at`, `tool_call_count`, `mcp_call_count`, `rag_lookup_count`, `tool_result_bytes` and `dnc_scanned_at`. * `POST /api/calls` returns the stored row without the derived fields (`analysis`, `has_recording`, `agent_name`, `campaign_name`, `contact_name`). Telemetry fields are `null` when not measured, which is not the same as 0. Every field is server-generated; calls cannot be edited through the API.

## Errors

### 400 Bad Request Error

`callId` is not a UUID.

- `error` (object, required) — The error object. Always has `code` and `message`.
  - `code` (string, required) — Stable machine-readable error code (for example `VALIDATION_FAILED`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `BILLING_ERROR`, `COMPLIANCE_BLOCKED`, `RATE_LIMIT_EXCEEDED`, `INTERNAL_ERROR`). Switch on this, not on `message`. See [Errors](/errors).
