# List daily call metrics

GET https://api.jelliu.co/api/analytics/calls-per-day

Returns one row per calendar day that had at least one call: volume, completions,
successes, explicit rejections, average sentiment and frustration, average duration,
average response latency, total cost and interruptions. It is the data behind a trend
chart of any of those metrics, for the whole workspace, one campaign or one agent.

**Filters.** `days` sets how far back to look (rolling window ending now, not aligned to
midnight, so the oldest day is usually partial; missing or out-of-range values become
30). `direction`, `campaignId` and `agentId` narrow every row. `timezone` decides which
calendar day a call falls in; an unknown zone name silently falls back to UTC.

**Ordering.** Ascending by `date`, at most 366 rows.

**No data.** Days without calls are omitted (no zero rows). Within a row, every average
is `null` when no call that day carried the measurement (for example `avgLatencyMs` on
calls recorded before telemetry existed), and `costUsd` / `interruptions` are `null`
when no call carried a cost or turn data. Counts are always integers.

**Idempotency.** Safe to retry: this is a read.

**Consistency.** Cached for 120 seconds, then served stale for up to 15 minutes while a
background refresh runs.

**Access**
- **Required scope:** `read`. Signed-in users need the owner, admin, member or viewer role.
- **Rate limit:** Analytics — 30 requests/min per workspace, in addition to the general API budget of your plan. See [Rate limits](/rate-limits).
- **Plan:** Available on every plan. A workspace without an active subscription (active, trialing or past due) gets `403 BILLING_ERROR`.

## 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

### Query parameters

- `days` (integer, optional, default: 30) — Size of the reporting window in days, ending now. On most analytics routes a missing or out-of-range value falls back to `30` instead of being rejected; the operation says when it is strict.
- `direction` (enum, optional, default: all) — Which calls to count: `inbound` (calls the agent answered), `outbound` (calls the agent placed) or `all` (both).
  - Allowed values: `inbound`, `outbound`, `all`
- `campaignId` (string, optional) — Scope every number to one campaign of the workspace. Omit it to aggregate across all campaigns and manual calls.
- `agentId` (string, optional) — Scope every number to one agent — the agent that served each call, so manual (campaign-less) calls count. Omit it to aggregate across agents.
- `timezone` (string, optional) — IANA time zone the day and hour buckets are computed in (default `UTC`). An unknown zone falls back to UTC; a value longer than 50 characters is rejected with `400`.

## Response

### 200

Daily rows in ascending date order.

- `data` (list of object, optional)
  - `date` (date, optional) — Calendar day, `YYYY-MM-DD`, in the requested timezone (UTC by default).
  - `total` (integer, optional) — Calls created that day, any status.
  - `completed` (integer, optional) — Calls with status `completed`.
  - `successes` (integer, optional) — Completed calls whose outcome is a success outcome of any category.
  - `rejected` (integer, optional) — Calls with an explicit refusal outcome (`rejected`, `appointment_canceled`, `payment_refused`, `churned`, `candidate_unqualified`).
  - `avgSentiment` (double, optional, nullable) — Mean sentiment (-1 to 1) of scored calls, two decimals. `null` when none were scored.
  - `avgFrustration` (double, optional, nullable) — Mean overall frustration (0 to 1), two decimals. `null` when no call carried it.
  - `avgDurationSeconds` (integer, optional, nullable) — Mean duration of completed calls, whole seconds. `null` when nothing completed.
  - `avgLatencyMs` (integer, optional, nullable) — Mean of each call's average agent response latency, milliseconds. `null` when no call carried latency telemetry.
  - `costUsd` (double, optional, nullable) — Total voice-provider cost of the day's calls in USD, four decimals. `null` when no call carried a cost.
  - `interruptions` (integer, optional, nullable) — Total times a person cut the agent off. `null` when no call carried turn data.

## Errors

### 400 Bad Request Error

`direction` is not `inbound`, `outbound` or `all`, `campaignId` or `agentId` is not a UUID, or `timezone` is longer than 50 characters.

- `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).
  - `message` (string, required) — Human-readable explanation. English or Spanish depending on the route; may change without notice.
  - `details` (object or list of object, optional) — Present on `VALIDATION_FAILED` only. Its shape depends on how the route validates: * a field map, either Zod's `flatten()` output (`{ "formErrors": [], "fieldErrors": { "name": ["..."] } }`) or just its `fieldErrors` part (`{ "name": ["..."] }`); * an issue list, where each issue has at least `path`, `message` and `code`. `path` is a dot-separated string on routes that let the schema throw, and an array of keys on routes that forward Zod's raw issues (those also carry Zod's extra issue fields).
    - Field map
      - `formErrors` (list of string, optional)
      - `fieldErrors` (map from string to list of string, optional)
  - `metadata` (map from string to any, optional) — Structured detail exposed for a small allowlist of codes only — for example `BILLING_ERROR` carries `limit`, `current` and `tier` (resource caps) or `tier` and `feature` (feature gates).

### 401 Unauthorized Error

No usable credential. Either the `Authorization` header is missing or is not a well-formed `Bearer jl_…` key, or the key is unknown, revoked or expired. Do not retry with the same key. See [Authentication](/authentication#401-unauthorized).

- `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).
  - `message` (string, required) — Human-readable explanation. English or Spanish depending on the route; may change without notice.
  - `details` (object or list of object, optional) — Present on `VALIDATION_FAILED` only. Its shape depends on how the route validates: * a field map, either Zod's `flatten()` output (`{ "formErrors": [], "fieldErrors": { "name": ["..."] } }`) or just its `fieldErrors` part (`{ "name": ["..."] }`); * an issue list, where each issue has at least `path`, `message` and `code`. `path` is a dot-separated string on routes that let the schema throw, and an array of keys on routes that forward Zod's raw issues (those also carry Zod's extra issue fields).

### 403 Forbidden Error

No active subscription, a signed-in role outside owner/admin/member/viewer, an API key without the `read` scope, or a suspended workspace.

- `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).
