# Thread Usage

GET https://api.conductorquantum.com/v0/coda/usage/threads/{thread_id}

Post-hoc credit and token cost for every run on a conversation thread (`X-Thread-Id`). A thread rollup is not the complete ledger because `thread_id` attach is best-effort. Accepts `mcp:read` or `agents:run`.

Reference: https://docs.conductorquantum.com/api-reference/coda-api/usage/threads/get

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `thread_id` (string, required)

### Headers

- `x-api-path` (string, optional, nullable)

## Response

### 200

Successful Response

- `thread_id` (string, required)
- `requested_credits` (double, required)
- `charged_credits` (double, required)
- `tokens` (TokenUsage, required) — Metered model tokens. Prompt = input; completion = output.
- `runs` (list of UsageRun, required)

## Errors

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### TokenUsage

Metered model tokens. Prompt = input; completion = output.

- `prompt` (integer, required)

- `job_id` (string, required)
- `run_id` (string, required)
- `source` (string, required)
- `status` (string, required)
- `budget` (string, required)
- `requested_credits` (double, required) — Authorization hold reserved when the run started
- `charged_credits` (double, required) — Credits actually deducted after settlement or debt
- `tokens` (TokenUsage, required) — Metered model tokens. Prompt = input; completion = output.
- `created_at` (string, required)
- `thread_id` (string, optional, nullable)
- `team_id` (string, optional, nullable)
- `billed_team_id` (string, optional, nullable) — Team wallet that was debited, when spend used the shared team wallet
- `billable_credits` (double, optional, nullable) — Metered settlement amount, if priced
- `settled_at` (string, optional, nullable)

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
- `type` (string, required)
- `input` (any, optional)
- `ctx` (ValidationErrorCtx, optional)

### ValidationErrorLocItems
