# List tool calls

GET https://api.runtype.com/v1/agents/{id}/executions/{executionId}/tool-calls

List tool calls for a single agent execution. Returns a compact payload without input/output JSON — use the detail endpoint for full payloads. `executionId` is the execution row id (`aex_…`) or the run id the stream reports (`exec_…`). A call paused at an approval gate is `awaiting_approval` until decided, then carries the outcome; a declined call is `denied`, not `failed`.

Reference: https://docs.runtype.com/api-reference/runtype-api/agents/list-tool-calls

## Authentication

- `Authorization` header (bearer token, required) — API key or Clerk session token

## Servers

- `https://api.runtype.com` (Production, default)
- `https://api.runtype-staging.com` (Staging)

## Request

### Path parameters

- `id` (string, required)
- `executionId` (string, required) — The execution row id (`aex_…`) or the run id the stream reports (`exec_…`).

## Response

### 200

Tool calls for the execution

### 401 Unauthorized Error

Unauthorized

- `error` (string, required)
- `code` (string, optional) — Stable error code. `insufficient_scope` marks an API key that lacks a scope this request needs.
- `details` (list of ErrorDetailsItems, optional)
- `requiredScopes` (list of string, optional) — On `insufficient_scope`: every API key scope this request needs.

### 403 Forbidden Error

Insufficient permissions

- `error` (string, required)
- `code` (string, optional) — Stable error code. `insufficient_scope` marks an API key that lacks a scope this request needs.

### 404 Not Found Error

Agent or execution not found

- `error` (string, required)
- `code` (string, optional) — Stable error code. `insufficient_scope` marks an API key that lacks a scope this request needs.

### 500 Internal Server Error

Internal server error

- `error` (string, required)
- `code` (string, optional) — Stable error code. `insufficient_scope` marks an API key that lacks a scope this request needs.

- `requiredScopes` (list of string, optional) — On `insufficient_scope`: every API key scope this request needs.

## Types

### V1AgentsIdExecutionsExecutionIdToolCallsGetResponsesContentApplicationJsonSchemaToolCallsItems

- `completedAt` (string, required, nullable) — ISO timestamp derived as startedAt plus executionTimeMs. Null while the call has no recorded duration.
- `createdAt` (string, required)
- `errorMessage` (string, required, nullable)
- `executionTimeMs` (integer, required, nullable)
- `id` (string, required)
- `inputTruncated` (boolean, required)
- `iteration` (integer, required, nullable)
- `model` (string, required, nullable)
- `outputTruncated` (boolean, required)
- `startedAt` (string, required) — ISO timestamp the tool call started. Same instant as createdAt: the row is inserted when the tool starts, then updated in place with its result.
- `status` (string, required) — 'pending' | 'success' | 'failed' | 'waiting_for_local' | 'awaiting_approval' (paused at an approval gate, undecided) | 'denied' (the approver declined; the tool never ran).
- `toolCallId` (string, required, nullable) — The model's own tool-call id (tool_executions.external_tool_call_id), matching the toolCallId a log row carries. Null for a run whose tool rows were written by this API rather than ingested from an external trace.
- `toolDescription` (string, required, nullable)
- `toolName` (string, required)
- `inputParameters` (any, optional) — Recorded tool input. Replaced by \{ truncated: true, preview } when its JSON text exceeds 16 KiB; the per-call detail endpoint always returns the full value.
- `outputResult` (any, optional) — Recorded tool output. Replaced by \{ truncated: true, preview } when its JSON text exceeds 16 KiB; the per-call detail endpoint always returns the full value.

### ErrorDetailsItems

- `message` (string, required)
- `code` (string, optional) — Stable Runtype validation code (e.g. MISSING_REQUIRED_FIELD, INVALID_ENUM).
- `path` (string, optional) — Dotted JSON path to the offending field.
- `suggestion` (string, optional) — Actionable hint (allowed values, accepted range, …).
