# Managed Agents — Endpoint Reference
|
||
|
||
All endpoints require `x-api-key` and `anthropic-version: 2023-06-01` headers. Managed Agents endpoints additionally require the `anthropic-beta` header.
|
||
|
||
## Beta Headers
|
||
|
||
```
|
||
anthropic-beta: managed-agents-2026-04-01
|
||
```
|
||
|
||
The SDK adds this header automatically for all `client.beta.{agents,environments,sessions,vaults,memory_stores}.*` calls. Skills endpoints use `skills-2025-10-02`; Files endpoints use `files-api-2025-04-14`.
|
||
|
||
---
|
||
|
||
## SDK Method Reference
|
||
|
||
All resources are under the `beta` namespace. Python and TypeScript share identical method names.
|
||
|
||
| Resource | Python / TypeScript (`client.beta.*`) | Go (`client.Beta.*`) |
|
||

||
| Agents | `agents.create` / `retrieve` / `update` / `list` / `archive` | `Agents.New` / `Get` / `Update` / `List` / `Archive` |
|
||
| Agent Versions | `agents.versions.list` | `Agents.Versions.List` |
|
||
| Environments | `environments.create` / `retrieve` / `update` / `list` / `delete` / `archive` | `Environments.New` / `Get` / `Update` / `List` / `Delete` / `Archive` |
|

|
||
| Vaults | `vaults.create` / `retrieve` / `update` / `list` / `delete` / `archive` | `Vaults.New` / `Get` / `Update` / `List` / `Delete` / `Archive` |
|
||
| Credentials | `vaults.credentials.create` / `retrieve` / `update` / `list` / `delete` / `archive` / `mcp_oauth_validate` | `Vaults.Credentials.New` / `Get` / `Update` / `List` / `Delete` / `Archive` / `McpOauthValidate` |
|
||
| Memory Stores | `memory_stores.create` / `retrieve` / `update` / `list` / `delete` / `archive` | `MemoryStores.New` / `Get` / `Update` / `List` / `Delete` / `Archive` |
|
||
| Memories | `memory_stores.memories.create` / `retrieve` / `update` / `list` / `delete` | `MemoryStores.Memories.New` / `Get` / `Update` / `List` / `Delete` |
|
||
| Memory Versions | `memory_stores.memory_versions.list` / `retrieve` / `redact` | `MemoryStores.MemoryVersions.List` / `Get` / `Redact` |
|
||
|
||
**Naming quirks to watch for:**
|
||
- Agents and Session Threads have **no delete** — only `archive`. Archive is **permanent**: the agent becomes read-only, new sessions cannot reference it, and there is no unarchive. Confirm with the user before archiving a production agent. Environments, Sessions, Vaults, Credentials, and Memory Stores have both `delete` and `archive`; Session Resources, Files, Skills, and Memories are `delete`-only; Memory Versions have neither — only `redact`.
|
||
- Session resources use `add` (not `create`).
|
||
- Go's event stream is `StreamEvents` (not `Stream`).
|
||
|
||
**Agent shorthand:** `agent` on session create accepts either a bare string (`agent="agent_abc123"` — uses latest version) or the full reference object (`{type: "agent", id: "agent_abc123", version: 123}`).
|
||
|
||
**Model shorthand:** `model` on agent create accepts either a bare string (`model="{{OPUS_ID}}"` — uses `standard` speed) or the full config object (`{type: "model_config", id: "claude-opus-4-6", speed: "fast"}`). Note: `speed: "fast"` is only supported on Opus 4.6.
|
||
|
||

|
||
|
||
## Agents
|
||
|
||
**Step one of every flow.** Sessions require a pre-created agent — there is no inline agent config under `managed-agents-2026-04-01`.

## Vaults
|
||
|
||
Vaults store MCP credentials that Anthropic manages on your behalf — OAuth credentials with auto-refresh, or static bearer tokens. Attach to sessions via `vault_ids`. See `managed-agents-tools.md` §Vaults for the conceptual guide and credential shapes.

| `POST` | `/v1/vaults/{vault_id}/credentials/{credential_id}/mcp_oauth_validate` | McpOauthValidate | Validate an MCP OAuth credential |
|
||
|
||
## Memory Stores
|
||
|
||
Workspace-scoped persistent memory that survives across sessions. Attach to a session via a `{"type": "memory_store", "memory_store_id": ...}` entry in `resources[]` (session-create time only). See `shared/managed-agents-memory.md` for the conceptual guide, the FUSE-mount agent interface, preconditions, and versioning.
|
||
|
||
| Method | Path | Operation | Description |
|
||
| -------- | ------------------------------------------------ | ------------------ | ---------------------------------------- |
|
||
| `POST` | `/v1/memory_stores` | CreateMemoryStore | Create a store (`name`, `description`, `metadata`) |
|
||
| `GET` | `/v1/memory_stores` | ListMemoryStores | List stores (`include_archived`, `created_at_{gte,lte}`) |
|
||
| `GET` | `/v1/memory_stores/{memory_store_id}` | GetMemoryStore | Get store details |
|
||
| `POST` | `/v1/memory_stores/{memory_store_id}` | UpdateMemoryStore | Update store |
|
||
| `DELETE` | `/v1/memory_stores/{memory_store_id}` | DeleteMemoryStore | Delete store |
|
||
| `POST` | `/v1/memory_stores/{memory_store_id}/archive` | ArchiveMemoryStore | Archive store. Makes it **read-only**; existing sessions continue, new sessions cannot reference it. No unarchive. |
|
||
|
||
## Memories
|
||
|
||
Individual text documents inside a store (≤ 100KB each). `create` creates at a `path` and returns `409` (`memory_path_conflict_error`, with `conflicting_memory_id`) if the path is occupied; `update` mutates by `mem_...` ID (rename and/or content). Only `update` accepts a `precondition` (`{"type": "content_sha256", "content_sha256": ...}`) — on mismatch returns `409` (`memory_precondition_failed_error`). List endpoints accept `view: "basic"|"full"` (controls whether `content` is populated; `retrieve` defaults to `full`).
|
||
|
||
| Method | Path | Operation | Description |
|
||
| -------- | ----------------------------------------------------------------- | -------------- | ---------------------------------------- |
|
||
| `GET` | `/v1/memory_stores/{memory_store_id}/memories` | ListMemories | Returns `Memory \| MemoryPrefix`; filter by `path_prefix`, `depth`, `order_by`/`order` |
|
||
| `POST` | `/v1/memory_stores/{memory_store_id}/memories` | CreateMemory | Create at `path` (SDK: `memories.create`); `409 memory_path_conflict_error` if occupied |
|
||
| `GET` | `/v1/memory_stores/{memory_store_id}/memories/{memory_id}` | GetMemory | Read one memory (defaults to `view="full"`) |
|
||
| `PATCH` | `/v1/memory_stores/{memory_store_id}/memories/{memory_id}` | UpdateMemory | Change `content`, `path`, or both by ID; optional `precondition` |
|
||
| `DELETE` | `/v1/memory_stores/{memory_store_id}/memories/{memory_id}` | DeleteMemory | Delete (optional `expected_content_sha256`) |
|
||
|
||
## Memory Versions
|
||
|
||
Immutable per-mutation snapshots (`memver_...`) — the audit and rollback surface. `operation` ∈ `created` / `modified` / `deleted`.
|
||
|
||
| Method | Path | Operation | Description |
|
||

## Request/Response Schema Quick Reference
|
||
|
||
### CreateAgent Request Body
|
||
|
||
**Always start here.** `model`, `system`, `tools`, `mcp_servers`, `skills` are top-level fields on this object — they do NOT go on the session.
|
||
|
||
```json
|
||
{
|
||
"name": "string (required, 1-256 chars)",
|
||
"model": "{{OPUS_ID}} (required — bare string, or {id, speed} object)",
|
||
"description": "string (optional, up to 2048 chars)",
|
||
"system": "string (optional, up to 100,000 chars)",
|
||
"tools": [
|
||
{ "type": "agent_toolset_20260401" }

|
||
{ "type": "custom", "skill_id": "skill_abc123", "version": "1" }
|
||
],
|
||
"mcp_servers": [
|
||
{
|
||
"type": "url",
|
||
"name": "github",
|
||
"url": "https://api.githubcopilot.com/mcp/"
|
||
}
|
||
],
|
||
"multiagent": {
|
||
"type": "coordinator",
|
||
"agents": [
|
||
"agent_abc123",
|
||
{ "type": "agent", "id": "agent_def456", "version": 4 },

|
||
]
|
||
},
|
||
"metadata": {
|
||
"key": "value (max 16 pairs, keys ≤64 chars, values ≤512 chars)"
|

}
|
||
```
|
||
|
||
> Limits: `tools` max 128, `skills` max 20, `mcp_servers` max 20 (unique names). `multiagent.agents` 1–20 entries (string ID | `{type:"agent",id,version?}` | `{type:"self"}`) — see `shared/managed-agents-multiagent.md`.
|
||
|
||
### CreateSession Request Body
|
||
|
||
```json
|
||
{
|
||
"agent": "agent_abc123 (required — string shorthand for latest version, or {type: \"agent\", id, version} object)",
|
||
"environment_id": "env_abc123 (required)",

|
||
"metadata": {
|

"key": "value"
|
||
}
|
||
}
|
||
```
|
||
|
||
> The `agent` field accepts only a string ID or `{type: "agent", id, version}` — `model`/`system`/`tools` live on the agent, not here.
|
||
>
|
||
> **`checkout`** accepts `{type: "branch", name: "..."}` or `{type: "commit", sha: "..."}`. Omit for the repo's default branch.

}
|
||
```
|
||
|
||

|
||
|
||
## Error Handling
|
||
|
||
Managed Agents endpoints use the standard Anthropic API error format. Errors are returned with an HTTP status code and a JSON body containing `type`, `error`, and `request_id`:
|
||
|
||
```json
|
||
{
|
||
"type": "error",
|
||
"error": {
|
||
"type": "invalid_request_error",
|
||
"message": "Description of what went wrong"
|
||
},
|
||
"request_id": "req_011CRv1W3XQ8XpFikNYG7RnE"
|
||
}
|
||
```
|
||
|
||
Include the `request_id` when reporting issues to Anthropic — it lets us trace the request end-to-end. The inner `error.type` is one of the following:
|
||
|
||
| Status | Error type | Description |
|
||
|---|---|---|
|
||
| 400 | `invalid_request_error` | The request was malformed or missing required parameters |
|
||
| 401 | `authentication_error` | Invalid or missing API key |
|
||
| 403 | `permission_error` | The API key doesn't have permission for this operation |
|
||
| 404 | `not_found_error` | The requested resource doesn't exist |
|
||
| 409 | `invalid_request_error` | The request conflicts with the resource's current state (e.g., sending to an archived session) |
|
||
| 413 | `request_too_large` | The request body exceeds the maximum allowed size |
|
||
| 429 | `rate_limit_error` | Too many requests — check rate limit headers for retry timing |
|
||
| 500 | `api_error` | An internal server error occurred |
|
||
| 529 | `overloaded_error` | The service is temporarily overloaded — retry with backoff |
|
||
|
||
Note that `409 Conflict` carries `error.type: "invalid_request_error"` (there is no separate `conflict_error` type); inspect both the HTTP status and the `message` to distinguish conflicts from other invalid requests.

## Rate Limits
|
||
|
||
Managed Agents endpoints have per-organization request-per-minute (RPM) limits, separate from your [Messages API token limits](https://platform.claude.com/docs/en/api/rate-limits). Model inference inside a session still draws from your organization's standard ITPM/OTPM limits.
|
||
|
||
| Endpoint group | Scope | RPM | Max concurrent |
|
||
|---|---|---|---|
|
||
| Create operations (Agents, Sessions, Vaults) | organization | 300 | — |
|
||
| All other operations (Agents, Sessions, Vaults) | organization | 600 | — |
|
||
| All operations (Environments) | organization | 60 | 5 |
|
||
|
||
Files and Skills endpoints use the standard tier-based [rate limits](https://platform.claude.com/docs/en/api/rate-limits).
|
||
|
||
When a limit is exceeded the API returns `429` with a `rate_limit_error` (see [Error Handling](#error-handling) for the response envelope) and a `retry-after` header indicating how many seconds to wait before retrying. The Anthropic SDK reads this header and retries automatically.
