**V5** is the current generation of the Supermemory HTTP API. It keeps the resource model you already know — documents, memories, profiles, container tags — and organizes the operations by **workflow** instead of by internal service.

This section is the contract-level reference. Every operation listed here is grouped by the job it does, with the request and response shapes the API actually accepts.

## Base URL

```
https://api.supermemory.ai
```

Self-hosted deployments use your own instance URL (for example `http://localhost:6767`). See [Self-hosting](/self-hosting/overview).

Operations in this reference are versioned by path segment. The paths on these pages carry their own version prefix — for example `POST /v4/search` — so you always know which contract you are calling.

## Authentication

Every request is authenticated with a Bearer API key:

```bash
Authorization: Bearer $SUPERMEMORY_API_KEY
```

Create and rotate keys in the [developer console](https://console.supermemory.ai). Full details, including self-hosted keys: [API keys & auth](/authentication).

<CodeGroup>

```bash cURL
curl -X POST "https://api.supermemory.ai/v4/search" \
  --header "Authorization: Bearer $SUPERMEMORY_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{"q": "machine learning", "containerTag": "user_123"}'
```

```typescript Typescript
import Supermemory from 'supermemory';

const client = new Supermemory({
  apiKey: process.env.SUPERMEMORY_API_KEY,
});

const results = await client.search({
  q: "machine learning",
  containerTag: "user_123",
});
```

```python Python
from supermemory import Supermemory

client = Supermemory()

results = client.search.memories(
    q="machine learning",
    container_tag="user_123",
)
```

</CodeGroup>

## Legacy and Latest

The API is versioned by path prefix. Two reference sections are published side by side, and each documents a mix of prefixes:

- **[Legacy API Reference](/api-reference/overview)** — the reference generated from the OpenAPI document below, covering the long-served operations. Calls keep working; new capabilities are not added there.
- **V5 API Reference** (this section) — the workflow-organized reference. Each operation carries its own path prefix, so `POST /v3/search` and `POST /v4/search` both appear here.

<Note>
The version prefix is part of the path, not a header. Pin the prefix you were written against — `POST /v3/documents` and `POST /v4/search` are separate contracts, and a change to one does not silently change the other.
</Note>

| Prefix | Used by |
| --- | --- |
| `/v3` | Documents, ingest, document/SuperRAG search, connections, settings, container tags, usage analytics |
| `/v4` | Memory search, profiles, memories, conversations |

When you start a new integration, follow the workflow pages in this section; each names the exact prefix it calls. Existing integrations can keep calling the prefixes they were written against until they are ready to migrate.

## Operations by workflow

The groups below mirror how you use the API, in the order you typically call it.

| Workflow | What it covers |
| --- | --- |
| [Ingest](/v5/api-reference/ingest) | Add documents, files, batches, and conversations into the pipeline |
| [Search](/v5/api-reference/search) | Semantic recall over memories, document chunks, or both |
| [Content management](/v5/api-reference/content-management) | List, inspect, update, and delete ingested documents |
| [Namespaces](/v5/api-reference/namespaces) | `containerTag` lifecycle — settings, projects, and deletion |
| [Organization](/v5/api-reference/organization) | Org-level settings, analytics, and reset |
| [Profiles](/v5/api-reference/profiles) | Static and dynamic facts for a container |
| [Connections](/api-reference/connections) | Create, sync, and manage external connectors — see the Legacy reference |

<Note>
Connection operations are managed through the [Connections reference](/api-reference/connections) in the Legacy API Reference: `POST /v3/connections/{provider}`, `POST /v3/connections/list`, `GET /v3/connections`, `GET /v3/connections/{connectionId}`, `DELETE /v3/connections/{connectionId}`, `GET /v3/connections/{connectionId}/sync-runs`, and `POST /v3/connections/{provider}/import`.
</Note>

## Suggested reading order

1. **[Ingest](/v5/api-reference/ingest)** — `POST /v3/documents` returns an id immediately.
2. **[Content management](/v5/api-reference/content-management)** — poll `GET /v3/documents/{id}` until `status: "done"`.
3. **[Search](/v5/api-reference/search)** — recall what was indexed.
4. **[Profiles](/v5/api-reference/profiles)** — read the compacted view of a container.

Everything is scoped by `containerTag`, the same key across ingest, search, and profiles. See [Container tags](/concepts/container-tags) for the multi-tenancy model.

## SDKs

The official clients wrap these operations:

- TypeScript: `npm install supermemory`
- Python: `pip install supermemory`

See [Supermemory SDK](/integrations/supermemory-sdk). Narrative guides — when to use which operation, and end-to-end patterns — live under [Using supermemory](/using-supermemory) and the [Quickstart](/quickstart).

## Errors

Failures return a JSON body with an `error` message and an optional `details` string:

```json
{
  "error": "Invalid request parameters",
  "details": "Query must be at least 1 character long"
}
```

## OpenAPI

The operations on these pages are backed by the generated OpenAPI document that also drives the [Legacy API Reference](/api-reference/overview):

- Spec (live): [https://api.supermemory.ai/v4/openapi](https://api.supermemory.ai/v4/openapi)

That document describes the version-prefixed operations the API serves. This reference reorganizes the same operations by workflow, so you can read them in the order you call them.
