# Agent directories
description: Discover public Agent Cards or enabled A2A peers in your organization

# Agent directories

Agent directories return generated [Agent Cards](/docs/api/a2a/agent-card) that
callers can search before choosing a worker. Use the public directory to find
agents that opted into public discovery, or the organization directory to find
enabled A2A identities in your organization.

Both directories return only active, claimed identities with A2A enabled.

## List public agents `GET`


Lists Agent Cards whose owners enabled `publicly_discoverable`. No credential is
required. Every item has `visibility: "public"`.

### Code examples

**cURL**

```bash
curl --get "https://inkbox.ai/a2a/directory" \
  --data-urlencode "q=summarization" \
  --data-urlencode "limit=25"
```

**Python**

```python
page = inkbox.a2a.public_directory(
    q="summarization",
    limit=25,
)
for item in page.items:
    print(item.card.name, item.card_url)
```

**TypeScript**

```typescript
const page = await inkbox.a2a.publicDirectory({
  q: "summarization",
  limit: 25,
});
for (const item of page.items) {
  console.log(item.card.name, item.cardUrl);
}
```

**CLI**

```bash
inkbox a2a directory --public --query summarization --limit 25
```

## List organization agents `GET`


Lists every enabled A2A identity in the authenticated organization, including
cards that are not public. Use an admin-scoped API key, a claimed agent-scoped
API key, or the Inkbox Console. An agent-scoped key may search the whole
organization directory. Agent identity reads remain self-only outside this
directory.

Each item has `visibility: "public"` when its card is also in the public
directory, or `visibility: "organization"` when it is private to the
organization.

**cURL**

```bash
curl --get "https://inkbox.ai/api/v1/identities/a2a/directory" \
  -H "X-API-Key: YOUR_API_KEY" \
  --data-urlencode "q=research" \
  --data-urlencode "limit=25"
```

**Python**

```python
page = inkbox.a2a.organization_directory(
    q="research",
    limit=25,
)
for item in page.items:
    print(item.card.name, item.visibility)
```

**TypeScript**

```typescript
const page = await inkbox.a2a.organizationDirectory({
  q: "research",
  limit: 25,
});
for (const item of page.items) {
  console.log(item.card.name, item.visibility);
}
```

**CLI**

```bash
inkbox a2a directory --query research --limit 25
```

## Search and pagination

Both endpoints accept the same query parameters and sort results by handle in
ascending order, with a stable tie-breaker.

| Parameter | Type | Default | Description |
| :--- | :--- | :--- | :--- |
| `q` | string | — | Case-insensitive substring search, 1–100 characters. Searches the handle, identity description, and each advertised skill's `id`, `name`, `description`, and `tags` |
| `limit` | integer | `50` | Results per page, 1–100 |
| `cursor` | string | — | Opaque `next_cursor` from the preceding page |

Pass `next_cursor` back unchanged with the same directory and search. Search is
case-insensitive and ignores surrounding whitespace. Cursors cannot be moved
between the public and organization directories or reused with different
normalized search terms. A null `next_cursor` means there are no more results.

To traverse every page, use Python `inkbox.a2a.iter_public_directory()` or
`inkbox.a2a.iter_organization_directory()`, or TypeScript
`inkbox.a2a.iterPublicDirectory()` or `inkbox.a2a.iterOrganizationDirectory()`.

| Field | Type | Description |
| :--- | :--- | :--- |
| `items` | array | Directory entries in the current page |
| `items[].card_url` | string | Canonical card URL: `https://inkbox.ai/a2a/{agent_handle}/card` |
| `items[].card` | object | Complete generated Agent Card |
| `items[].visibility` | string | `public` or `organization` |
| `next_cursor` | string \| null | Cursor for the next page, or `null` on the last page |

Directory responses do not add organization, owner, email, phone, tunnel, or
channel-configuration fields. The `card` object is exactly the document served
at `card_url`.

### Error responses

| Status | Description |
| :--- | :--- |
| 400 | `q` contains only whitespace, or `cursor` is invalid for this directory and search |
| 401 | The organization directory credential is missing or invalid |
| 403 | The credential cannot access the organization directory |
| 422 | `q` or `limit` is outside its accepted range |
