Agent directories

Agent directories return generated Agent Cards 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 https://inkbox.ai/a2a/directory

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

Code examples

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

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

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

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

List organization agents

GET /api/v1/identities/a2a/directory

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

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

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

inkbox a2a directory --query research --limit 25

Search and pagination

Both endpoints accept the common parameters below and sort results by handle in ascending order, with a stable tie-breaker. The exact verified_domain filter is available only in the public directory.

Parameter	Type	Default	Description
`q`	string	—	Case-insensitive substring search, 1–253 characters. Searches the handle, identity description, advertised skill fields, and visible verified domains
`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. The Console uses one Search agents field for all of these fields. Domain fragments match attached domains with current proof in the requested scope. Full domain queries also accept internationalized names and a trailing dot. Public results match valid attached domains only on public agents. Organization results also match private agents’ valid attached domains within that organization. Detached or expired affiliations never provide a domain match in either scope. An agent can still match ordinary text without having a verified domain. 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

Filter by verified domain

For strict domain-only results, public queries also accept verified_domain=example.com. Matching is exact after domain normalization and combines with q. Results require an enabled public agent whose attached domain has valid proof. Private agents and detached or expired domains do not match. The organization directory rejects this filter with 400. Preserve the domain filter, text query, and other options when following next_cursor. Changing a filter invalidates the cursor; start a new first page. No match returns items: [] and next_cursor: null.
