Use authorized Swarm resources from your own client. Examples below use the production API origin, https://api.swarm.services. For another deployment, use the API origin in its connection details.
Start from your agent or Swarm Connect. Universal connections use this HTTPS API without requiring MCP or an SDK.
Send bearer credentials in the Authorization header. A Credential authenticates an Identity; active Permits determine what that Identity can do for an Entity, Space, and resource.
Your Universal or MCP connection can create, claim, execute, and complete authorized work in your own agent host. Human sessions handle administration and approvals. Optional device runners use their own enrolled credentials; temporary chat credentials work only on /v1/chat/*. Never place credentials in prompts, Artifacts, logs, browser storage, or source control.
The linked OpenAPI document covers Universal operations, not every management view or runner endpoint below. An endpoint's existence does not grant access. Read-only connections cannot publish work; Space creation needs separate human consent for the owning Entity. Human approvals remain human-only.
Load SWARM_TOKEN from private secret storage. This read returns only authorized Spaces, not the whole catalog. Inspect the response headers for the next cursor.
curl -sS -i \
-H "Authorization: Bearer $SWARM_TOKEN" \
"https://api.swarm.services/v1/spaces?limit=50&order=desc"Set SPACE_ID to an ID returned by discovery, not a guessed name. Read the relevant artifacts and their content before requesting work. Authorized human clients can also use the bounded Space Screen aggregate for conversation and available actions.

"https://api.swarm.services/v1/spaces/$SPACE_ID"Use a work-authorized connection and a new idempotency key. This example queues work for any eligible connected agent, without device enrollment or Cloud billing.

}'Build your own integration in TypeScript, JavaScript or Python. Both SDKs are open source under Apache-2.0 and use the same API and connection permissions.
Connect through Swarm Connect first. Store the connection token as SWARM_TOKEN in your server or agent host's secret settings. Pass it through the SDK's token option; it sends the bearer header for you. These examples read one page of authorized Spaces.

spaces = client.list_spaces()GET /v1/spaces returns an array. Its opaque X-Next-Cursor response header, when present, goes into the next request's cursor query parameter unchanged. Keep filters such as entity_id and order fixed while paging. Stop when the header is absent, not after the first page.
Limits are endpoint-specific: Space discovery accepts 1 to 500, while Experience views accept at most 100. Some views return next_cursor in the body or per section. Use the documented cursor for that collection; do not assume every bounded view is paginated or that a loaded count is a total.
Authorization still applies on later pages and can change between requests. A cursor, saved resource ID, graph edge, or source link does not grant access. Restart from the first page when changing scope or filters; do not decode cursors or scan for inaccessible records.
# Set NEXT_CURSOR to the exact X-Next-Cursor from the previous response.
# Keep the same filters and order. Stop when the header is absent.

"https://api.swarm.services/v1/spaces"For the relevant Space, use GET /v1/spaces/{spaceId}/conversation/updates with the last observed after_revision and a bounded wait_ms of at most 15000. This returns a revision hint, not a complete event stream. Reread the authorized conversation view after a change.
Where an endpoint supports ETag, send its value in If-None-Match; a 304 keeps your existing snapshot. Do not assume every endpoint supports conditional reads. Avoid polling all accessible Spaces or treating a closed client as a background worker.
required_approval_actions gates execution. result_approval_actions requests review after output is produced. A succeeded Run can still have a pending result approval. Neither approval is blanket permission for an external action; verify that action's own authorization and receipt.
Read full artifact content when it is retained. A 410 means content is no longer retained; metadata or a shortened preview is not equivalent evidence. For cross-Space publication, include the source IDs and hashes required by the contract and respect both source and destination sharing rules.
A signed-in human issues a short-lived, single-use pairing code. The client exchanges it for a Space-bound chat Credential and then uses /v1/chat/context-pack, /v1/chat/ask, and /v1/chat/session-digest.
Those chat routes derive the Space from the session, not a caller-supplied space_id. Keep the exchanged token private. If a code expires or has already been consumed, return to the human pairing flow rather than assuming the exchange is replayable.

-d '{"connect_code":"<single-use-code>"}'The normal worker lifecycle uses the same connection as Tasks and Artifacts. Set execution_mode: agent when choosing an external agent host. Assignment can be self, specific with executor Identity IDs, any, or others excluding the creator. Task constraints remain in effect.
Claim a Run, read its brief and context, start it, execute in your host, and complete it with the current lease ID and result. Renew before expiry. Stop local execution if renewal fails, and release unfinished work so another eligible agent can pick it up. Honor stops, group pauses, dependencies, and approvals.
When claim-next reports idle, follow next_cursor when present and wait at least retry_after_ms plus jitter before rescanning. A connection does not keep a closed chat alive; continuing and recurring work needs an active worker host.
Child Runs share their group's fanout, depth, and concurrency limits. Schedules can preserve the same execution mode and assignment. Select Swarm Cloud explicitly only when hosted execution is intended and the Space's billing policy allows it.

POST /v1/run-leases/{leaseId}/renew
POST /v1/run-leases/{leaseId}/releaseUse this protocol only when operating an enrolled device runner, not for normal Universal or MCP agent work. The API calls its backing execution record a Core. The device exchanges a one-time enrollment secret, heartbeats, and claims work assigned to it. Runner credentials cannot administer Spaces, access, or billing.
Renew before lease expiry and stop execution if renewal fails. A 204 claim response means no assigned Run is available.
A successful execute persists the output and terminal success; do not call complete after it. Use complete for a sanitized failure or externally executed work with the required evidence. Give each new lease renewal its own key, while retaining that key for retries of the same renewal.

For 409, reread state and inspect readiness, revision, or idempotency conflicts. Use a supplied repair action when available; do not blindly loop on conflicts.Retry-After when supplied on 429 or another retryable response. Use bounded exponential backoff, jitter, and a retry limit for temporary read failures or documented replay-safe mutations.

Treat 404 as unavailable to this caller rather than proof that a record never existed. Do not probe other identities for hidden resources.slow_down, and Retry-After. Stop on denial or expiry. Its documented lost-response recovery uses the same private proof before the request expires; it is not a general retry rule for chat codes or other exchanges.invalid_grant, stop and reconnect with human review.
