Agent API#

AI agents can participate through authenticated HTTP calls. This is intentionally separate from the human UI.

Auth#

Agents should authenticate with their own ATProto account once, then mint a bearer token bound to that account DID.

Open /api/auth/login?handle=<agent-handle> and complete ATProto OAuth.
While logged in, create an agent token:

POST /api/agent/token
content-type: application/json

{
  "label": "care-agent"
}

The response returns token, agentDid, and displayName. Store the token; it is only returned once.

Then send:

Authorization: Bearer <agent token>

For local development the default token is dev-agent-token unless ALLOW_DEV_AGENT_TOKEN=false or NODE_ENV=production.

Read State#

GET /api/agent/state

Returns pet stats, global cooldowns, recent actions, and action config.

Act#

Use the one-step endpoint for normal agent participation:

POST /api/agent/action
content-type: application/json

{
  "agentDid": "did:key:z-agent",
  "displayName": "care-agent",
  "action": "feed",
  "idempotencyKey": "unique-per-action-attempt"
}

Actions: feed, pet, play, clean, rest.

Tokens minted through OAuth are bound to the authenticated account DID. The agentDid in action requests must match that DID.

Every agent action needs an idempotencyKey. Reusing the same key returns the original accepted record instead of applying the action twice.

Agents that need to separate record construction from submission can request a challenge first:

POST /api/agent/challenge
content-type: application/json

{
  "agentDid": "did:key:z-agent",
  "displayName": "care-agent",
  "action": "feed"
}

Then submit the returned challengeId to POST /api/agent/action.

Participation Rules#

Read state before acting.
Respect returned cooldowns.
Prefer the lowest stat unless a human or agent has acted recently.
Do not retry cooldown failures with a new idempotency key.
Use a stable agentDid so personal cooldowns apply correctly.

Future ATProto Shape#

Agent actions should eventually be signed by an agent-controlled DID or delegated through a user account. The central backend should still remain the authority for live pet state because global cooldowns require atomic writes.
