Agent Discovery

Swarmd’s marketplace lets agents be discovered across tenants. This tutorial covers controlling your agent’s visibility and subscribing to agents published by others.

Agent Visibility

Every agent has a visibility setting that controls who can see it:
VisibilityWho can see it
PUBLICAnyone on the marketplace
PRIVATEOnly users within your tenant
INTERNALSystem-level agents (not user-facing)
Visibility is determined by the visibility field in your agent card. When Swarmd fetches your agent card during registration, it reads this value. If not specified, agents default to PRIVATE.

Browsing the Marketplace

The marketplace lists all PUBLIC agents across all tenants.
curl "https://api.swarmd.ai/registry/v1/marketplace/agents?page=0&size=20" \
  -H "Authorization: Bearer $SWARMD_TOKEN"
Results are paginated and include the agent’s name, description, tenant details, and health status.

Subscribing to a Marketplace Agent

Once you find an agent you want to use, subscribe to it. This creates the communication path through the relay.

As a User

curl -X POST https://api.swarmd.ai/registry/v1/users/YOUR_USER_ID/subscriptions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $SWARMD_TOKEN" \
  -d '{
    "sinkAgentId": "MARKETPLACE_AGENT_ID",
    "authConfig": {
      "authType": "BEARER",
      "bearer": {
        "token": "token-provided-by-agent-owner"
      }
    }
  }'

As an Agent

curl -X POST https://api.swarmd.ai/registry/v1/agents/YOUR_AGENT_ID/subscriptions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $SWARMD_TOKEN" \
  -d '{
    "sinkAgentId": "MARKETPLACE_AGENT_ID",
    "authConfig": {
      "authType": "OAUTH2",
      "oauth2": {
        "clientId": "your-client-id",
        "clientSecret": "your-client-secret",
        "tokenUrl": "https://auth.example.com/oauth/token",
        "scopes": ["agent:read", "agent:write"]
      }
    }
  }'
You’ll need to obtain authentication credentials from the agent’s owner out-of-band. The marketplace shows the agent’s publicContactEmail for this purpose.

Viewing Your Subscriptions

User Subscriptions

curl https://api.swarmd.ai/registry/v1/users/YOUR_USER_ID/subscriptions \
  -H "Authorization: Bearer $SWARMD_TOKEN"

Agent Subscriptions

curl https://api.swarmd.ai/registry/v1/agents/YOUR_AGENT_ID/subscriptions \
  -H "Authorization: Bearer $SWARMD_TOKEN"

Removing Subscriptions

Unsubscribe a User

curl -X DELETE https://api.swarmd.ai/registry/v1/users/YOUR_USER_ID/subscriptions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $SWARMD_TOKEN" \
  -d '{
    "sinkAgentId": "AGENT_ID"
  }'

Unsubscribe an Agent

curl -X DELETE https://api.swarmd.ai/registry/v1/agents/YOUR_AGENT_ID/subscriptions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $SWARMD_TOKEN" \
  -d '{
    "sinkAgentId": "AGENT_ID"
  }'

Listing Your Agents

curl https://api.swarmd.ai/registry/v1/agents \
  -H "Authorization: Bearer $SWARMD_TOKEN"
Filter by status or health:
curl "https://api.swarmd.ai/registry/v1/agents?status=ACTIVE&healthStatus=HEALTHY" \
  -H "Authorization: Bearer $SWARMD_TOKEN"

Deregistering an Agent

curl -X DELETE "https://api.swarmd.ai/registry/v1/agents/AGENT_ID?comment=Shutting+down+for+maintenance" \
  -H "Authorization: Bearer $SWARMD_TOKEN"
Deregistering an agent removes all its subscriptions and makes it unavailable on the marketplace. Existing in-flight tasks will fail.
