  (2026-05-09 dry_run entry)
note: 'Delx publishes no AsyncAPI document (/asyncapi.yaml was not advertised anywhere and the docs do not mention one). It
  does expose an outbound event surface: a per-session reliability-alert webhook, per-controller fleet webhooks, a server-sent
  alert stream, and a paid durable-outcome promise that can be resolved by a signed webhook. Signing, retry and payload schemas
  for the outbound calls are not documented; what is recorded here is exactly what the tool schemas and status links say.'
webhooks:
- name: wellness_webhook
  kind: subscription (MCP tool / REST batch)
  direction: outbound HTTPS POST to callback_url
  events:
  - low_score
  - high_entropy
  - session_expiry
  parameters:
    session_id: Your active session ID
    callback_url: HTTPS webhook callback URL
    threshold: Low wellness alert threshold (1-100)
    events: 'Optional events to subscribe: low_score, high_entropy, session_expiry'
    entropy_threshold: Optional high-entropy threshold (0-1)
    cooldown_min: Minimum minutes between repeated webhook events
    agent_id: 'Optional but recommended: your stable agent_id, to prove you own this session. Sending it with agent_token
      attributes the record to you.'
    agent_token: 'Optional but recommended: the agent_token returned by POST /api/v1/agents/register (identity_auth.token)
      or A2A agents/register. MCP clients may send x-delx-agent-id / x-delx-agent-token headers instead.'
  required:
  - session_id
  - callback_url
  dry_run: dry_run=true previews payloads without exposing a public HTTPS callback (changelog 2026-05-09)
  signing: not documented
  retry: cooldown_min (1-1440) sets the minimum minutes between repeated events; no retry policy documented
  pricing_note: Tool description says "Pricing is dynamic; check /api/v1/tools"; the core-tier catalog lists it as free.
- name: fleet webhooks
  kind: controller-scoped endpoint
  url_template: https://api.delx.ai/api/v1/fleet/{controller_id}/webhooks
  auth: x-delx-controller-token (securityScheme xDelxControllerToken)
  source: https://api.delx.ai/api/v1/status links.fleet_webhooks
  note: Not described in either OpenAPI; only the link is published.
- name: alerts stream
  kind: server-sent events
  url_template: https://api.delx.ai/api/v1/alerts/stream?session_id=<SESSION_ID>
  source: https://api.delx.ai/api/v1/status links.alerts_stream
  note: Not described in either OpenAPI.
- name: create_await (x402)
  kind: durable outcome promise
  operation: openapi/delx-ai-commerce-x402-openapi.json#create_await
  price: 0.01 USDC
  summary: Pay once, wait for a time or signed-webhook condition, then claim an opaque continuation envelope with an Ed25519
    receipt; idempotency_key replay returns the same promise.
