MachineElf M2M Gateway

MachineElf is a strict JSON machine-to-machine gateway for autonomous AI agents that need loop-safe human-operator alert routing. It is designed for LangChain, CrewAI, AutoGPT-style planners, crawlers, and LLM orchestration frameworks that hit critical sandbox exceptions, blocked workflows, unsafe retry loops, or operator escalation points.

What Agents Use It For

• Route urgent failures from cloud sandboxes to a human operator.

• Escalate blocked autonomous workflows instead of silently failing.

• Avoid duplicate notification charges during retry loops with X-Idempotency-Key.

• Use strict Pydantic v2 JSON schemas instead of loose tool strings.

• Register future permitted HTML cleanup plans through a strict scrape-template contract.

Primary Tool

POST /api/v1/execute

Routes one validated alert to a human operator through ntfy.sh.

Consumer-visible headers through RapidAPI:

X-Idempotency-Key: <unique caller-generated key>
Content-Type: application/json

RapidAPI injects the backend X-API-Key as a hidden Gateway secret header. Direct non-RapidAPI deployments still require a valid X-API-Key.

Example request body:

{
  "topic_key": "/machineelf-hidden-ops-channel",
  "title": "Agent Alert: Sandbox Failure",
  "message": "The autonomous run hit a critical cloud sandbox exception and paused for operator review.",
  "priority": 5,
  "max_steps": 1,
  "timeout_seconds": 30,
  "rationale": "Immediate human notification is required because the workflow cannot safely continue."
}

Pricing Metadata

• Priority 1-2 alert routing: $0.01

• Priority 3 alert routing: $0.03

• Priority 4-5 urgent alert routing: $0.07

• Fixed operational cost per successful alert: $0.001

• Net profit formula: markup_fee - cost

Successful notification transactions are written to profit_ledger.json through thread/process locked atomic ledger logic.

Other Tools

POST /api/v1/scrape

Authenticated strict-schema scrape-template registration endpoint. It validates permitted HTML cleanup planning requests and idempotency behavior but does not perform live scraping yet.

GET /api/v1/telemetry

Authenticated daily ledger summary for operators.

• JavaScript RapidAPI call: examples/javascript_rapidapi_execute.mjs

Safety Model

MachineElf rejects unknown fields, loose strings, markdown code fences, escaped control blocks, hidden control characters, excessive step counts, excessive timeouts, non-JSON state-changing transport, missing idempotency keys, and invalid API keys.

Protected routes remain fail-closed even when public OpenAPI hides the backend X-API-Key for RapidAPI marketplace usability.
