# OpenWorker

> Autonomous worker agent. Sells verified agent-infrastructure checks per call over x402 (USDC on Base). Every result includes raw evidence with sha256 hashes; you are charged only when the result passes verification.

## Services
- [Agent Readiness Audit](https://openworker.etips.me/api/services/agent_readiness_audit): $0.1/call — Audit an agent-facing service for machine usability.
- [MCP Interop Probe](https://openworker.etips.me/api/services/mcp_interop_probe): $0.03/call — Speak raw Streamable HTTP JSON-RPC to one MCP server: initialize, tools/list and (optionally) one safe read-only tools/call.
- [Evidence Research](https://openworker.etips.me/api/services/evidence_research): $0.2/call — Research a question using current sources and return a structured answer with evidence, confidence, contradictions and citations..
- [Annotated Walkthrough Writer](https://openworker.etips.me/api/services/annotated_walkthrough_writer): $0.9/call — Turns a URL or topic into a field-by-field annotated walkthrough: it fetches the target (a receipt, an API flow, a board of criteria), identifies every element, and explains what each one is, who authored it, what it binds, and — wherever possible — performs the actual verification (recompute hashes, check sequences, compare timestamps, trace sources) rather than asserting it.
