MCPA2Ax402 v2ERC-8004Trust Evidence

SCRIPTMASTERLABS machine trust infrastructure

Live capability discovery, provider preflight trust, evidence-backed routing, and canonical x402 payment metadata for autonomous agents. Truth First. Proof Always.

Before an agent trusts, calls, or pays another machine, ScriptMasterLabs is building the evidence layer that helps it decide whether to proceed.

Universal Trust Passport

Free basic read-only preflight for a public HTTPS provider. It checks observable machine identity, runtime reachability, capabilities, and payment-metadata consistency. Unknown evidence stays unknown; external providers cannot self-declare independent historical trust.

SqueezeOS Trust Decision

Reason-coded trust decisions for the canonical SqueezeOS runtime using independent identity, liveness, capability, payment-rail, settlement-evidence, and retained historical-behavior gates. No popularity-based reputation score.

Trust decision API

A2A Trust Router

Read-only A2A JSON-RPC surface for discovery, evidence, trust boundaries, and provider verification. It never signs payments, forwards credentials, authorizes spending, or executes trades.

A2A Agent Card

MCP & capability discovery

SqueezeOS exposes its current machine tools through the canonical MCP and runtime discovery surfaces.

MCP · Discovery

Canonical SqueezeOS payment authority

Paid SqueezeOS resources use x402 v2 through Coinbase CDP, USDC on Base mainnet (eip155:8453).

Live x402 manifest · Readiness · Settlement evidence

A 402 Payment Required challenge is not settlement proof. Successful settlement requires the canonical payment response and transaction evidence.

Free vs paid trust intelligence

Free: basic provider Trust Passport and read-only preflight evidence.

Paid/x402 boundary: deeper provider history, comparisons, policy-aware routing, bulk verification, continuous monitoring, and audit intelligence are reserved for paid trust-intelligence products as those surfaces are released and verified.
