name: trust402.aztecbeacon.uk
description: trust402.aztecbeacon.uk provides a single evaluation service that inspects a web origin's x402 payment and discoverability configuration, returning a structured trust score, risk level, and per-check breakdown. It is designed to help agents determine whether a domain is properly set up for x402 interactions before routing users or payments to it. It does not perform transactions, price lookups, or endpoint-level API testing.

# trust402.aztecbeacon.uk

This host serves as a pre-flight trust checker for x402-enabled web origins. It targets agents that need to vet third-party domains before initiating payment flows or referrals, checking for signals like OpenAPI documentation, .well-known/x402 presence, pricing metadata, and agent guidance files. It occupies a narrow, specific role in the x402 ecosystem: origin-level due diligence, not execution.

## When to use this host

Use this host when an agent needs to vet an unknown or third-party web origin before interacting with it in an x402 context — for example, before routing a user to a payment endpoint or integrating a new merchant. It is not suitable for real-time token pricing, individual API endpoint validation, transaction execution, or any form of market data lookup. If you need price feeds or trade execution, route to a dedicated DeFi or market-data host instead. This host has exactly one skill and no composable workflows; it is a single-purpose trust gate.

## Capabilities

### Origin Trust Evaluation

Assesses a web origin's x402 discoverability posture by checking for required configuration signals and returning a trust score, risk level, and actionable recommendation.

- **`evaluate-origin-trust`** — Evaluates the x402 discovery posture of a web origin and returns a trust score, risk level, recommendation, and per-check breakdown of missing discoverability signals.

## Skill reference

### `evaluate-origin-trust`

**Trust Origin Check** — Evaluates the x402 discovery posture of a web origin and returns a trust score, risk level, recommendation, and per-check breakdown of missing discoverability signals.

*Use when:* Use when an agent needs to assess whether a web origin is trustworthy and properly configured for x402 payments before interacting with or routing users to it, especially when checking for OpenAPI docs, .well-known/x402, pricing metadata, and agent guidance.

*Not for:* Do not use for evaluating individual API endpoints in isolation; this tool assesses the full origin/domain posture. Not suitable for real-time price feeds or token lookups.

**Inputs:**

- `endpoint` (string) — Full URI of a specific paid endpoint at the origin to include in the evaluation.
- `origin` (string) — Base URI of the origin/domain to evaluate for x402 discovery posture.
- `priceUsd` (number) — Known price in USD for the endpoint, if available, to include in scoring context.
- `hasInputSchema` (boolean) — Whether the endpoint is known to expose an input schema.
- `hasOpenApi` (boolean) — Whether the origin is known to expose an OpenAPI document.
- `hasWellKnown` (boolean) — Whether the origin is known to expose a .well-known/x402 document.

**Returns:** Returns ok=true with a numeric score (e.g. 18/100), riskLevel (e.g. high), recommendation (e.g. avoid-until-fixed), a checks array with per-signal pass/fail results, a missing list, context counts, nextSteps, and raw discovery objects.

**Example:** `{"origin": "https://shop1.trust402.example.org"}`
