Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to connect, but we couldn't read the tool list to see what that exposes. View diagnostics → Unverified
- HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the endpoint returned HTTP 530. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools.Unverified
Capabilities0
- Capabilities not yet verified: we couldn't read the endpoint's capabilities.Unverified
Unverified: 4 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

preflight x402 Preflight Trust Check ~162
One free call before your agent pays. Probes the URL (no wallet, payment, or auth) and returns a trust-preview.v1 verdict: liveness and latency, TLS validity, the 402 payment handshake with protocol detection (x402 v1/v2, MPP-capable), detected networks/asset/price with a USD estimate, ERC-8004 identity binding with Sybil-filtered reputation for the payee (which can adjust the recommendation), and a proceed / caution / avoid recommendation with human-readable reasons. Paid-tier fields (uptime history, reseller analysis) are present but null on the free tier.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Absolute https URL of the x402 or MPP payment endpoint to check |
