Custody / RiskNot applicable

Overall = mean of Interrupt Score 98 and Machine-Readability 8893 / 100. The badge is set by the Interrupt Score alone — how scoring works.

Confidence: Provisional (0.55) — Based on Tier 0/1 evidence only (passive checks, no live transaction attempt) — treat the number as a triage signal, not a verified outcome.

This tool doesn't involve holding funds or assets, so custody risk doesn't apply.

Machine-Readability Score

Four check groups, equal weight: machine interfaces (OpenAPI, MCP server, llms.txt), browsing efficiency, element discoverability, and discovery/agent access (retrieval-bot robots.txt access, sitemap, schema.org). Each check is tagged with how strong the real-world evidence is that it changes agent behavior — proven, plausible, or emerging — grades are honesty labels, they never weight the score. A separate signal about ease of integration — it never enters the Interrupt Score or badge above.

88 / 100
Tier 2 not tested. No live signup/checkout attempt has run against this vendor yet — this is not the same as "no Tier 2 interrupts found." Either the vendor hasn't opted in to Tier 2 consent, or an automated ToS-ban/bot-prohibition signal structurally prevents Tier 2 from ever being attempted (see the findings below).

Interrupt tier: Low-Interrupt — derived from 1 finding; interrupt score 98 / 100. It alone drives the badge above; the headline Overall score blends it 50/50 with Machine-Readability.

Every tool starts at 100. Each interrupt found subtracts a penalty of base weight × timing × hardness × evidence — the multiplier values below come from the same rubric tables the score is computed with, so the arithmetic in this matrix reproduces the number exactly.

Interrupt Score = 100 − 1.6 = 98.4 → rounds to 9898

Score is in the 95–100 band, but the Zero-Interrupt badge additionally requires a completed live Tier-2 transaction and no hard-blocker finding — no live Tier-2 transaction has verified this flow end to end yet, so it is capped at Low-Interrupt.

Checked — nothing found

A check only turns green when a probe tier capable of detecting that interrupt actually ran and found nothing. Not tested ≠ clean.
