Checkout flow not yet probed (Tier 2). For a transactional listing the purchase path is where interrupts actually bite — this readout reflects only what passive and signup-level checks could observe, not a verified purchase.

Capability parity

Each stage answers one question about what an agent can do unattended. Stages are ordered by the credential-gateway dependency: Activate issues the keys that unlock Operate and Manage. A row marked “Not yet probed” means no probe has tried that capability yet — a different ledger from the “unassessed” properties under Findings, where no probe tier capable of catching that interrupt has run.

Discover

Can an agent find and read it, no account?

Incomplete

Assessment incomplete - not yet probed: Read what it does and how to use it; Read pricing & limits without login.

Operate

Can an agent do the service's actual jobs — call, transact, pay?

Not yet probed

No probe has attempted this stage yet: Use the service's primary job; Complete a transaction / checkout; Pay via an agent rail (x402 / ACP / AP2).

Findings

How scoring works →

Interrupt tier: Low-Interrupt — no interrupts found; interrupt score 81 / 100 — the badge-driving metric. (range 50–100 · 8 unassessed)

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. New snapshots also provisionally subtract 50% of the full worst-case tax for each unassessed property and 25% for evidence-graded successes not live-verified by Tier 2.

Property coverage

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

No interrupts found — no evidence penalties. Unassessed properties still contribute a provisional tax.

How we scored this

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.
Machine-Readability sub-score: 35 / 100 (a separate integration-ease signal — it never enters the Interrupt Score or badge).
Some capability stages are not yet probed — shown plainly in the spine above, never as a pass.

Machine-readability checks 35 / 100

Four check groups, equal weight: machine interfaces, browsing efficiency, element discoverability, and discovery/agent access. Each check carries an evidence grade (proven / plausible / emerging) — an honesty label that never weights the score. What these mean →
