Overall = mean of Interrupt Score 97 and Machine-Readability 78 → 88 / 100. The badge is set by the Interrupt Score alone — how scoring works.

Confidence: Verified (Probed) (0.95) — A live Tier-2 agent session completed the flow end to end.

Funds/assets pass through and are held by this vendor. A risk signal, not a friction signal — a tool can be Zero-Interrupt and custodial at the same time.

What your agent can do here

A plain-English read on the probe evidence — each verdict links to the finding behind it.

Can your agent sign up on its own?Signup inspected — no blocker found.
Can your agent read it without a human?Yes — machine-readable docs/API present.Machine-Readability 78/100
Can your agent self-serve credentials or a token?No provisioning blocker found.
Can your agent call it without a CAPTCHA?Yes — verified end-to-end, no transaction interrupt.

Agent-readiness: Yes — Fewsats can be used by an AI agent end-to-end without human intervention.

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.

Findings

How scoring works →

Interrupt tier: Zero-Interrupt — derived from 1 finding; interrupt score 97 / 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 found	Base weight	× Timing	× Hardness	× Evidence	= Penalty
Starting score					100
Mandatory redirect to vendor’s own sitePayment setupAccount creation + Stripe card linking via dashboard, one time.	4	×1one-time setup	×1soft	×0.8Tier 1 (unauth probe)	−3.2
Total penalty					−3.2
Interrupt Score = 100 − 3.2 = 96.8 → rounds to 97					97

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.
