Modal — Serverless GPU/compute platform, self-serve signup.

71 / 100triageInterrupt Score(range 40–90 · 10 properties unassessed)How much automated use this service interrupts — the badge-driving metric. Unassessed properties are provisionally scored at 50%; evidence-graded successes at 25%.

Custody / RiskUnknown

ConfidenceProvisional

Verdict: Partially — an AI agent can use Modal, but activate is blocked — SSO-only signup, no API-key path and manage is blocked — SSO-only — no admin API path.

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.

Operate

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

Findings

How scoring works →

Interrupt tier: Moderate-Interrupt — derived from 1 finding; interrupt score 71 / 100 — the badge-driving metric. (range 40–90 · 10 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.

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: 29 / 100 (a separate integration-ease signal — it never enters the Interrupt Score or badge).
Some capability stages are not yet assessed — shown plainly in the spine above, never as a pass.

Machine-readability checks 29 / 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 →
