Cerebras — Wafer-scale AI compute and inference.
Verdict: Partially — an AI agent can use Cerebras, but activate is blocked — A CAPTCHA blocks automated signup.

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

Operate
Can an agent do the service's actual jobs — call, transact, pay?
Assessment incomplete - not yet probed: Pay via an agent rail (x402 / ACP / AP2).
Gated by Activate — the credential this stage needs isn't issued unattended, so these rows may be unreachable even where they read Easy.

Verified by a live call.

Manage
Can an agent administer the account and provision resources?
No probe has attempted this stage yet: Provision / scale / tear down a service; Change account details / set budget / rotate keys; View usage & billing; Cancel / export / delete (offboard).
Gated by Activate — the credential this stage needs isn't issued unattended, so these rows may be unreachable even where they read Easy.

Findings
How scoring works →Interrupt tier: Moderate-Interrupt — derived from 1 finding; interrupt score 66 / 100 — the badge-driving metric. (range 35–85 · 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.

What would make this Easy
One concrete change per blocker found. These are the diffs between this listing's current parity and an unattended agent path.
- Activate — CAPTCHA / bot-challengeDrop the CAPTCHA, or gate it behind a documented bot-detection signal a well-behaved agent can pass.
How we scored this
- Confidence: Verified (Partial) (0.75) — A live Tier-2 session ran but stopped early at a detected hard blocker — verified up to that point, unknown beyond it.
- Machine-Readability sub-score: 38 / 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.
- Rubric, tiers, confidence model, and badge thresholds →
Machine-readability checks 38 / 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 →
