Anthropic API — Claude API, self-serve signup and key issuance.
Verdict: Partially — an AI agent can use Anthropic API, 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
Can an agent find and read it, no account?

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.
- Call the primary service over MCP / APIEasy
Verified by a live call.
Gated by Activate — the credential this needs isn't issued unattended.

No agent-payment metadata detected - payment rails not yet probed.

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 2 findings; interrupt score 57 / 100 — the badge-driving metric. (range 26–76 · 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: 46 / 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 46 / 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 →
