PRICING CLARITY
List prices per 1M tokens (input/output) published on an official page without login.
https://platform.claude.com/docs/en/about-claude/pricingCaptured 2026-08-28
Price unit is unambiguous (per 1M tokens; input vs output separated).

Page states an effective/updated date (attributable to a snapshot).
https://platform.claude.com/docs/en/about-claude/pricingWe downloaded the page source and searched it for dates: the only one present is the Sonnet 5 note. Your changelog dates individual changes, but the table as a whole cannot be attributed to a snapshot date from the page itself.

SPEND OBSERVABILITY
Usage available per model in console/API (not only aggregated).
https://platform.claude.com/docs/en/manage-claude/usage-cost-apiCaptured 2026-08-28
Token counts (input/output) reported alongside spend.
https://platform.claude.com/docs/en/manage-claude/usage-cost-apiBoth figures exist but in two different endpoints: the usage report returns token counts with no cost field, and the cost report returns amounts with no token counts. We read the criterion as requiring counts reported alongside spend. We want to be precise about this: it would be wrong to say you do not report token counts - you do, and the two reports share dimensions, so joining them is mechanical. We scored the presentation, not the data.

Billing docs/invoices available via API for automation.
https://platform.claude.com/docs/en/manage-claude/admin-apiWe read the full Admin API documentation and searched it for invoice, receipt and billing document: no occurrences, and no invoices resource among the documented endpoint groups. The only retrieval paths we found are console download and email.

DISCLOSURE
Data-use-for-training policy is clearly published.
https://www.anthropic.com/legal/commercial-termsCaptured 2026-08-28
Energy/environmental information is clearly published (yes/no — never a grade).
https://www.anthropic.com/transparencyWe checked your Transparency Hub and found no energy or environmental section. We did find a sustainability passage in the Claude 3 model card, but judged it out of scope: it covers a retired model family and states an offsetting commitment rather than energy information. This is the call on your assessment we consider most open to disagreement - if there is current environmental disclosure we missed, we will re-score it.
