# R3CKON > R3CKON estimates the usage-phase environmental footprint of AI usage from token metadata (never content), always with stated uncertainty ranges, and retires third-party-issued environmental certificates (water restoration, carbon credits, renewable energy) against the conservative end (P90) of the estimate each month. It is an activity ledger, deliberately not a neutrality claim. By Tahosa Systems. ## Docs - [Overview](https://r3ckon.com/md/overview): What R3CKON does, who it is for, the core glossary, and what it deliberately is not. - [Quickstart](https://r3ckon.com/md/quickstart): From checkout to a working ledger in ten minutes. - [Connecting usage](https://r3ckon.com/md/connecting-usage): The three ingestion paths: managed provider connections (Anthropic, OpenAI, Google), the metering API, and self-report. - [Metering API reference](https://r3ckon.com/md/metering-api): Developer reference: authentication, ingest endpoints, event schema, the content boundary, and account APIs. - [Reading the console](https://r3ckon.com/md/console): How to read every element of the dashboard: P90 bars, whiskers, retirement strip, credit position, invoices. - [Certificates](https://r3ckon.com/md/certificates): The four-section certificate: anatomy, verification with supplier references, and the JSON document. - [Claims playbook](https://r3ckon.com/md/claims): What customers may say: approved statement families, why the banned list exists, required adjacencies, regulatory backdrop. - [Billing](https://r3ckon.com/md/billing): Tiers, billable tokens with worked examples, the certificate-share floor, cap behavior, subscription management. - [Security and data handling](https://r3ckon.com/md/security): Metadata-only architecture, credential encryption, payment handling, subprocessors, retention. ## Methodology - [Footprint Estimation Methodology](https://r3ckon.com/md/methodology): every constant with provenance and 90 percent ranges, the lognormal uncertainty math, correlated aggregation, deliberate choices, known unknowables, and inline citations. ## Everything at once - [llms-full.txt](https://r3ckon.com/llms-full.txt): all docs pages plus the full methodology, concatenated. ## Legal and policy - [Terms of Service](https://r3ckon.com/terms): including the generated claim schedules (approved language and required disclosures). - [AB 1305 disclosures](https://r3ckon.com/disclosures): voluntary carbon credit seller disclosures. - [Pricing](https://r3ckon.com/pricing): token-tier subscriptions with bundled retirements and the certificate-share floor. - [Mission and vision](https://r3ckon.com/mission): why neutrality cannot honestly be claimed today (provider data gaps, compute location opacity, non-local projects) and the conditional goals as data improves.
