Charter

Last reviewed: 26 October 2026. Rules 1 to 10 are the charter published with the price ledger on 20 October 2026. Their numbers and meaning are unchanged. Rules 11 to 14 extend the charter to the crawler archive and to licences.

InfraRabbit is a dated, sourced record of the AI economy: what AI costs (/prices) and what AI reads (/crawlers). These rules say what that means in practice.

The ten rules

  1. The provider is the truth. A price comes from the provider's own page or API. Community datasets (LiteLLM, OpenRouter, models.dev, gpuhunt) are cross-checks and are labelled as such wherever they appear. When they disagree with the provider, or with each other, the page shows both numbers and the difference. We do not quietly choose.
  2. Raw first, and immutable. Every observation starts as an unmodified, content-addressed copy of the source (URL, time, HTTP status, hash). Fields are derived from it and can be recomputed. The history is never rewritten. A correction is a new, dated fact.
  3. Gaps are shown. If a source fails, is blocked or looks wrong, its items say "not verified since <date>" and show no price. Nothing is interpolated. A change counts only once it is seen between two good runs. Copies from Wayback or Common Crawl are never treated as an observation of today.
  4. Nothing is for sale in the ranking. No affiliate links, no sponsored rows, no paid placement that touches order. Lists are sorted by provider and plan. "Cheapest" queries sort by price alone, and nothing else enters the sort key. If sponsorship ever exists, it will be labelled, kept separate and kept outside every table.
  5. Marketplaces are their own series. Asking prices, auction prices and spot prices are not list prices. They are never mixed into list-price series or indices.
  6. No language model in the measurement chain. Fetching, parsing, validation, diffing and index calculation are deterministic code. AI tools are used to repair parsers and add sources, but a model never produces a number that is published.
  7. Every number carries its evidence. Each price shows when it was last verified and links to its source. Each index value lists its constituents, each with its own verification time and source link. No page shows a number without a date and a source.
  8. Open for today and for citation, paid for access and volume. Current prices, every page and chart with its full history, the named index series (through the API and MCP too) and the change feed are free, under CC BY 4.0. Per-SKU history beyond 90 days through the API and MCP, bulk history exports and alerts are paid (Pro and Team). That is how this is funded. It never buys a position, a label or inclusion in any table or index.
  9. The methodology is public, including what we do not know. Each module has a methodology page that lists what it does not cover.
  10. Errors are corrected in the open. Write to corrections@infrarabbit.com. A report should name the item, the value you expect and a link to the source. A correction is a new dated entry. The original record stays visible and the correction is logged publicly with its date.

Rules for the crawler archive and for licences

  1. Observations, not accusations. The crawler archive records what a website's public files said on a date. It does not say what any crawler does, and it does not say a site broke a rule. A robots.txt file is a request.
  2. Unknown stays unknown. A site we cannot read is counted as unknown and shown next to every figure. Every share is shown with its denominator: "k of n", with bounds for the unknown.
  3. Owners can opt out. The owner of a website can have it excluded from the crawler archive by proving control of the domain. The exclusion is applied automatically. The number of excluded sites is published. See the FAQ.
  4. Licences stay honest. CC BY 4.0 covers our measurements only. Text from third parties, such as the robots.txt files we show as evidence, is not licensed. See the licence matrix.
