Transparent data and calculation policy

Pricing data methodology

PayAPIKey publishes the sources, units, verification date, and formulas behind its AI model cost references. The calculator presets are starting points, not quotes or invoices.

Dataset verified: 50 official-source model records

How prices are selected

A model is included only when a first-party provider page states the model identifier and token rates clearly enough to normalize.

  • Use first-party model or pricing documentation as the primary source.
  • Store input, cached-input, and output prices separately in USD per one million tokens.
  • Record promotional end dates and note pricing rules the basic calculator does not model.
  • Keep every field editable because regions, long context, tools, media, batches, and negotiated terms can change the bill.

Current reference records

These values feed the AI Model Cost Calculator and the public JSON dataset. Follow the source link before relying on a value.

Calculation formulas

Monthly upstream token cost

requests × days × ((uncached input tokens × input rate + cached input tokens × cached rate + output tokens × output rate) ÷ 1,000,000)

Recommended monthly revenue

(upstream cost + platform cost) ÷ (1 − target net margin − payment fee rate − refund rate − bad-debt rate)

Machine-readable assets

Crawlers, analysts, and prospective buyers can inspect the same public inputs used by the interface.

Known limits

The reference does not automatically add every provider-specific charge. Tool calls, search, images, audio, video, cache writes, long-context premiums, batch discounts, regional processing, taxes, currency conversion, and contract pricing must be entered or reviewed separately.

Built as a transferable data asset

The source links, formulas, bilingual pages, machine-readable files, and deterministic update dates reduce diligence work for a future operator. PayAPIKey.com is available for acquisition.
