AI API Pricing Dataset

This dataset provides AI API model pricing data for cost estimation, LLM budget planning, and model price comparison.

Maintained, curated, machine-readable pricing data for major LLM and AI APIs. Prices change frequently, so production budget decisions should always be checked against the relevant provider pricing pages.

This repository publishes a versioned dataset and read-only static API for AI API pricing. It is designed for developers, SaaS builders, FinOps teams, researchers, technical writers, and AI systems that need maintained pricing records instead of ad hoc scraped snippets.

This project is maintained as an independent public dataset by AICostBudget. See aicostbudget.com.

Why this dataset?

• Source-linked pricing records
• Unknown or unverified values remain null, never 0
• Versioned JSON and CSV outputs
• Per-model history files
• Dated full snapshots
• Read-only static API
• Suitable for calculators, dashboards, cost analysis, and AI FinOps tooling

The weekly freshness workflow checks source URLs and stale last_verified_at values. It does not guess, infer, or overwrite prices automatically.

Fields

The CSV output uses the following fields:

Field	Meaning
provider_id	Stable provider identifier.
model_id	Stable model identifier within the provider.
display_name	Human-readable model name.
model_family	Model family or grouping when available.
status	Model availability or lifecycle status.
currency	Pricing currency.
unit	Pricing unit, such as per-token or per-million-token billing units.
input	Input token price for the listed unit.
output	Output token price for the listed unit.
cached_input	Cached input token price when available.
cache_write	Cache write price when available.
batch_input	Batch input token price when available.
batch_output	Batch output token price when available.
official_source_url	Provider page or document URL used for source checking.
accessed_at	Date when the source was accessed.
last_verified_at	Date when the record was last verified.
effective_from	Date when the listed pricing became effective, if known.
notes	Additional context or caveats for the record.

Data Freshness

Every model record includes:

• official_source_url
• accessed_at
• last_verified_at
• effective_from
• notes

Freshness checks are designed to surface stale source checks. Final billing decisions should still be verified against the provider's official pricing page, contract, and invoice.

API Reference

The static API is published through GitHub Pages:

• /api/v1/prices.json
• /api/v1/prices.csv
• /api/v1/meta.json
• /api/v1/providers/<provider>.json
• /api/v1/models/<provider>/<model>.json

Unknown or unverified prices are represented as null, never 0.

The CSV output includes normalized pricing fields for provider, model, pricing unit, source URL, verification dates, and notes.

Historical Pricing

Per-model history files are stored under:

data/history/<provider>/<model>.jsonl

Dated full snapshots are stored under:

data/snapshots/<YYYY-MM-DD>/prices.json
data/snapshots/<YYYY-MM-DD>/prices.csv

Methodology

Prices are accepted only from official provider pricing pages, official documentation, official APIs, or official announcements. Third-party calculators, SEO pages, Reddit posts, and competitor aggregators are not used as final price sources.
