Tokker

The problem

AI token prices are hard to compare, because each API provider prices them differently and subscriptions hide their limits.

What it does

Tokker is a free, open price index that puts AI model APIs and subscriptions on one dollar scale.

How it works

1. Compares API prices per 1M tokens across about 60 providers, each number linked to its source and the date it was checked
2. Turns subscription limits (5-hour windows, weekly caps) into real tokens and $ per 1M at full use
3. Scheduled agents are planned to re-check every source and update a price when it moves

TodayThe price index at tokker.dev is public; the API code is merged but not deployed, and the index is from 5 Oct.

Aims

Autonomous operation

Keeping the prices true is the job that should run on its own: scheduled agents re-check every source, save the page as evidence, confirm a change with a second fetch and open a pull request, and small confirmed changes merge by themselves. A person reviews changes to limits, units or fair-use wording, and anything from a secondary source.

Intelligence

Mostly plain code: an extractor per source, the diff, the currency conversion and the token math that turns published limits into $ per 1M. A language model is only the fallback extractor, its output checked against the saved page and always sent to review.

Growth

Developer- and agent-led: a free JSON API and an MCP server, so coding agents can ask which provider is cheapest, and price-drop alerts by email. Free and open, with no affiliate links at launch. Growth is people and agents using the index, counted from the first API call that is not ours.
