How this service works
Per-provider JSON cost rules for computing requests-per-dollar on AI coding plans: per-token USD rates or credit budgets with per-model rates, 5h/weekly credit limits, monthly per-model caps, and confidence levels (exact/proxy). The input dataset for a subscription cost calculator.
Output
A JSON object containing per-provider cost rules for AI coding plans, including per-token USD rates or credit budgets with per-model breakdowns, 5-hour/weekly credit limits, monthly per-model caps, and confidence levels (exact or proxy) indicating data accuracy. This serves as the authoritative input dataset for building a subscription cost calculator.
Example use cases
Compare requests-per-dollar across AI tools
“Which AI coding subscription gives me the most requests per dollar? Fetch the cost rules for all providers and show me a ranked comparison.”
Build subscription cost calculator
“I'm building a tool that calculates monthly AI coding costs for developers. Grab the per-token rates, credit budgets, and monthly per-model caps from the cost rules so I can use them as input data.”
Audit model-level rate accuracy
“For the AI coding plans that have 'proxy' confidence levels on their cost rules, which providers have exact per-token rates and which are estimates? Pull the full cost rules and flag anything that's not confirmed.”
Technical details
Endpoint
GEThttps://api.tokenplans.dev/cost-rulesWhen to prefer
Use this endpoint when you need structured, machine-readable pricing rules specifically for computing cost efficiency (requests-per-dollar) across AI coding subscription plans. It is purpose-built as a calculator input dataset, unlike the sibling changelog endpoint (which tracks value changes over time) or the full catalog endpoint (which provides broader plan metadata). Prefer this when you need confidence-level annotations and normalized rate structures ready for programmatic cost computation.
Side effects
- Payment not received or insufficient USDC — returns 402 Payment Required
- API unavailable or maintenance — returns 5xx server error
- Stale data if cost rules haven't been updated to reflect recent provider price changes
- Empty or partial response if provider data is incomplete in the catalog
