Example use cases

Cost optimization for production AI app

“I'm building a high-volume chat app and need to compare token prices across all major LLM providers — can you pull the latest pricing data and tell me which model gives the best cost per million tokens?”

Finding free-tier models for prototyping

“Which AI language models currently offer a free tier I can use for prototyping? Pull the latest LLM pricing data and show me all the ones with no-cost usage limits.”

Budget forecast for LLM usage

“I need to estimate monthly costs for running about 50 million tokens through an AI model — can you get the current pricing data for Claude, GPT-4o, and Gemini so I can compare?”

When to prefer

Choose this endpoint when you need a broad, multi-provider snapshot of LLM pricing and free tier availability in a single call, especially when building cost calculators, comparison tools, or budget forecasting features. Prefer this over scraping individual provider pricing pages, as it aggregates and normalizes data across providers with cited sources. Best used when you need structured JSON data ready for computation rather than a human-readable summary.

Side effects

Payment failure if USDC balance is insufficient or x402 payment flow fails
HTTP 402 returned if payment is not completed
Empty models or free_tiers arrays if data is temporarily unavailable
Stale pricing data if upstream model providers have changed prices recently
