How this service works
Pay-per-call tools for AI agents. USDC on Base or Solana via x402 v2; no keys, no accounts.
Output
A JSON object containing a list of LLM models, each with a model ID, input price in USD per 1 million tokens, and output price in USD per 1 million tokens, plus the pricing unit label.
Example use cases
Compare LLM costs before building
“I'm about to build an AI pipeline and I want to see what the input and output token prices are for all available models so I can pick the most cost-effective one.”
Find cheapest model for high-volume output
“Which LLM has the lowest output token price right now? I'm generating a lot of text and want to minimize costs.”
Filter pricing by specific provider
“Can you pull up all the pricing info for OpenAI models specifically? I want to see input and output costs per million tokens for each one.”
Technical details
Endpoint
GEThttps://api.gptshopltd.com/v1/prices/llm?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need current LLM token pricing data without API keys or account setup, especially in autonomous agent contexts where micropayment-based access (x402/USDC) is preferred over subscription APIs. Ideal for cost-comparison workflows or dynamic model selection based on price.
Side effects
- No models returned if filter query string matches nothing
- Stale pricing if the backend cache is not updated frequently
- Payment failure if USDC micropayment via x402 is not correctly submitted
- 400/402 errors if the x402 payment header is missing or malformed
