How this service works
Ranks models cheapest first by blended USD per 1M tokens (inputShare weights input vs output). Filter by provider, mode, minContextTokens, input/output modality, function calling, vision and price caps. Skips sample_spec and models past their deprecation date.
Output
A ranked list (cheapest first) of LLM models matching the specified filters, including blended USD price per 1M tokens, provider, model name, context window size, and supported modalities. Deprecated models and sample specs are excluded.
Example use cases
Budget model for high-volume chat app
“I'm building a chat app and need the 10 cheapest models available for chat mode — my traffic is roughly 70% input tokens and 30% output, so factor that in when ranking by price.”
Cheapest vision-capable model search
“Which LLM models support image input (vision) and are the cheapest? Give me the top 5, assuming my workload is split evenly between input and output tokens.”
Provider-specific cost comparison for embeddings
“Show me the cheapest embedding models available from OpenAI — I need at least a 8,192-token context window and want to see up to 10 results ranked by blended cost.”
Technical details
Endpoint
POSThttps://llm-model-price-table.x402supply.com/tools/find_cheapest_models?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically compare and rank LLM models by cost across multiple providers, especially when optimizing for a specific input/output token ratio, required capabilities (vision, function calling), or minimum context window. Prefer this over manually checking provider pricing pages or using a general-purpose search.
Side effects
- No models match the specified filters (overly restrictive combination of provider, mode, context window, and modality)
- Invalid provider ID returns empty results or error
- Payment not processed (x402 payment required, $0.005 USDC per call)
- minContextTokens set too high with no matching models
- Price cap too low to return any models
