How this service works
Calculates exact input, cached-input, and output token costs across frontier LLMs (OpenAI, Anthropic, Gemini, DeepSeek, Meta) and recommends optimal model routing.
Output
Returns a structured cost breakdown showing input token cost, cached-input token cost, and output token cost for each queried model, along with a recommended model routing decision based on cost-efficiency.
Example use cases
Budget-aware agent model selection
“I'm building an AI agent pipeline that processes thousands of documents daily — can you calculate token costs for Claude, GPT-4o, and DeepSeek and tell me which model to route to for the cheapest total spend?”
Cached prompt cost comparison
“My app reuses the same system prompt a lot, so cached-input pricing matters. What's the cost breakdown across Anthropic, OpenAI, and Gemini for a workload that's 80% cached input tokens?”
LLM spend forecasting for product team
“We're deciding which LLM to standardize on — can you pull the current token pricing for all the major frontier models (OpenAI, Anthropic, Gemini, Meta, DeepSeek) and recommend the most cost-efficient one for a mix of short inputs and long outputs?”
Technical details
Endpoint
GEThttps://canaryguard-402.onrender.com/v1/llm-token-pricing?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need accurate, up-to-date per-token cost comparisons across multiple frontier LLMs in a single call, especially when optimizing agent pipelines for cost or deciding on model routing strategies. Prefer it over manual lookup when you need cached-input pricing factored in or want an automated routing recommendation rather than just raw price tables.
Side effects
- Unknown or unsupported model name returns an error or null pricing
- Malformed request body missing required fields returns a 400-level error
- Stale pricing data if provider hasn't updated rates recently
- Rate or quota limits on the paid endpoint returning a 402 or 429
