How this service works
corpusAI Cloud Pricing: One day's token price fixing for a ticker such as CX.TOK.CLAUDESONNET5.IN.
Output
Returns a JSON object with the ticker symbol, date, daily fixing value (value), number of observations (n), methodology description, optional high/low bounds, token side (IN/OUT/BLEND), basket member weights, and per-member input/output prices.
Example use cases
Daily LLM cost benchmark for budget planning
“Pull the latest daily token price fixing for frontier models using CX.TOK.FRONTIER.BLEND — I want to know today's blended rate and how many models are in the basket.”
Historical token price lookup for a specific model
“What was the blended input token price for the frontier model basket on 2024-06-01? Use the CX.TOK.FRONTIER.IN ticker and give me the value and methodology.”
Output token cost tracking for inference spend analysis
“Fetch the output token fixing price for today using the CX.TOK.FRONTIER.OUT ticker — I need the value, high, low, and basket composition to track our inference spend.”
Technical details
Endpoint
GEThttps://cloud.trycorpus.ai/v1/tokens/fixing?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, daily reference rate (fixing) for LLM token prices — particularly for frontier model blends — rather than scraping vendor pricing pages. It is ideal for cost benchmarking, budget forecasting, or building cost-aware AI agents that need to compare inference costs across models or track price changes over time.
Side effects
- Invalid or unrecognized ticker symbol returns an error
- Date out of available range (pre-data or future) returns no data
- Missing required 'ticker' query parameter causes a 400-style error
- x402 payment failure if USDC payment is not attached or insufficient
