How this service works
Every model on the OpenRouter marketplace with per-million-token input and output pricing, cached-input rates where published, and context windows: several hundred rows, rebuilt daily. Each build carries a changes block diffing it against the previous published build, listing models added, models the marketplace dropped with their last known figures, and every price or context-window movement as from/to. Spot repricing without re-reading 400 unchanged rows.
Output
A tabular dataset of several hundred rows — one per OpenRouter model — each containing the model name/ID, per-MTok input price, per-MTok output price, cached-input rate (where published), and context window size. Data is refreshed daily.
Example use cases
Budget model selection for startup
“What are all the models currently on OpenRouter and what do they cost per million tokens for input and output? I need to find affordable options for my app.”
Cached-input rate comparison
“Which OpenRouter models publish cached-input pricing, and what are those rates compared to their standard input cost?”
Context window survey for long-doc use case
“Give me a ranked list of all OpenRouter models by context window size so I can figure out which ones can handle long documents.”
Technical details
Endpoint
GEThttps://datastand.dev/api/data/llm-catalogWhen to prefer
Use this endpoint when you need breadth — a full enumeration of every model available on OpenRouter with current pricing. Prefer this over the llm-pricing sibling endpoint when you want to discover what models exist and survey the cost landscape, rather than needing vendor-verified provenance for a specific model's price. Ideal for cost comparison pipelines, model selection tools, or any workflow that needs to enumerate the full OpenRouter catalog programmatically.
Side effects
- Stale data if daily refresh has not yet completed
- Missing cached-input rates for models that do not publish them
- HTTP 402 if payment of 0.02 USDC is not included
- Rate limiting or access errors if x402 payment fails
- Incomplete rows if OpenRouter marketplace metadata is missing for a model
