The five tools
list_models: every model with its official input and output price, lowest channel and page. Filter by vendor or text.get_price: one model, every channel: region, pricing mode, cached and batch rates, tiers, announced changes, trust status, observation time, source snapshot.compare_channels: the same model across channels, sorted by input price, each with its difference from the official list price.cheapest: models ordered by their lowest input price on any channel, optionally by vendor or channel type.price_changes: observed changes between records and vendor-announced changes with effective dates.
Every answer ends with the same boundary the pages carry: list prices as published at the observed time, the channel's own page is authoritative, aggregator prices are never the reference, missing means unknown.
Without MCP
Plain HTTP, JSON back: https://auramatrix.ai/prices/v1/quote?model=openai/gpt-6.1-sol. Add &channel=azure-datazone-eu for one channel; model=list returns the ids. The whole dataset is at https://auramatrix.ai/prices/index.json, and a short guide for agents at https://auramatrix.ai/prices/v1/llms.txt.
What to expect
- Each record carries
trust_status: VERIFIED means a second person checked it against the source; UNVERIFIED means recorded, not yet checked. - Field names are stable, but the HTTP endpoint is not yet a frozen API version. A
v1with history and change events is planned; see Methodology.
