    Description, as the server wrote it
    Paid (0.05 USDC per call). Daily USD per GPU-hour index per provider and market for one GPU model, with hyperscaler spot legs. For each snapshot day and (provider, market): number of quotes and the lowest, median, mean and highest USD per GPU-hour. Rows with provider `aws-spot` or `gcp-spot` are computed from our own spot price events for the instance family that carries the GPU (time-weighted daily bar divided by GPUs per node, per region), so the neo-cloud market and hyperscaler spot are comparable in one series. Quote history starts 2026-09-13; hyperscaler spot legs reach back to the start of our event data.

    Description, as the server wrote it
    Paid (0.05 USDC per call). Full daily history for one instance type, all eras stitched. One row per UTC day from the earliest data for the type to now. Rows dated before the type's first raw event come from the legacy history (`source` = `pauley`: measured 2022-05 to 2024-01 AWS, open/high/low/close present on days the price moved; `titans`: daily average only, 2024 to 2026). Rows from `direct_from` on are time-weighted, zone-collapsed bars from the raw event store (`source` = `direct`, same method as /spot/hourly; `avg` equals the public dashboard value). open/high/low/close are null where the source only has an average.

    Paid (0.05 USDC per call). Full monthly history for one instance type, back to 2014 for legacy AWS types. Calendar months from the earliest data to now. `months` is the curated series: `uscisi-adjusted` months (2017 to 2022-04, AWS types with a stable correction factor, average only), then months rolled up from the daily series (`pauley`, `titans`, `direct`: `avg` = median of daily averages, open/close from the first/last day, high/low the extremes, `days` = days covered, `source` = the source covering most days). `archive` (AWS, default on) is the USC/ISI monthly dataset 2014-02 to 2023-12 as published, with open/high/low/close, for 51 legacy types: third-party, mixes OS products, provenance partly unverified; returned separately so it never silently blends into the curated series.

    Description, as the server wrote it
    Paid (0.01 USDC per call). Reserved / reservation price history of one instance type (AWS standard RIs 1y/3y no-upfront/all-upfront; Azure reservations 1y/3y). Effective hourly USD with any upfront amortized over the term, as change-point series per `ri_type` (`ri_1y_no_upfront_standard`, `ri_1y_all_upfront_standard`, `ri_3y_no_upfront_standard`, `ri_3y_all_upfront_standard`; GCP `cud_1y`, `cud_3y`). AWS: Linux, shared tenancy, history back to 2016 for the original three regions, weekly refresh from the AWS Price List API. Azure: all-upfront reservations from the public Retail Prices API, daily, since 2026-09-13. GCP: resource-based committed-use discounts from the Cloud Billing Catalog (vCPU, RAM and GPU commitment SKUs), daily, since 2026-09-13.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Paid (0.01 USDC per call). Price currently in force per zone and product for one instance type. The most recent event of every (zone, product) series of the type, with its timestamp and age. A price is only meaningful while the provider still offers the type; AWS series older than ~10 days are likely retired, GCP/Azure reprice rarely so old timestamps are normal. For every type in a region at once use /spot/snapshot.

    Description, as the server wrote it
    Paid (0.05 USDC per call). Term structure per hyperscaler for one GPU model, USD per GPU-hour: spot, on-demand, 1y, 3y. For each hyperscaler with a mapped instance family (see /gpu/models hyperscaler_spot_legs), the median across regions of each term's price divided by GPUs per node, with lo/hi across regions and the discount to on-demand. Answers "what does a committed H100 cost against spot and on-demand, per cloud". Neo-cloud commitment prices are quote-only and excluded.

    Description, as the server wrote it
    Paid (0.01 USDC per call). Price ladder for one instance type: spot, on-demand, 1-year and 3-year commitments, with discounts. Current prices from our series: spot median across zones (where spot events exist), on-demand list price, and reserved/reservation terms as effective hourly with upfront amortized. `discount_pct` is relative to on-demand. AWS carries four reserved terms (1y/3y × no/all upfront), Azure two (1y/3y all upfront), GCP two resource-based committed-use terms (`cud_1y`, `cud_3y`, no upfront).

    Paid (0.01 USDC per call). One day's token price fixing for a ticker such as CX.TOK.CLAUDESONNET5.IN. Median across every source and host at the standard tier (batch and free variants excluded). `.IN` and `.OUT` are input and output USD per million tokens; `.BLEND` is (3·input + output) / 4. `CX.TOK.FRONTIER.<side>` is the median across the frontier basket listed by /tokens/models.

    Description, as the server wrote it
    Free. Every LLM with a token price fixing, its ticker codes and today's price range. Canonical model slugs (for example `claude-sonnet-5`, `gpt-6-astra`, `llama-4-maverick`), their ticker codes, how many sources and hosts list them, and the min/max input and output price seen today.

    Description, as the server wrote it
    Paid (0.10 USDC per call). Current price of every instance type, zone and product in a whole region, in one call. Bulk snapshot: the most recent event of every series in the region (about 6,000 rows for an AWS region), with timestamp and age per row. Same semantics as /spot/latest. Priced higher because one call returns the entire current price surface of the region.
