Free. Every index ticker, its segment and definition. Tickers are CX.<MODEL>.<SEGMENT> (for example CX.H100SXM.NEO) or CX.<MODEL>.SPOT.<REGION>. Includes the segment membership lists and the methodology version.

Free. Instance types available in a region. Exact type names with per-type coverage: raw events (`events`, `first_event`, `last_event`; zero/null for types that only exist in the legacy history) and legacy history ranges (`history_daily_from/to`, `history_monthly_from/to`). Optional `prefix` narrows the list (for example `c5.` or `n2-`).

Paid (0.01 USDC per call). On-demand list-price history of one instance type. Change-point series: one row per day the on-demand (pay-as-you-go) hourly list price changed; `current` is the price in force. AWS: Linux, shared tenancy, from the AWS Price List API, refreshed weekly, since 2024-01 (every AWS region in /catalog). Azure: every Linux VM SKU from the public Retail Prices API, refreshed daily, since 2026-09-13 (every Azure region in /catalog). GCP: the TITANS-era series (2024 to 2026-08), not refreshed.

Paid (0.10 USDC per call). Current on-demand list price of every instance type in a region.

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, dail…

Paid (0.10 USDC per call). Current reserved effective hourly price of every instance type and ri_type in a region (AWS or Azure).

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 th…

Paid (0.01 USDC per call). Raw spot price-change events for one instance type. Every price change for the type in the window, with exact timestamp, availability zone and product (OS). Sorted by time. Repeated identical prices are dropped by default (`include_repeats=true` keeps them). Up to `limit` rows; when `truncated` is true, continue with `from` = `next_from`.

Paid (0.01 USDC per call). Hourly time-weighted OHLC bars for one instance type. Per-zone series are bucketed by UTC hour with time weighting (a price counts for as long as it was in force), then collapsed across zones: open/close/avg are the median across zones, high is the max, low is the min. Window is capped at 366 days.

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.

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…

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.

Free. Freshness of every data source. Per source: last successful snapshot or event, staleness in days, and the public URL it is read from. Use it to decide whether a fixing or quote is current before paying for 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.

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 (0.10 USDC per call). Every model's input, output and blended fixing for one day, plus the frontier basket.

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.

Paid (0.05 USDC per call). Daily fixings for a token ticker, from the first snapshot (2026-09-14).

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. Also lists the frontier basket.

Paid (0.01 USDC per call). Every listed price for one model on one day: each source and hosting provider, USD per million tokens. Rows from the OpenRouter catalog, OpenRouter per-host endpoints (Azure, Amazon Bedrock, Google, Together, DeepInfra, …), the LiteLLM price table and DeepInfra. Includes cache-read price and context length where known; variants such as batch tiers are marked in `extra.variant`.
