Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

attestations Read-only

Free. Daily on-chain attestations of the fixing set. One record per store day: the keccak256 of the day's signed fixings file (served at /attest/<day>.json), the Ethereum Attestation Service UID and transaction on Base (eip155:8453), the publisher address and the schema UID. Re-hash the file bytes and compare with fixingsHash to verify; every row inside the file carries its own EIP-712 signature. See /governance.

azure_eviction

Paid (0.01 USDC per call). Azure spot eviction-rate history (28-day buckets, sampled daily). Daily samples of the eviction-rate bucket Azure reports per SKU (`0-5`, `5-10`, `10-15`, `15-20`, `20+` percent over the trailing 28 days). Collected daily since 2026-09-05; there is no history before the first sample.

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.

spot_daily

spot_events

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`.

read-only

Argument	Type	Description
az	string	Restrict to one availability zone / zone id (for example `use1-az1`). Default: all zones.
to	string	End of the window (exclusive), ISO 8601 UTC. Default: now.
from	string	Start of the window (inclusive), ISO 8601 UTC. Default: 7 days before `to`.
limit	integer	Maximum rows to return (1 to 10000). Default 5000.
region*	string	Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1
product	string	Restrict to one product / OS string (for example `Linux/UNIX`, `Spot`, `Linux`). Default: all.
instance*	string

spot_hourly

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.

read-only

Argument	Type	Description
to	string	End of the window (exclusive), ISO 8601 UTC. Default: now.
from	string	Start of the window (inclusive), ISO 8601 UTC. Default: 30 days before `to`.

spot_latest

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.

spot_monthly

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.

read-only

Argument	Type	Description
to	string	Last month (inclusive), YYYY-MM-DD. Default: latest.
from	string	First month (inclusive), YYYY-MM-DD (use the 1st). Default: earliest.
region*	string	Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1
instance*	string	Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
provider*	string

spot_snapshot

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.

read-only

Argument	Type	Description
region*	string	Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1

term

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.

term_instance

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).
