OpenAPI 3.1
The whole contract — paths, parameters, response schemas — is published as /openapi.json, generated from the same module as this page, so the two can never drift apart.
curl -s https://aicomputetracker.com/openapi.jsonThree clocks, never conflated
The site keeps three independent freshness stamps, and each endpoint below names the one that owns it. Payloads additionally embed their own exact asOf / generatedAt stamps — trust those over any page-level date.

|---|---|---|---|
| Market snapshot | Forward curves, the terminal, and the market rail | The forward-market pipeline (Kalshi ladder snapshot) | |
| Live quotes | Automated quote rows and the observation ledger they feed | The weekly quote refresh plus the scheduled price-capture workflow | |
| Core data | Manual quote survey, hardware specs, financials, conventions | Manual survey sweeps (each one bumps the core-data stamp) |

| note (at note) | string | Payload-level honesty caveat: these are listed asks, not clearing prices, and absent chips are explicit gaps. |
| cadence (at cadence) | string | Intended capture cadence; scheduled runs can drift or skip, so missed hours are real gaps. |

Frontier buildout ledger
Core data ·
Provenanced ledger of frontier-scale AI datacenter sites: operator, location, accelerators, current and planned capacity, status, key dates — every figure traceable to a dated public source via per-site claims.

| est (at sites[].claims[].est) | boolean | True unless the figure comes from the operator's own announcement. |
- Best public estimates, not an audited census: capacity figures mix IT-load and campus-power conventions per underlying source — each claim names its basis.
- A null capacity is a real gap (no public figure), never zero.

DATA CONTRACT v1.1.0
The contract follows semantic versioning. Additive, backwards-compatible changes — a new field, a new endpoint — bump the minor version and never rename, remove, or re-type an existing field. Breaking changes — a renamed or removed field, changed units or semantics — bump the major version and are announced with a deprecation window during which the previous shape keeps being served. Documentation-only corrections bump the patch version.
Every JSON payload carries contractVersion and license at its root so a saved file stays self-describing. /price-history.json additionally keeps its own integer schemaVersion, which versions the ledger artifact itself and is never renamed.
