# Introduction (/)

The OpenGrid Data API gives you the GPU compute market as data: every price OpenGrid observes across cloud and
marketplace providers, the indices and fixings built from them, capacity, the full cost of a job, provider
reliability, market events and news.

Every request needs an API key. Every response says how fresh its data is.

## What you can get [#what-you-can-get]

| Area | What it answers | Start with |
| --- | --- | --- |
| Markets | What does an H100 cost right now, across every provider? | `GET /v1/markets` |
| Listings | Which exact offers exist, where, and are they in stock? | `GET /v1/listings` |
| History | How has that price moved over 24 hours, 90 days, or as far back as archives go? | `GET /v1/markets/{gpu}/history` |
| Indices and fixings | What is the reference price of a GPU, and can I verify it? | `GET /v1/indices`, `GET /v1/fixings` |
| Capacity | What do providers report as available? | `GET /v1/capacity` |
| Costs | What does a whole job cost, with egress and storage? | `POST /v1/costs/estimate` |
| Reliability | Is a provider's API up, and how fresh is its data? | `GET /v1/reliability/providers` |
| Events and news | What changed in the market, and what was reported? | `GET /v1/events`, `GET /v1/news` |

## How it works [#how-it-works]

OpenGrid polls each provider's own API or price list every 15 to 60 minutes. It maps every offer to a canonical
GPU, converts it to USD per GPU-hour, and checks it before publishing. Every row carries when it was observed, and
corrections are never silent.
