# Green Compute > GPU compute on Bittensor subnet 110, powered by renewable and biogas energy. Rent RTX 4090 / RTX 5090 containers over SSH, billed per minute, or call open models through an OpenAI-compatible API. Everything is one HTTP API at https://api.green-compute.com with `Authorization: Bearer `. Key facts: - GPU rental: RTX 4090 $0.40/GPU-hour, RTX 5090 $0.70/GPU-hour, billed per minute while running, no deployment fee. Live prices: https://api.green-compute.com/platform/pricing (public, JSON). - Inference: OpenAI-compatible at https://api.green-compute.com/v1 (chat completions, streaming, tool calling). - A human creates the account, adds credit and creates the API key once at https://www.green-compute.com/settings. Everything else is API. - For agents: supply your own SSH public key in the workload's `metadata.ssh_public_keys`, and always DELETE the deployment when done. ## Docs - [Quickstart: rent a GPU with the API](https://www.green-compute.com/docs/quickstart.md): From an API key to an RTX 4090 you can SSH into, and back, in six HTTP calls. - [For AI agents](https://www.green-compute.com/docs/agents.md): Machine-readable entry points, what needs a human, and rules of thumb for agents using Green Compute. - [GPU rental reference](https://www.green-compute.com/docs/gpu-rental.md): Workloads, deployments, lifecycle, SSH, ports, disk, resume and RTX 5090 notes. - [Inference API (OpenAI-compatible)](https://www.green-compute.com/docs/inference.md): Chat completions, streaming, tool calling and reasoning models at api.green-compute.com/v1. - [Pricing](https://www.green-compute.com/docs/pricing.md): Per-minute GPU pricing, per-token inference pricing, and the live machine-readable price list. - [Errors and how to recover](https://www.green-compute.com/docs/errors.md): Every status code, what triggers it, and what to do next. ## API - [OpenAPI spec](https://api.green-compute.com/openapi.json): every endpoint and schema - [API index](https://api.green-compute.com/): links to everything below, no key needed - [Pricing (JSON)](https://api.green-compute.com/platform/pricing): what billing charges, no key needed - [Rentable GPU ids](https://api.green-compute.com/platform/nodes/supported): no key needed - [Free GPUs right now](https://control.green-compute.com/platform/v1/gpu-pool): no key needed ## Optional - [All docs in one file](https://www.green-compute.com/llms-full.txt) - [About Green Compute](https://www.green-compute.com/about)
