Cheap H100 GPUs, rented by API
Lium is a GPU rental marketplace where providers set their own prices. You can find an H100, rent it, run a job and remove it from the REST API, the lium CLI or the Python SDK, and you pay per second while it runs.
H100: from $2.00 per GPU-hour, 64 free right now. Live H100 prices
Find the cheapest H100, rent it for at most an hour, run a command, remove it
pip install lium.io export LIUM_API_KEY=sk_... lium ls --gpu H100 --format json # cheapest first; pick a node id lium up <node-id> --yes --no-ssh --ttl 1h --name h100-job lium exec h100-job "nvidia-smi" lium rm h100-job
Prices you can read before you sign up
Every listed node and its price is public: lium.io/pricing.json has one row per GPU model with the live price range, and lium.io/api/public/v1/nodes lists each node. Neither needs an API key.
Providers set their own prices, so the same GPU can be listed at several prices. The price on this page is the lowest one rentable when the page was built.
The API
The REST API is described by a live OpenAPI 3.1 schema at lium.io/api/openapi.json. Requests carry your key in the X-API-Key header, and errors return a stable error code with a hint.
A rent request accepts an Idempotency-Key header, so a retried request does not rent a second pod.
Frequently asked questions
Is an H100 always available?
No. H100s are rented from independent providers, so at times none is free. The live line on this page says how many are free right now; lium ls --gpu H100 shows the current nodes.
How is a pod billed?
Every pod has an hourly price and is billed per second, with no minimum rental period. Billing stops when the pod is removed. A pod rented with --ttl removes itself when the time is up.
Can an AI agent do this without a browser?
Yes. Signup, API keys, renting, running commands and removal all work from the CLI or the REST API with no browser and no e-mail confirmation. docs.lium.io/developers/agents is the one-page guide.
