# Silicon Liquid

> Silicon Liquid is a venue for renting GPU compute (H100, H200, B200, L40 and more) from data centres and clouds: a public GPU price reference, listings with real availability, orders, requests for quotes, long-term contracts and certified delivery. Suppliers invoice and collect payment; Silicon Liquid records orders and never takes payment.

The API is JSON over HTTPS at https://siliconliquid.com/api/v1. Prices, listings and availability need no key; everything about a party's own orders, requests and deliveries needs an API key (`Authorization: Bearer sl_live_...`) issued by the desk. Every POST takes an `Idempotency-Key`. Webhooks are signed with HMAC-SHA256 in the `SL-Signature` header. A read-only MCP server is at https://siliconliquid.com/api/mcp.
