Overview
flatkey serves as a unified platform that consolidates access to over 100 official AI models and more than 1,000 pay-per-call tools under a single API key. This system intelligently routes requests to the most suitable model or tool based on the task, input, and scenario, aiming to optimize performance and cost. It eliminates the need for multiple subscriptions, duplicate API keys, or idle seats across various providers, streamlining AI integration and management for developers and enterprises.
The platform offers a comprehensive suite of functionalities, including text intelligence, image generation, and video generation, leveraging frontier models from labs like OpenAI, Anthropic, Google, and DeepSeek. Beyond model and tool routing, flatkey also operates a live GPU marketplace where AI companies can post compute requests and verified suppliers can bid, with flatkey managing escrow. This infrastructure ensures stability and reliability through a public 99.5% SLA, featuring automatic failover across five channel classes to maintain uptime even if an upstream channel degrades.
For enterprise users, flatkey provides robust governance features, including tree-structured sub-keys with budget caps and model allowlists. Every token processed is recorded in a per-request ledger API, ensuring auditability and transparency. Billing is consolidated into a single invoice for all successful calls, with failed calls incurring no cost. The platform is CLI-native and integrates with agent CLIs like Codex and Claude Code via SKILL.md, enabling agents to discover and utilize models and tools efficiently.
