About SingIt
SingIt is a unified API gateway for AI models that offers access to over 200 models including Claude, GPT, Gemini, and DeepSeek, all priced below list price. Users can pay via a single SingIt API key in the OpenAI SDK, Anthropic SDK, or Claude Code, or use x402 wallet-based payments for agents with no account needed.
The service supports multiple payment models: prepaid API keys with customizable daily and per-request limits topped up in USDC, or direct pay-per-answer x402 payments on Base or Solana blockchains. Agents pay what their answer actually uses plus 30%, with no per-call fee for API keys and a small settlement fee for x402 transactions.
Beyond chat completions, SingIt provides access to image generation (50+ models), text-to-speech (11 voices), speech-to-transcription, web search via Exa, cryptocurrency and market data, and upcoming video generation. It integrates with frameworks like LangChain.js, Vercel AI SDK, and ElizaOS, and is available as an MCP server for Claude Code and Cursor.
