Three ways to connect
- MCP server: https://app.singitai.app/mcp. Free tools are keyless; paid tools need an API key.
- OpenAI-compatible endpoint: with a SingIt API key, use https://app.singitai.app/v1 (see Developers). For x402 pay-per-call, use https://ask.singitai.app/v1: no key; a wallet pays for paid calls.
- x402 SDKs: use the repository recipes for wallet-funded requests.
The model snippets below were run on 31 October 2026 in Prague, with Node 24.22.1 / Python 3.13.5, against the x402 host's free route, model free/deepseek-v4.1-flash, with a dummy API key and no payment. Each returned “pong”. This verifies client wiring: the base URL, model ID and response shape. The MCP snippets listed 16 tools on the real server, keyless.
Not tested: the SingIt API-key variant. Change only the base URL setting (base_url, baseURL, or LiteLLM's api_base) to https://app.singitai.app/v1 and the API key setting to your SingIt key. That exact variant was not run; no SingIt key was used.
Not tested: paid x402 payment from these libraries. It needs a funded wallet; follow the existing recipes below.
