Synap
OpenAI-compatible API for open models at near-cost prices
Synap (by Linkrra) is one OpenAI-compatible API for open-weight models. Point any OpenAI SDK at https://synap402.com/v1, change the base URL and key, and keep your code. Models we serve on our own GPUs include gpt-oss-20b ($0.017 in / $0.085 out per 1M tokens), Gemma 4 26B ($0.04 / $0.21) and Qwen3 Coder 30B ($0.0675 / $0.27). Keys from $10, top-ups never expire. You can try models in the browser without signing up.
Features
OpenAI-compatible endpoint: change base_url and key. Live per-model prices at synap402.com/models. Batch API at half price with a 24-hour window. Zero data retention, checked in code on every request. x402 top-ups in USDC on Base, from $1 to $1,000: the paying wallet is the account. Setup guides for Claude Code, Codex, Cline, Aider and more.
Use Cases
Send the routine calls from coding agents (Claude Code, Cline, Codex) to an open coding model. Run summaries, tagging and extraction on a small open model instead of a frontier one. Let an autonomous agent top up its own API credit in USDC, with no account. Push bulk jobs through the Batch API at half price.
Comments
Hi Fazier! We built Synap because most of what agents and coding tools send is small, repetitive work that does not need a frontier model. Synap is one OpenAI-compatible endpoint (https://synap402.com/v1) for open-weight models we run on our own GPUs: change base_url and key in any OpenAI SDK, Claude Code, Codex or Cline. Live prices per 1M tokens (in/out): gpt-oss-20b $0.017/$0.085, Qwen3 Coder 30B $0.0675/$0.27, Gemma 4 26B $0.04/$0.21. Batch is half price. Agents can also top up on their own in USDC over x402, no account. We would love feedback on which models you want next.
