Why developers
build on SalpX.

Inspired by the salp: light, transparent, fluid and linked to one another. We turned that form into how an AI model API should work.

One API · every model

No rewriting code for every provider. SalpX is compatible with the OpenAI SDK: point base_url at SalpX and call Claude, Gemini, Qwen, DeepSeek, Kimi and more.

// just point base_url at SalpXimport OpenAI from "openai"; const ai = new OpenAI({  baseURL: "https://www.salpx.com/v1",  apiKey: process.env.SALPX_KEY,}); const r = await ai.chat.completions.create({  model: "claude-opus-4-8",  messages: [{ role: "user", content: "Hi" }],});

Smart routing

Each request goes to an available upstream route for the model you call.

Automatic retry

If an upstream call fails, SalpX retries it, switching routes when the model has more than one.

Pay as you go · no monthly fee

One balance and one bill across every model and key.

No subscriptionPer-key limitsOne bill

Available worldwide

Built for users outside mainland China. One endpoint and one account, wherever your business runs.

Encrypted in transit (TLS)

API traffic is encrypted in transit (TLS). We keep usage records (such as time, model and tokens) for billing, and your requests go to the model provider you choose.
