Unified LLM API Gateway

TokSpan — short for "Token Span" — is a unified LLM API gateway and multi-LLM API router that bridges every major AI model to your application through a single OpenAI-compatible API. It serves as your:

• Model routing — switch models with one line of code
• OpenAI/Claude API proxy — drop-in compatible with any OpenAI SDK
• Multi-region model access — DeepSeek, Qwen, MiniMax, GLM, Kimi, and every Western frontier model through one endpoint

It handles routing, load balancing, rate limiting, cost tracking, and automatic failover — so you can focus on building instead of managing infrastructure.

Yes, absolutely. TokSpan exposes a fully OpenAI-compatible API — any library, SDK, or tool that works with OpenAI works out of the box:

• LangChain & LlamaIndex — drop-in compatible, zero config changes
• Vercel AI SDK & Next.js — access every model TokSpan routes through one endpoint
• OpenAI Python, Node.js, Go SDKs — no code changes needed

Just change the base URL to your TokSpan endpoint and you instantly unlock every supported model across every provider — with zero migration effort.

Unlike many API gateways that lock you into opaque pricing, TokSpan operates on a transparent pay-as-you-go model:

• Transparent per-token billing — direct provider cost plus a small, transparent service fee
• Full cost visibility on every request — see exactly what the upstream provider charges and our fee
• No hidden costs, no minimum commitments, no surprise bills
• Start free — create an account at no cost, explore the full model catalog, and pay only when you're ready

New accounts may receive promotional starter credits from time to time. Whether you need cost-effective Claude API access for prototyping or high-throughput DeepSeek V4 routing for production, pricing scales with you — transparently.

We never store your prompt or completion content. TokSpan proxies requests in real-time — your data passes through, it doesn't stay. Here's exactly what we do and don't do:

• We log: request metadata (timestamps, token counts, model IDs, status codes) — solely for billing accuracy and your usage dashboard
• We never log: prompt text, completion text, message content, or any payload body
• Encryption: API keys are encrypted at rest with AES-256; all data in transit uses TLS 1.3
• Your data, your control: we never use your data for training, never share it with third parties

If an upstream provider experiences an outage or returns errors, TokSpan's multi-LLM API router automatically retries and routes your request to your next preferred model based on your configurable fallback chain. Key benefits:

• No rate limit on failover traffic — your applications stay online, always
• Per-project fallback rules configurable in the dashboard
• Zero dropped requests, zero manual intervention

Yes. Many teams choose TokSpan as their OpenRouter alternative. Both platforms offer a unified OpenAI-compatible endpoint across hundreds of models. Where TokSpan differs:

• Transparent per-request billing — provider cost and service fee broken out separately on every call, not bundled into a single opaque rate
• Unified billing across every model — one prepaid balance, one invoice for all 200+ models
• No rate limits on paid tiers — scale to production throughput without artificial caps
• 15+ global edge nodes — sub-100ms latency from Asia, Europe, and the Americas

If transparent billing, flexible payment methods, and global edge routing matter for your stack, TokSpan is worth evaluating.

Yes — one endpoint covers every major Chinese foundation model alongside Western providers. No separate accounts:

• DeepSeek V4 & R1 — full API proxy access
• Qwen3.7-Max, Qwen3.7-Plus — the complete Qwen model family
• MiniMax, GLM, Kimi — all three available through a single TokSpan API key
• Auto-failover across providers — if any model is down, traffic routes to your backup automatically

No separate accounts, no per-provider signups. One API, every model — switch with a single line of code.

Absolutely — that's the core promise of TokSpan. With one API key for Claude and OpenAI (plus Google, Meta, DeepSeek, Qwen, MiniMax, GLM, Kimi, and 50+ other providers), you get a true unified Claude and GPT experience:

• No managing separate keys, billing accounts, or rate limits per provider
• Just change the model name in your request — TokSpan handles routing, auth, and billing
• Powerful for LangChain and Vercel AI SDK multi-model agent workflows

One key. Every model. Zero friction.

Yes. TokSpan's global edge network spans 15+ locations across Asia, Europe, and the Americas, with sub-100ms latency for most requests. Many developers start building within minutes — wherever they are.

• 15+ global edge locations — low-latency access from every major region
• One OpenAI-compatible endpoint — your existing SDK code works unchanged
• No separate accounts with individual providers

If you have questions about availability in a specific region, our support team is happy to help.

Getting started takes just a few minutes:

• Sign up with an email — create your account and generate an API key immediately
• Add credits — via credit card, PayPal, or bank transfer
• Top up what you need — no minimum deposit, no subscription

Start free, and scale when you're ready.

Yes. TokSpan is both a DeepSeek API alternative and a full DeepSeek API proxy:

• Route through our global edge network for low-latency DeepSeek access in your region
• Auto-failover to GPT-5.6 or Claude if DeepSeek experiences downtime — same model quality, lower latency
• Pay-as-you-go pricing keeps costs predictable — no per-token surprises, no minimum commitment

All through the same unified API — change one model name, ship your AI features. No code changes, no separate accounts.
