Everything you need to ship

Built for indie developers and small teams who want great models without juggling five vendor accounts.

🌐

One endpoint, many models

DeepSeek-V4 Flash, V4 Pro and Vision — routed through a single /v1/chat/completions URL. Switch models by changing one string.

🌱

Predictable pay-as-you-go

Per-token pricing in USD, visible spend on every key. Set hard quotas per token so a runaway script never surprises you.

🔒

Quotas & control

Every key carries its own budget, expiry and model allow-list. Revoke instantly from the dashboard — no support tickets.

Built for streaming

First-class SSE streaming support, long-context friendly timeouts and multi-provider failover behind the scenes.

📈

Transparent usage

Live dashboard of requests, tokens and spend per key. Export what you need for your own billing.

🤖

Drop-in compatible

Works with the OpenAI SDK, LangChain, LlamaIndex, curl — anything that speaks the OpenAI wire format.

Models & pricing

Per-million-token pricing. No subscriptions, no tiers, no minimum spend.

FAQ

How is this different from buying from the model vendors directly?

Three things: one consolidated invoice in USD, one key for every model, and quota controls per key. If you only ever need a single vendor's API, going direct is fine — this is for people who don't want five accounts, five payment methods and five dashboards.

What happens if a model goes down?

Traffic is routed through monitored channels with automatic failover. If a provider has an outage, affected models are disabled until recovered and your requests fail fast — you're never billed for failed calls.

Do you offer refunds?

Unused credit is refundable within 7 days of purchase. Consumed tokens are non-refundable, since we've already paid the upstream provider for them.

Is my data used for training?

No. We store request metadata (tokens, model, timestamps) for billing and abuse prevention for up to 30 days. Message content is not persisted beyond what's required for streaming the response.

Who is this service for?

Developers and teams located outside the Chinese mainland who want metered access to leading open-weight models. You are responsible for ensuring your use complies with the laws of your own jurisdiction.
