One API, the full launch set
Use Claude, GPT, Qwen, Doubao, Kimi, DeepSeek, GLM, and more through one OpenAI-compatible endpoint. Pick by task, price, context length, and language fit instead of wiring one vendor at a time.
Browse models →Why SeaLink
SeaLink focuses on one job: helping Southeast Asia developers use multiple AI models faster, with clearer billing and upstream handling.
Billing built for Southeast Asia
Top up by Stripe cards or local wallet payment links for GrabPay, PromptPay, TrueMoney, GoPay, and GCash, with Singapore billing for reconciliation.
See pricing →Five minutes to the first API call
Create an account, generate an API key, copy the dashboard curl, and make the first request. The same key works with common developer tools and OpenAI-compatible SDKs.
Read quickstart →Clear upstream path
SeaLink publishes availability for each launched upstream. API responses include headers for the upstream, requested model, served model, region, and fallback state.
View trust page →Local developer experience
English, Chinese, and Thai surfaces are built into the product. Model guidance is organized by real tasks: coding, support, translation, long documents, agents, and cost-sensitive workloads.
Compare models →Who SeaLink is for
If you build products in Singapore, Thailand, Indonesia, or Vietnam and need multiple models, reconcilable billing records, Chinese or Thai surfaces, tool guides, and a clear upstream path, SeaLink is designed for that workflow.
When you may not need SeaLink
If you only use one model vendor, already have stable contracts and invoicing, and do not need Southeast Asia localization, going direct may be simpler.
