Common questions in one place. If yours isn't here, email support@sealink.asia — 30-min response window.
Getting started
How do I make my first call?
Sign up, copy the default API key from your dashboard, paste the cURL on the Quickstart page into your terminal. Should work in under 5 minutes.
Which model should I pick?
If unsure: deepseek-v4-pro for code, qwen3-max for SEA-language chat, deepseek-v4-flash for high-volume simple tasks. Or browse models by use case.
Is there a free trial?
Yes — $1 trial credit on signup, no card required. Enough for ~500 chat turns on deepseek-v4-flash.
Billing & invoices
Can you issue invoices?
Builder, Team, Creative, and Business plans get monthly Singapore billing records with custom headers and tax IDs where applicable.
What payment methods?
Visa / Mastercard / Amex via Stripe. GrabPay, PromptPay, TrueMoney, GoPay, and GCash through local wallet payment links.
Can I get a refund?
Unused balance refundable in full within 30 days. Subscription plans pro-rated. Consumed tokens not refundable.
API keys & limits
How do I rotate a leaked API key?
Dashboard → Keys → Rotate. A new key is issued immediately; the old key is revoked immediately and returns 401 on next use.
Can I limit a key's spend?
Yes — set a monthly budget per key. When the cap is hit, that key returns 402 until next month or you raise the cap.
What's the rate limit?
Per-account default 60 RPM. Higher tiers: Builder 300, Team 600, Business custom. Email support if you need more.
Account safety
What if my upstream account (Anthropic etc.) gets banned?
SeaLink manages provider credentials and routing internally, with fallback when a configured upstream degrades. Customer-facing availability is shown on /status.
Do you store my prompts and completions?
No. We log only metadata: model, token counts, latency, status. Request/response bodies are never persisted.
Where is data stored?
Singapore by default. Enterprise clients can discuss dedicated residency requirements during onboarding.
Tooling & integrations
Can I use SeaLink in Cursor?
Yes — SeaLink is OpenAI-compatible. See the Cursor integration guide; we provide a one-click config download.
Claude Code?
Yes, via two env vars. We offer an Anthropic-compatible endpoint that works directly with Claude Code.
Function calling? Vision? Caching?
All supported with OpenAI-standard syntax. See /docs/function-calling, /docs/vision, /docs/caching.
