Frequently asked questionsWhat you need to know
How token pricing, technical compatibility, VAT invoices, and data handling work.
Does pricing include both input and output?
Claude and GPT bill (input + output tokens) × model rate. DeepSeek V4 Flash/Pro are flat $0.0105/$0.0118 per request; deepseek-v4-flash is $0.0682/1,000,000 tokens.
Does wallet balance expire?
No. Wallet balance never expires — use it until it runs out.
I use Claude Code / OpenClaw — do I need to change code?
No code changes. Set ANTHROPIC_BASE_URL to https://api.monkeytech.vn and ANTHROPIC_AUTH_TOKEN to your API key. Aliases fable, sonnet, and opus map to the matching 5-series models; unsupported names fall back to Fable 5 with header x-monkeytech-model-mapped-from.
Is there a rate limit?
No per-minute request cap on the API key.
Do you store my prompts?
We only store metadata: time, model, tokens, cost, latency, and status codes. Prompt and completion bodies are not written to the database.
What if I run out of balance mid-session?
The API returns HTTP 402. Top up and continue immediately — no key change needed.
