How this service works
OpenAI-compatible chat completion on deepseek-ai/DeepSeek-V4-Flash, served by DeepInfra (serverless inference) and sold by Taifoon at the provider's price plus a 3 % reseller cut: 0.0927 / 0.1854 USD per 1M tokens in/out. This request is priced at its prompt and max_tokens. The answer is checked before you are charged.
Output

Example use cases

“Use DeepSeek-V4-Flash to answer this user question in under 200 tokens: 'What are the main differences between supervised and unsupervised learning?'”
Draft a short marketing tagline
“Have DeepSeek-V4-Flash write three punchy one-line taglines for a fintech startup called 'LedgerLeap' that helps freelancers track invoices — keep the reply under 150 tokens.”
Classify sentiment of customer feedback

Technical details
Endpoint
POSThttps://coord.taifoon.dev/v1/chat/completions/deepseek-v4-flash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, cheap DeepSeek-V4-Flash inference through an OpenAI-compatible interface without managing your own API keys or self-hosted infrastructure, especially in agentic pipelines that already support x402 micropayment headers. It is well-suited for short-to-medium completions (max 700 tokens output) where per-call pay-as-you-go pricing at ~$0.001 is preferable to subscription-based alternatives. Prefer it over the generic multi-model Taifoon endpoint when you specifically want DeepSeek-V4-Flash semantics and pricing.
Side effects
- Exceeds max_tokens cap of 700 — request rejected or truncated
- Invalid or unsupported model string — falls back to default model or returns error
- messages array empty or missing required role/content fields — 422 validation error
- Payment failure via x402 — charge not completed, no response returned
- Rate limit or DeepInfra backend unavailability — 503 or timeout
- Context too long for model's window — upstream inference error
