For developers and coding agents
DeepSeek API access for coding workflows
CodeUnlim offers prepaid access packages to the DeepSeek V4 Flash model through a managed API gateway. Choose the length of your package, a daily access window, and a reserved stream count.
What the service provides
The public model identifier is deepseek-v4-flash. DeepSeek V4 Flash has a maximum context window of 262,144 tokens. Input and generated output share that context; the gateway accepts output-token requests up to 65,536 tokens, while effective generation can be lower depending on input size and runtime behavior. The service supports API requests through its documented OpenAI Chat Completions and Anthropic Messages-compatible routes.
Compatibility describes request/response formats, not affiliation with or endorsement by OpenAI or Anthropic, and does not promise identical behavior across every client feature.
Packages, not token billing
Packages are sold for 1, 3, 7, or 30 days, with 4-, 8-, or 24-hour daily access windows and one, two, or three reserved streams. The customer accepts a local start time and IANA time zone when booking. A reserved stream is a package entitlement; it is not a guarantee that every request will decode simultaneously on a GPU.
When request demand exceeds the available execution capacity, requests may queue or be subject to runtime admission. No guaranteed tokens-per-second rate, zero-wait service, or service-level uptime commitment is made on this page.
Each purchase is a fixed-duration prepaid package. The current checkout creates non-auto-renewing access; a later package must be purchased separately.
API compatibility and integrations
Client configuration should use the CodeUnlim API base URL and the model identifier shown in the authenticated account setup instructions. The gateway exposes OpenAI-compatible chat completions and Anthropic-compatible messages routes. Client support for custom endpoints varies; compatibility is not a claim of official integration, certification, or complete feature parity.
OpenCode supports custom provider configuration for compatible APIs; customers must configure it as a custom provider and verify their chosen client settings. CodeUnlim is not affiliated with OpenCode. Likewise, Claude Code is an Anthropic product; use only client configuration paths supported by that product and do not infer support for features beyond the documented messages-compatible endpoint.
Getting started
- Choose a package in the booking calendar and check date/time availability.
- Review the tariff, daily window, time zone, duration, stream count, and total price.
- Complete authentication and payment through the available checkout method.
- Use the API key and endpoint details in your account dashboard.
Payment redirects alone do not confirm payment; fulfillment follows server-verified payment status. See the Terms, pricing catalog, and refund policy.
