At a glance
DeepSeek API provides function calling, JSON output and streaming output for developers integrating models; it is not a standalone agent that completes an end-to-end task. API input and output tokens are billed separately from consumer web access. JSON mode needs response_format=json_object and an explicit JSON instruction; handle truncation and possible empty content. Applications supply tool definitions, validate arguments and control execution: a tool request is not a completed action. With stream=true, assemble SSE deltas and inspect the finish reason. Check current models, account access, rates and limits in the official documentation. This is source-based guidance with unknown catalog scores, not an OKCodex model-run, speed, reliability or cost benchmark.

Review findings
This is a source review, not a measured task run. The recorded product/version does not identify an executed model. Manual publication alone does not establish hands-on testing; inspect benchmark runs for actual models, tasks and dates.
Based on public information: DeepSeek API is a developer-facing model API, not a standalone agent that can deliver complete tasks end to end. Task completion scores 3.5/5: it fits function calling, JSON output and SSE streaming inside your own app, but tool definitions, argument validation and execution control must be handled by the application. Output quality scores 3.5/5: OpenAI/Anthropic compatibility lowers migration cost, though JSON truncation and empty content need handling. Speed scores 4.0/5: stream=true returns incremental output via SSE, which can improve first-token experience, but no public latency measurements are provided. Chinese optimization scores 4.5/5, a relative strength. Value scores 4.0/5: token-based billing and broad SDK compatibility are solid, but exact rates and free quota must be checked against current official docs and the account. The upside is low integration friction plus streaming and structured output; the gap is that end-to-end task orchestration is not part of the API itself. tested_version: deepseek-flash.

Common questions
What pricing information is recorded for DeepSeek API?
The catalog lists paid pricing. Confirm current prices, included features and usage limits with the provider; this catalog does not verify a total cost or budget ceiling.
What do the catalog and review scores mean for DeepSeek API?
The catalog assessment is not recorded. The separate source-supported review records 3.9/5 for the product/version recorded in its source: deepseek-flash. This is a source review, not a measured task run. The recorded product/version does not identify an executed model. Manual publication alone does not establish hands-on testing; inspect benchmark runs for actual models, tasks and dates. It is automated source analysis, not a claim of hands-on human testing. The two score scales are not interchangeable.
