Capabilities
Listed exactly as the catalog flags them, including what this model does not support.
Vision
Natively multimodal: captioning, classification, visual Q&A, chart and screenshot understanding. Images are converted to tokens at the input rate.
Function Calling
Connect the model to external tools and APIs: it decides when to call which function and with what arguments, your code runs it. Force or forbid calls with tool_choice.
Reasoning
The model thinks before answering, which markedly improves multi-step planning and reasoning for coding, math and data analysis. Thinking tokens bill at the output rate.
Prompt Caching
Repeated prefixes (system prompts, long documents) hit the cache: reads cost far less than input, writes are priced by retention time.
Response Schema
Constrain output to a JSON Schema you provide for predictable, type-safe results without parsing free text.
Video
Video input understanding or video generation.
File Input
Upload PDFs and other documents directly; the model reads the whole document with native vision.
Streaming
Tokens arrive over SSE as they are generated; the first frame is forwarded immediately with no buffering. Claude Code, Codex and similar tools depend on this.
Web Search
Vendor-hosted live web retrieval; the model decides when to search and cites sources.
AudioNot supported
Audio input or speech output.
RealtimeNot supported
Bidirectional low-latency voice / text sessions over WebSocket.
SessionNot supported
Server-side multi-turn context (e.g. previous_response_id in Responses) so you need not resend history.
MediaNot supported
Image / video / music generation endpoints.
Multipart FormNot supported
multipart/form-data file-upload requests.
Binary ResponseNot supported
Endpoints that return raw audio / image bytes.
Protocols & code samples
Change the base URL to WandAPI, keep everything else. Native protocols pass straight through; “adapted” ones are translated by the gateway.
Anthropic SDK or any Messages-protocol client: point base_url at https://api.wandapi.com and use a WandAPI key.

}'Full price list
List price → WandAPI price per channel, every pricing dimension, nothing hidden.
| Item | Unit | Qwen list price | Qwen (Special Pricing) ×0.730% off |
|---|---|---|---|
| Input (prompt) | per 1M tokens | 1.4 Credits | |
| Output (completion) | per 1M tokens | 5.6 Credits | |
| Cache read | per 1M tokens | 0.28 Credits | |
| Cache write (general) | per 1M tokens | 1.75 Credits |
“Off” is computed at 1 Credit = ¥1 and today’s rate: 1 − channel multiplier × (1 Credit in the list currency). Standard (>256K): when input exceeds 256,000 tokens, billed at Cache read ×3、Output (completion) ×3、Input (prompt) ×3; stacks with any channel.
