One API for chat, vision, image, video and voice.

Every model your key may use - chat, image, video and voice - with kind, capabilities, context_window and the client pricing. Works with both SDK families.

Fields: model, messages (system/user/assistant; user content may include image_url parts for vision), max_tokens, stream, tools + tool_choice (function calling - the model returns tool_calls, you run them and send role:"tool" results back), response_format (json_object / json_schema).

{
  "model": "WY Apex",
  "messages": [
    {"role": "system", "content": "You are our support assistant."},
    {"role": "user", "content": [
      {"type": "text", "text": "What is on this invoice?"},
      {"type": "image_url", "image_url": {"url": "data:image/png;base64,..."}}
    ]}
  ],
  "tools": [{"type": "function", "function": {"name": "lookup_order",
    "parameters": {"type": "object", "properties": {"id": {"type": "string"}}}}}],
  "max_tokens": 800
}

The Messages dialect: model, system, messages with text / image / tool_use / tool_result blocks, max_tokens, tools, stream. Responses use content[] blocks and stop_reason.

curl https://wyocs.org/v1/messages \
  -H "x-api-key: wyai_YOUR_KEY" -H "content-type: application/json" \
  -d '{"model":"WY Apex","max_tokens":512,
       "messages":[{"role":"user","content":"Draft a polite payment reminder."}]}'

Set "stream": true. Chat-completions streams chat.completion.chunk objects ending with [DONE]; Messages streams message_start → content_block_delta → message_stop events. The final chunk includes usage and your remaining balance.

curl https://wyocs.org/ai-api -H "Authorization: Bearer wyai_YOUR_KEY"
