API 使用指南

Chat 调用

普通文本、编码和文档提示可使用 TheRouter 的 OpenAI 兼容端点。除非确认会解析为 Anthropic 默认值，否则请省略 sampling 参数。

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"anthropic/claude-sonnet-5","messages":[{"role":"user","content":"Audit this migration plan for hidden production risks."}],"max_tokens":2000}'

工具调用代理

Sonnet 5 在能够规划、调用工具并验证结果时最强。请保持工具 schema 精简，并显式设置 effort 以获得可预测的延迟/成本。

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"anthropic/claude-sonnet-5","messages":[{"role":"user","content":"What is the order status for invoice INV-1042?"}],"tools":[{"type":"function","function":{"name":"lookup_invoice","description":"Look up invoice status by id","parameters":{"type":"object","properties":{"invoice_id":{"type":"string"}},"required":["invoice_id"]}}}],"tool_choice":"auto","reasoning_effort":"medium","max_tokens":1500}'

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
