POSThttps://api.opennan.com/v1/finance/indicators

获取 API 密钥
在控制台创建密钥。它与试用区使用同一余额。
创建密钥

发送第一个请求

与试用区发送的请求相同。把 OPENNAN_KEY 设为你的密钥。

curl 'https://api.opennan.com/v1/finance/indicators' \
  -H 'Authorization: Bearer <OPENNAN_API_KEY>' \
  -H 'Content-Type: application/json' \
  --data '{"indicator":"sma","period":3,"candles":[{"time":"2026-01-01T00:00:00Z","open":100,"high":103,"low":98,"close":101,"volume":1050},{"time":"2026-01-02T00:00:00Z","open":103,"high":106,"low":101,"close":104,"volume":1100},{"time":"2026-01-03T00:00:00Z","open":102,"high":105,"low":100,"close":103,"volume":1150},{"time":"2026-01-04T00:00:00Z","open":108,"high":111,"low":106,"close":109,"volume":1200},{"time":"2026-01-05T00:00:00Z","open":105,"high":108,"low":103,"close":106,"volume":1250},{"time":"2026-01-06T00:00:00Z","open":110,"high":113,"low":108,"close":111,"volume":1300},{"time":"2026-01-07T00:00:00Z","open":109,"high":112,"low":107,"close":110,"volume":1350}]}'

读取结果
结果在同一个响应里返回。X-Usage-Cost-Usd 响应头写明本次调用的费用。

错误及解决方法

401缺少密钥或密钥错误
用 Authorization: Bearer 请求头发送控制台中的密钥。
402余额不足
在账单页面充值，然后重新发送同一请求。
400有值不被接受
查看 error.message，它会指出字段。请使用参数表中的值。
429请求过多
等几秒再试，每次遇到 429 都等得更久一些。
