API 状态码

API 状态码是服务器返回的代码，如 200、404、429、500、502。

​
API 错误代码

API 返回以下一组错误代码：
  • DefaultError = 1000,
  • FailedToBuildTransactionError = 1001,
  • NoQuoteError = 1002,
  • NotFoundError = 1003,
  • NotProcessableError = 1004,
  • RateLimitError = 1005,
  • ServerError = 1006,
  • SlippageError = 1007,
  • ThirdPartyError = 1008,
  • TimeoutError = 1009,
  • UnauthorizedError = 1010,
  • ValidationError = 1011,
  • RpcFailure = 1012,
  • MalformedSchema = 1013,

​
工具错误

除了返回状态和错误代码，API 可能会返回有关底层工具的错误消息，描述了特定工具的问题。这可能由许多原因引起，从工具简单地不支持所请求的代币对或流动性不足。 为了更好地解释失败案例，我们尝试以可预测的格式返回错误。ToolError 接口如下所示： 
type ToolErrorType = 'NO_QUOTE'

interface ToolError {
  errorType: ToolErrorType
  code: string
  action: Action
  tool: string
  message: string
}

​
可能的代码：

NO_POSSIBLE_ROUTE：没有找到此操作的路由。 INSUFFICIENT_LIQUIDITY：工具的流动性不足。 TOOL_TIMEOUT：第三方工具超时。 UNKNOWN_ERROR：发生未知错误。 RPC_ERROR：获取链上数据时出现问题。请稍后再试。 AMOUNT_TOO_LOW：使用此工具转移的初始金额太低。 AMOUNT_TOO_HIGH：使用此工具转移的初始金额太高。 FEES_HIGHER_THAN_AMOUNT：费用高于初始金额 — 这将导致负面的结果代币。 DIFFERENT_RECIPIENT_NOT_SUPPORTED：此工具不支持不同的接收地址。 TOOL_SPECIFIC_ERROR：第三方工具返回错误。 CANNOT_GUARANTEE_MIN_AMOUNT：工具不能保证会达到最小金额。
