TronEnergy API 需要身份认证吗？

无需 API 密钥，无需注册。每个请求通过对一条消息签名来认证，签名证明您是付款发送方。没有凭证，没有 API 密钥。

委托流程是怎样的？

向付款地址发送 TRX。对消息 {tx_hash}:{delegate_to} 签名以证明您是发送方。带上 tx_hash、delegate_to 和 signature 调用 POST /delegate。能量约 3 秒到账。

API 参考 | TronEnergy Docs

基础 URL： https://api.tronnrg.com 认证： 无需认证。所有端点均为公开。 速率限制： 每 IP 每秒 20 次请求 付款地址： TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx （仅限 API，不适用于手动租用）

工作流程

三个步骤。无需 API 密钥，无需注册，无需连接钱包。所有权通过加密方式证明。

发送 TRX — 向付款地址发送 4 TRX 或更多。4 TRX = 65,000 能量，8 TRX = 130,000。线性计价。
签名 — 用发送 TRX 的那个钱包对消息 {tx_hash}:{delegate_to} 签名，以此证明委托由您本人授权。
领取 — 调用 POST /delegate，附上 tx_hash、delegate_to 和 signature。能量约 3 秒到账。

付款地址

TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx

仅限 API 的付款地址。 该地址专用于通过 API 的编程集成。请勿用于手动能量租用。手动租用使用另一个地址，见。tronnrg.com.

向该地址发送 TRX。付款交易的哈希就是触发委托的凭证，每个哈希只能使用一次。

发送 TRX	委托能量	适用场景
4 TRX	65,000	向已有钱包的标准 USDT 转账（最低订单）
8 TRX	130,000	向首次收款方的 USDT 转账
16 TRX	260,000	一单覆盖四笔标准转账
40 TRX	650,000	十笔标准转账
100 TRX	1,625,000	约 25 笔标准转账 — 小型平台的常见规模
1,000 TRX	16,250,000	最高订单，约 250 笔标准转账
之间任意金额	`trx × 16,250`	完全线性。没有梯度，没有套餐，没有折扣。

公式： energy = trxSent × 16,250. 上下限： 最低 4 TRX（65,000 能量），最高 1,000 TRX（16,250,000 能量）。两者都在 API 层强制执行：低于最低值的金额会以 below_minimum 拒绝并退款；高于最高值的金额会在委托前被拒绝。在生产环境硬编码这些数值之前，请务必先从 GET /supply 读取实时值，见下文。

POST /delegate

POST/delegate

领取能量委托。您必须已经向付款地址在链上发送了 TRX。传入交易哈希、接收地址，以及证明您是付款方的签名。

参数	类型		说明
tx_hash	string	必填	TRX 付款的 64 位十六进制哈希
delegate_to	string	必填	接收能量的波场地址
signature	string	必填	用 tronWeb.trx.signMessageV2() 对 `tronWeb.trx.signMessageV2()` 的签名。证明您是付款发送方。

错误代码

每个错误响应都包含 error（机器可读、保持稳定）和 message（人类可读）。在代码中请始终以 error 作为分支条件。

代码	HTTP	含义
`invalid_tx_hash`	400	不是 64 位十六进制字符串
`invalid_address`	400	不是有效的波场地址
`missing_signature`	400	未提供签名
`invalid_signature`	401	签名无法验证
`signature_mismatch`	403	签名者地址与付款发送方不一致
`hash_already_used`	409	该交易哈希已被领取
`payment_verification_failed`	404 / 400	付款的链上验证失败。具体原因请读取 `message` 字段：交易暂未找到（404，几秒后重试）、收款方错误、不是 TRX 转账，或低于 4 TRX 最低额。
`delegation_failed`	400 / 500	供应方未能交付能量。如果失败发生在付款验证之后，退款会自动进入队列。出现此错误时请检查 `refund` 对象。
`rate_limited`	429	该 IP 每秒请求过多。上限为每秒 20 次。
`server_error`	500	意外的内部错误。请几秒后重试。

退款

如果付款验证后委托失败，TRX 退款会自动进入队列，在链上退回发送方地址。请查看错误响应中的 refund 对象。

带退款的错误

  "message": "Energy delegation failed. Your payment will be refunded.",
  "ref": "nrg_d_43",
  "refund": {
    "type": "queued",
    "to": "TSenderAddress",
    "amount": 4
  }
}
