TronEnergy API 需要身份验证吗？

无需 API 密钥或注册。您通过签署消息来验证每个请求，该消息证明您是付款发送方。无凭证，无 API 密钥。

委托流程如何运作？

将 TRX 发送到付款地址。签署消息 {tx_hash}:{delegate_to} 以证明您是发送方。使用 tx_hash、delegate_to 和签名调用 POST /delegate。能量在约 3 秒内到达。

Tron 能量租赁 API 参考:REST 端点与集成

基础 URL: https://api.tronnrg.com 身份验证: 无需验证。所有端点均为公开。 速率限制: 每 IP 每秒 20 个请求 支付地址: TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx (仅限 API,不适用于手动租赁)

工作原理

三个步骤。无需 API 密钥、无需注册、无需连接钱包。所有权通过密码学证明。

发送 TRX — 向支付地址发送 4 TRX（或更多）。4 TRX = 65,000 能量。8 TRX = 130,000。线性计价。
签名 — 使用发送 TRX 的钱包签署消息 {tx_hash}:{delegate_to}。这可证明您授权了能量委托。
领取 — 使用 POST /delegate 和 tx_hash、delegate_to 及 signature 领取能量。能量将在约 3 秒内到达。

支付地址

TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx

仅限 API 支付地址。 此地址用于通过 API 进行程序化集成。请勿用于手动能量租赁。手动租赁地址不同，可在上找到。tronnrg.com.

向此地址发送 TRX。您的支付交易哈希是触发能量委托的凭证。每个哈希只能使用一次。

发送的 TRX	委托的能量	使用场景
4 TRX	65,000	向现有钱包进行标准 USDT 转账（最小订单）
8 TRX	130,000	向首次收款人转账 USDT
16 TRX	260,000	一个订单内进行四笔标准转账
40 TRX	650,000	十笔标准转账
100 TRX	1,625,000	约 25 笔标准转账 — 小型平台常见
1,000 TRX	16,250,000	最大订单，约 250 笔标准转账
任何介于两者之间的金额	`trx × 16,250`	完全线性计价。无分级、无套餐、无折扣。

公式： energy = trxSent × 16,250. 限额： 最低 4 TRX（65,000 能量），最高 1,000 TRX（16,250,000 能量）。两者都在 API 级别强制执行 — 低于最低金额的订单会被拒绝并显示 below_minimum 并退款；超过最高金额的订单在委托前被拒绝。

POST /delegate

POST/delegate

申请能量委托。您必须已经向链上支付地址发送了TRX。请提供交易哈希、收款地址和证明您是发送者的签名。

参数	类型		描述
tx_hash	string	必需	TRX支付的64字符十六进制哈希
delegate_to	string	必需	接收能量的Tron地址
signature	string	必需	tronWeb.trx.signMessageV2()签名：`tronWeb.trx.signMessageV2()`。证明您是支付发送者。

错误代码

每个错误响应都有error（稳定、机器可读）和message（人类可读）。始终在代码中切换error。

代码	HTTP	含义
`invalid_tx_hash`	400	不是64字符的十六进制字符串
`invalid_address`	400	不是有效的Tron地址
`missing_signature`	400	未提供签名
`invalid_signature`	401	签名无法验证
`signature_mismatch`	403	签名人地址与支付发送者不匹配
`hash_already_used`	409	交易哈希已被认领
`payment_verification_failed`	404 / 400	链上支付验证失败。请阅读`message`字段了解具体原因：交易尚未找到（404，请稍后重试）、收款地址错误、不是TRX转账或低于4 TRX最低额。
`delegation_failed`	400 / 500	提供商无法交付能量。如果失败发生在支付验证后，将自动排队退款。此时请检查`refund`对象。
`rate_limited`	429	该IP的请求过于频繁。限制为每秒 20 次。
`server_error`	500	发生意外的内部错误。请在几秒钟后重试。
