Does the TronEnergy API require authentication?

No API key or sign-up required. You authenticate each request by signing a message that proves you are the payment sender. No credentials, no API keys.

How does the delegation flow work?

Send TRX to the payment address. Sign the message {tx_hash}:{delegate_to} to prove you are the sender. Call POST /delegate with tx_hash, delegate_to, and signature. Energy arrives in ~3 seconds.

What happens if delegation fails after payment?

A TRX refund is automatically queued and sent back to the sender address on-chain.

Sanggunian API | TronEnergy Docs

Batayang URL: https://api.tronnrg.com Awtorisasyon: Hindi kinakailangan. Pampubliko ang lahat ng endpoint. Limitasyon sa singil: 20 kahilingan/segundo bawat IP Address ng pagbabayad: TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx ( API lamang, hindi para sa manu-manong pagrenta)

Paano Ito Gumagana

Tatlong hakbang. Walang API key, walang pag-sign-up, walang koneksyon sa wallet. Ang pagmamay-ari ay pinatutunayan sa pamamagitan ng cryptographic.

Ipadala TRX — Magpadala ng 4 TRX (o higit pa) sa address ng pagbabayad. 4 na TRX = 65,000 na enerhiya. 8 TRX = 130,000. Linear.
Karatula — Pirmahan ang mensahe {tx_hash}:{delegate_to} gamit ang wallet na nagpadala ng TRX . Pinapatunayan nito na awtorisado mo ang delegasyon.
Pag-angkin — POST /delegate kasama tx_hash, delegate_to, at signature. Energy ay darating sa loob ng ~3 segundo.

Address ng Pagbabayad

TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx

Address ng pagbabayad API lamang. Ang address na ito ay para sa mga programmatic integration sa pamamagitan ng API . Huwag gamitin ito para sa manu-manong pagrenta ng enerhiya. Iba ang manu-manong address ng pagrenta at makukuha ito sa .tronnrg.com.

Ipadala TRX sa address na ito. Ang transaction hash ng iyong bayad ang iyong token para ma-trigger ang delegation. Ang bawat hash ay maaari lamang gamitin nang isang beses.

Ipinadala TRX	Energy na Itinalaga	Kaso ng Paggamit
4 TRX	65,000	Karaniwang paglilipat ng USDT sa isang umiiral na wallet (minimum na order)
8 TRX	130,000	Paglilipat ng USDT sa isang unang beses na tatanggap
16 TRX	260,000	Apat na karaniwang paglilipat sa isang order
40 TRX	650,000	Sampung karaniwang paglilipat
100 TRX	1,625,000	~25 karaniwang paglilipat — karaniwan para sa maliliit na plataporma
1,000 TRX	16,250,000	Pinakamataas na order, ~250 karaniwang paglilipat
Anumang halaga sa pagitan	`trx × 16,250`	Ganap na linear. Walang mga tier, walang mga pakete, walang mga diskwento.

Pormula: energy = trxSent × 16,250. Mga Hangganan: min 4 TRX (65,000 enerhiya), max 1,000 TRX (16,250,000 enerhiya). Parehong ipinapatupad sa antas API — ang mga halagang mas mababa sa minimum ay tinatanggihan na may below_minimum at ibinabalik; ang mga halagang higit sa maximum ay tinatanggihan bago ang delegasyon. Palaging basahin ang mga live na halaga mula sa GET /supply bago i-hardcode ang mga ito sa produksyon — tingnan sa ibaba.

GET /supply

GET/supply

Kunin ang impormasyon sa presyo at ang address ng pagbabayad. Ito ay isang endpoint na nagbibigay ng impormasyon — ang enerhiya ay laging magagamit, hindi mo kailangang suriin bago ipadala ang bayad.

curl https://api.tronnrg.com/supply

const supply = await fetch('https://api.tronnrg.com/supply')
  .then(r => r.json());

// Energy is always available. Use supply.pay_to for the payment address.
console.log('Pay to:', supply.pay_to);

import requests

supply = requests.get('https://api.tronnrg.com/supply').json()

# Energy is always available. Use supply['pay_to'] for the payment address.
print(supply['pay_to'])

$supply = json_decode(
    file_get_contents('https://api.tronnrg.com/supply'),
    true
);

// if less than you require, wait and retry
// Energy is always available. Use $supply['pay_to'] for the payment address.
echo $supply['pay_to'];

var client = new HttpClient();
var json = await client.GetStringAsync("https://api.tronnrg.com/supply");
var supply = JsonSerializer.Deserialize<JsonElement>(json);

// Energy is always available. Use pay_to for the payment address.
var payTo = supply.GetProperty("pay_to").GetString();

POST /delegate

POST/delegate

Mag-claim ng energy delegation. Dapat ay naipadala mo na TRX sa payment address na on-chain. Ipasa ang transaction hash, ang address ng tatanggap, at isang lagda na nagpapatunay na ikaw ang nagpadala.

Parameter	Type		Description
tx_hash	string	required	64-karakter na hex hash ng bayad sa TRX
delegate_to	string	required	Tron address para makatanggap ng enerhiya
signature	string	required	Sign `{tx_hash}:{delegate_to}` using `tronWeb.trx.signMessageV2()`. Proves you are the payment sender.

Mga Error Code

Every error response has error (stable, machine-readable) and message (human-readable). Always switch on error.

Code	HTTP	Meaning
`invalid_tx_hash`	400	Hindi isang 64-karakter na hex string
`invalid_address`	400	Hindi wastong Tron address
`missing_signature`	400	Walang ibinigay na lagda
`invalid_signature`	401	Hindi ma-verify ang lagda
`signature_mismatch`	403	Hindi tugma ang address ng pumirma sa nagpadala ng bayad
`hash_already_used`	409	Na-claim na ang hash ng transaksyon
`payment_verification_failed`	404 / 400	On-chain verification of the payment failed. Read the `message` field for the specific cause: tx not found yet (404, retry in a few seconds), wrong recipient, not a TRX transfer, or below the 4 TRX minimum.
`delegation_failed`	400 / 500	Provider could not deliver energy. If the failure happened after the payment was verified, an automatic refund is queued. The error response includes a `refund` object when this happens.
`rate_limited`	429	Masyadong maraming request kada segundo mula sa IP na ito. Ang limitasyon ay 20/segundo.
`server_error`	500	Hindi inaasahang panloob na error. Subukan muli sa loob ng ilang segundo.

Refunds

Kung mabigo ang delegasyon pagkatapos ma-verify ang iyong bayad, awtomatikong ipipila ang TRX refund at ibabalik sa address ng nagpadala na nasa chain. Hanapin ang refund object sa error response.

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