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.

Marejeleo API | TronEnergy Docs

URL ya Msingi: https://api.tronnrg.com Idhini: Hakuna kinachohitajika. Sehemu zote za mwisho ni za umma. Kikomo cha kiwango: Maombi 20 kwa sekunde kwa kila IP Anwani ya malipo: TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx ( API pekee, si kwa ajili ya kukodisha kwa mikono)

Jinsi Inavyofanya Kazi

Hatua tatu. Hakuna ufunguo API , hakuna usajili, hakuna muunganisho wa pochi. Umiliki unathibitishwa kwa njia ya siri.

Tuma TRX — Tuma TRX 4 (au zaidi) kwa anwani ya malipo. TRX 4 = nishati 65,000. TRX 8 = 130,000. Mstari.
Ishara — Saini ujumbe {tx_hash}:{delegate_to} kwa kutumia pochi iliyotuma TRX . Hii inathibitisha kwamba uliidhinisha uwasilishaji.
Dai — POST /delegate na tx_hash, delegate_tona signatureEnergy hufika baada ya sekunde ~3.

Anwani ya Malipo

TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx

Anwani ya malipo API pekee. Anwani hii ni ya ujumuishaji wa programu kupitia API . Usitumie hii kwa ukodishaji wa nishati kwa mikono. Anwani ya ukodishaji kwa mikono ni tofauti na inapatikana kwenye .tronnrg.com.

Tuma TRX kwa anwani hii. Hashi ya muamala wa malipo yako ni tokeni yako ya kuanzisha ugawaji. Kila hashi inaweza kutumika mara moja tu.

TRX Imetumwa	Energy Imekabidhiwa	Tumia Kipochi
4 TRX	65,000	Uhamisho wa kawaida USDT hadi kwenye pochi iliyopo (kiasi cha chini cha agizo)
8 TRX	130,000	Uhamisho wa USDT kwa mpokeaji wa mara ya kwanza
16 TRX	260,000	Uhamisho wa kawaida nne katika mpangilio mmoja
40 TRX	650,000	Uhamisho kumi wa kawaida
100 TRX	1,625,000	~Uhamisho wa kawaida 25 — kawaida kwa mifumo midogo
1,000 TRX	16,250,000	Agizo la juu zaidi, uhamisho wa kawaida wa ~250
Kiasi chochote kati ya	`trx × 16,250`	Kikamilifu mstari. Hakuna ngazi, hakuna vifurushi, hakuna punguzo.

Fomula: energy = trxSent × 16,250. Mipaka: Kiwango cha chini cha 4 TRX (nishati 65,000), kiwango cha juu cha 1,000 TRX (nishati 16,250,000). Zote mbili zinatekelezwa katika kiwango API — kiasi kilicho chini ya kiwango cha chini kinakataliwa kwa kiwango cha chini cha chini na kurejeshewa pesa; kiasi kilicho juu ya kiwango cha juu kinakataliwa kabla ya kugawa. Soma kila wakati thamani za moja kwa moja kutoka kwa GET /supply kabla ya kuziweka kwenye mfumo wa uandishi — tazama hapa chini.

GET /supply

GET/supply

Misimbo ya Hitilafu

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

Code	HTTP	Meaning
`invalid_tx_hash`	400	Sio mfuatano wa heksadi wenye herufi 64
`invalid_address`	400	Sio anwani halali Tron
`missing_signature`	400	Hakuna sahihi iliyotolewa
`invalid_signature`	401	Saini haikuweza kuthibitishwa
`signature_mismatch`	403	Anwani ya mwenye kusaini hailingani na mtumaji wa malipo
`hash_already_used`	409	Hash ya muamala tayari imedaiwa
`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	Maombi mengi sana kwa sekunde kutoka kwa IP hii. Kikomo ni 20/sekunde.
`server_error`	500	Hitilafu ya ndani isiyotarajiwa. Jaribu tena baada ya sekunde chache.

Refunds

Ikiwa ugawaji utashindwa baada ya malipo yako kuthibitishwa, marejesho TRX huwekwa kwenye foleni kiotomatiki na kutumwa kwa anwani ya mtumaji iliyopo kwenye mnyororo. Tafuta kitu cha marejesho katika jibu la hitilafu.
