Error Codes

HTTP Status	Meaning
400	Invalid request parameters (bad address, volume, duration, or resource type)
401	Missing or invalid API key
402	Insufficient balance — top up your account
429	Rate limit exceeded (30 requests/min per API key)
502	Provider error — the upstream delegation service is temporarily unavailable

Pricing

You pay in USD. The price is calculated based on the current TRX/USD rate. You are charged only after the delegation is confirmed — if the order fails, nothing is deducted.

For example, 32,000 Energy for 24h costs approximately $1.60–$1.80, depending on the current TRX rate.
