# TRON TRC-20 Energy and Bandwidth Cost Budgeting

> TRON TRC-20 Energy and Bandwidth Cost Budgeting is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-18).

Returns a deterministic pre-payment cost estimate in TRX and USD for a TRON TRC-20 transfer, accounting for free bandwidth allowance, energy costs, and TRX burn.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tron-trc-20-energy-and-bandwidth-cost-budgeting-856f38b0
```

Example prompt: Before I send 500 USDT via TRC-20, can you estimate the full transfer cost in TRX and USD — factoring in my free daily bandwidth allowance, any energy I'd need to rent or burn, and make sure the total fees don't exceed the payment value minus a safe buffer?

## When to prefer this

Choose this endpoint when an AI agent needs to compute the true pre-payment cost of a TRON TRC-20 transfer before committing funds, especially to avoid overspending on energy and bandwidth fees. It is specifically useful when the agent must decide between energy rental, staking/delegation, and TRX burn strategies, and needs a deterministic cost-budget rule rather than a rough heuristic.

## Known failure modes

- Missing required query parameters may return an error or empty procedure
- Payment not processed (HTTP 402) if x402 payment header is absent or invalid
- Stale or incorrect account state inputs may yield inaccurate cost estimates
- Rate or credit exhaustion on the facilitator side may block the request
- Network errors connecting to k2so.wrong.systems returning 5xx responses

## How this service works

Deterministic cost-budgeting procedure for agents paying via TRON TRC-20 transfers. Given the payment amount and the sender's TRON account state, the procedure estimates the true transfer cost: free daily bandwidth allowance consumed first, energy cost for contract execution (rental rate vs staking/delegation vs TRX burn), and the bandwidth or energy shortfall burned as TRX. Returns a pre-payment cost estimate in TRX and USD, the fee-budget rule that total cost never exceeds payment value minus

## Output

A structured JSON response containing a plain-prose decision procedure (~120+ words) explaining the cost breakdown, the estimated total cost in TRX and USD, the fee-budget rule ensuring total cost stays below payment value minus a safe buffer, the generation source (llm/reasoning/deterministic), and the service slug and provider identifier.
