# Saylor Innovations Gas Estimate (BSC)

> Saylor Innovations Gas Estimate (BSC) is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-30).

Estimates the gas cost for a transaction on BNB Smart Chain (BSC), returning gas units, gas price in gwei, and estimated fee in native BNB.

## 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 saylor-innovations-gas-estimate-bsc-4b6fc525
```

Example prompt: Before I send a transaction to the contract at 0xBf5140A22578168FD562DCcF235E5D43A02ce9B1 on BSC with calldata 0xa9059cbb000000000000000000000000abc...0000000000000000000000000000000000000000000000000de0b6b3a7640000, can you estimate how much gas it will use and what the fee will be in BNB?

## When to prefer this

Use this endpoint when you need to estimate transaction costs specifically on BNB Smart Chain (BSC) before submitting a transaction. It is the right choice when you need gas units, current gas price in gwei, and fee in native BNB in a single call, and when you want to pre-check whether a transaction would revert. Prefer this over Ethereum or Arbitrum gas estimate endpoints when the target contract is deployed on BSC.

## Known failure modes

- Invalid or missing 'to' address returns an error in the error field with null gas values
- Malformed calldata causes revert simulation with reverted=true
- Target contract does not exist on BSC returns null gas estimate
- Network congestion or RPC node unavailability may cause timeout or error response
- If the transaction would revert on-chain, reverted=true is returned with an error description

## How this service works

Gas Estimate (bsc). BNB Chain (BSC) gas estimate for a transaction (to, data, value, from) with the current gas price and total fee in BNB, and a clear revert reason if the call would fail. Use it to price or pre-check a transaction before sending.

## Output

Returns a JSON object with the chain name ('bsc'), estimated gas units, gas price in gwei, estimated fee in native BNB as a string, a boolean indicating if the transaction would revert, and an error message if applicable. Null values are returned for gas fields if the estimation fails.
