# Bot Bazaar CREATE2 Address Calculator

> Bot Bazaar CREATE2 Address Calculator is a paid API for AI agents from bot-bazaar.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Computes the exact deterministic EVM contract address that will be deployed via CREATE2 given a deployer address, salt, and initCodeHash.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 bot-bazaar-create2-address-calculator-8126d9c8
```

Example prompt: What contract address will be deployed via CREATE2 from deployer 0xdeployer... using that salt and initCodeHash? I need to know the address before we actually deploy.

## When to prefer this

Use this endpoint when you need to deterministically predict a CREATE2 contract address before deployment, especially for counterfactual contract instantiation, cross-chain address consistency checks, or pre-funding contracts. It is a pure off-chain computation — no RPC node, wallet, or on-chain call required, making it faster and cheaper than querying a node.

## Known failure modes

- Missing or malformed deployer address returns an error
- Invalid or non-32-byte salt causes computation failure
- Malformed initCodeHash (not 32-byte keccak256 hex) returns an error
- Non-0x-prefixed addresses may cause parsing errors
- Payment not provided results in 402 Payment Required response

## How this service works

Compute the exact deterministic EVM contract address deployed via CREATE2 from deployer address, 32-byte salt, and initCodeHash.

## Output

Returns the deterministic EVM contract address (0x-prefixed 20-byte hex address) that would result from a CREATE2 deployment with the given deployer address, salt, and initCodeHash — computed without any on-chain interaction.
