# Phantom API — ApeChain Gas Estimation

> Phantom API — ApeChain Gas Estimation is a paid API for AI agents from phantom-api-omega.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Estimates gas cost for a transaction on the ApeChain network before submission

## Facts

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 phantom-api-apechain-gas-estimation-06dd6cde -d '<json body>'
```

Example prompt: Estimate the gas needed to call this ApeChain smart contract — sender is 0xAbC...123, recipient contract is 0xDeF...456, calldata is 0xa9059cbb...000, and the transaction value is 0.

## When to prefer this

Choose this endpoint when you specifically need gas estimation on the ApeChain network (APE token ecosystem). Prefer it over generic RPC eth_estimateGas calls when you want a pay-per-call, infrastructure-free approach via x402 micropayments without managing your own RPC credentials or subscriptions. Ideal for agents that need to budget ApeChain transactions on-the-fly.

## Known failure modes

- Invalid or malformed address in 'to' or 'from' fields returns an error
- Calldata that would cause a revert may return a simulation failure or revert reason
- Missing required fields may result in a 400-level error
- ApeChain RPC node unavailability may cause timeout or 5xx error
- Value field with incorrect format (non-hex, non-string) may cause a parse error

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns an estimated gas amount (in gas units) required to execute the described transaction on ApeChain, allowing the caller to budget transaction fees and detect likely reverts before committing on-chain.
