# Phantom API — Abstract Network Gas Estimator

> Phantom API — Abstract Network Gas Estimator 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 2026-09-14).

Estimates gas costs for a transaction on the Abstract blockchain network given sender, recipient, calldata, and value.

## 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-abstract-network-gas-estimator-7323580b -d '<json body>'
```

Example prompt: Before I send this transaction on Abstract, estimate the gas cost — it's from 0xAbcD...1234, going to contract 0x5678...EfGh, with calldata 0xa9059cbb...0000 and a value of 0.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call gas estimate specifically for the Abstract EVM-compatible network without managing your own RPC infrastructure. Prefer it over generic Ethereum gas estimators when the target chain is Abstract, and when you want simple REST access without setting up a full Web3 provider.

## Known failure modes

- Invalid or malformed Ethereum address in 'to' or 'from' fields returns an error
- Malformed or non-hex 'data' calldata field causes a parsing error
- Network unavailability or RPC node failure may result in a timeout or 503 error
- Transactions that would revert on-chain may return an execution-reverted error rather than a gas estimate
- Missing required fields may cause a 400 Bad Request
- Payment failure (insufficient USDC) results in 402 Payment Required

## 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) needed to execute the specified transaction on the Abstract network, allowing the caller to anticipate fees before broadcasting.
