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-injective-gas-estimator-6a3b6dc8 -d '<json body>'
```

Example prompt: Estimate the gas needed for an Injective transaction from address inj1abc...sender to inj1xyz...recipient with data payload 0xabcdef and a value of 1000000000000000000.

## When to prefer this

Use this endpoint when you need to estimate gas costs specifically on the Injective blockchain network before submitting a transaction. Prefer this over generic gas estimators when working with Injective's native ecosystem, INJ token transfers, or Injective-compatible smart contracts. Suitable for pre-flight checks, fee budgeting, and user-facing fee previews in Injective-based dApps.

## Known failure modes

- Invalid or malformed address in 'to' or 'from' fields returns a 400 error
- Unparseable data payload causes estimation failure
- Network unavailability or Injective RPC node downtime returns 5xx error
- Missing required fields may return a validation error
- Insufficient or incorrect value format may cause estimation to fail

## 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 specified transaction on the Injective blockchain, helping callers budget fees before broadcasting the transaction.
