## 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 47620-multichain-gas-price-api-9448cc6b
```

Example prompt: What's the current gas price on Polygon right now? I need to know if it's cheap enough to submit my transaction.

## When to prefer this

Choose this endpoint when you need current gas price or fee estimates for a specific blockchain network without signing up for an API key, and you want to pay only per call in USDC via x402. Prefer it over subscription-based gas APIs for low-frequency or agent-driven usage where a flat per-call micropayment model is more cost-effective.

## Known failure modes

- Unsupported or misspelled chain name returns an error or empty data
- Insufficient USDC balance causes x402 payment failure and no data returned
- Network RPC unavailability may result in stale or missing gas data
- Malformed chain parameter may return a 400-level error

## How this service works

Non-custodial x402 payment gateway on Solana (1% on-chain fee) plus a pay-per-call Solana data API for agents: token price, account balances, tx lookup, trending DEX pairs, network health. No signup, no API key — pay USDC per call.

## Output

Returns a JSON object with ok status, a data object containing the fetched gas/fee data and a fetchedAt ISO timestamp, and an endpoint identifier confirming the gas-multichain lookup.
