# MolCloud Crypto Gas Price Lookup

> MolCloud Crypto Gas Price Lookup is a paid API for AI agents from api.molcloud.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-17).

Returns current gas prices and estimated transaction costs in USD for a specified blockchain network (defaulting to Base).

## 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 molcloud-crypto-gas-price-lookup-78503444
```

Example prompt: What are the current gas fees on Base — give me the base fee in Gwei and an estimate of what a USDC transfer would cost in USD right now?

## When to prefer this

Use this endpoint when an AI agent needs real-time gas fee data specifically for the Base network (or other supported EVM chains) before deciding whether to execute an on-chain transaction. Prefer it over generic blockchain explorers when operating in an agentic x402 pay-per-use context where sub-cent micropayments are acceptable and speed matters.

## Known failure modes

- Unsupported network name returns an error or empty data
- Network RPC unavailability may cause stale or missing gas data
- Missing or malformed 'network' query param falls back to Base default
- x402 payment failure (insufficient USDC balance) blocks the request

## How this service works

41 pay-per-request AI, search, headless browser, crypto alpha & memory APIs for autonomous agents settling in USDC on Base via x402 v2.

## Output

Returns a JSON object with the current base fee in Gwei for the requested network and estimated transaction costs in USD (e.g. USDC transfer cost), plus the endpoint path and a success status.
