# LoboMint Gas Price & USDC Transfer Cost Oracle

> LoboMint Gas Price & USDC Transfer Cost Oracle is a paid API for AI agents from shop.netlobo.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Returns the live Base mainnet gas price in wei/gwei plus the USDC-denominated cost of standard ERC-20 and ETH transfers, so x402 agents can budget total transaction costs in USDC.

## 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 lobomint-gas-price-usdc-transfer-cost-oracle-f4e2c32a
```

Example prompt: What's the current gas price on Base mainnet right now, and how much would a standard USDC transfer cost me in gas, expressed in USDC?

## When to prefer this

Choose this endpoint when an AI agent or x402 buyer needs to budget the full cost of a Base transaction in USDC terms — combining gas price and ETH/USD conversion in a single call. Ideal for pre-flight cost checks before executing x402 micropayments, or any workflow that needs real-time Base gas fees expressed in USDC rather than ETH/gwei.

## Known failure modes

- Upstream ETH/USD price feed unavailable — may return stale or null spot price
- Base RPC node unreachable — call fails or times out
- Payment of $0.01 USDC via x402 fails — 402 response with payment details required
- Network congestion causing slow RPC response

## How this service works

Per-call data and LLM products, paid in USDC on Base via x402. No accounts, no API keys: each request returns 402 with a payment challenge.

## Output

A JSON object containing the chain name ('base'), chain ID ('eip155:8453'), current gas price in wei and gwei, the ETH/USD spot rate, and the USDC-denominated cost of both a 21,000-gas (ETH transfer) and 65,000-gas (ERC-20 transfer) transaction. All values are fetched live per call.
