Corbits — Paid API Marketplace for AI Agents

Overview

Corbits is a discovery and proxy platform for premium APIs. Agents search, select, and call paid APIs with automatic per-request USDC micropayments via the x402 protocol. MoonPay provides the wallet that powers every payment — your MoonPay wallet IS your Corbits payment wallet.

/corbits search <topic>  → find matching API proxies
/corbits list            → browse endpoints + USDC pricing
/corbits call            → select endpoint → review cost → confirm → execute
                           (payment auto-deducted from MoonPay wallet)

Supports: EVM wallets (Ethereum, Polygon, Base, Arbitrum) and Solana

Prerequisites

# 1. Install Corbits skill
npx clawhub@latest install corbits

# 2. Install MoonPay CLI
npm install -g @moonpay/cli
mp login

Setup (One-Time)

# 1. Create your payment wallet
mp wallet create --name "corbits-agent"
mp wallet retrieve --wallet "corbits-agent"  # note your EVM address

# 2. Fund with USDC
mp buy --token usdc_ethereum --amount 50 --wallet <evm-address> --email <email>

# 3. Export private key for Corbits
# ⚠️ Security: your private key gives full access to your wallet.
# Never share it, commit it, or paste it anywhere other than the corbits init prompt.
# Use a dedicated low-balance wallet — not your primary wallet.
mp wallet export --wallet "corbits-agent"
# Copy the EVM private key

# 4. Initialize Corbits — paste the exported key when prompted
/corbits init

/corbits init stores the key in macOS Keychain or ~/.config/corbits/, scaffolds a TypeScript project with @faremeter/rides, and optionally configures a Solana keypair.

Key Commands

Command	Description
/corbits init	First-time setup (wallet + project scaffold)
/corbits search <query>	Find API proxies by name or category
/corbits list	View all available proxies and endpoint pricing in USDC
/corbits call	Execute a paid API call with auto-payment
/corbits status	Show currently selected proxy

Usage Examples

# Crypto price data
/corbits search "crypto prices"
/corbits list
/corbits call
# → Select: GET /prices/latest
# → Cost: 0.001 USDC
# → Confirm: y
# → Response: { "BTC": 67420.00, "ETH": 3540.00, ... }

# Weather data
/corbits search "weather"
/corbits list
/corbits call

All pricing shown in USDC before execution. The @faremeter/rides library handles x402 payment authentication automatically — no manual transaction signing.

Funding Your Wallet

Corbits payments settle in USDC. Keep a balance before calling paid APIs.

Buy USDC with Fiat

# Ethereum (standard)
mp buy --token usdc_ethereum --amount 50 --wallet <evm-address> --email <email>

# Polygon (lower gas)
mp buy --token usdc_polygon --amount 50 --wallet <evm-address> --email <email>

Swap ETH → USDC

mp token swap \
  --from-wallet corbits-agent --chain ethereum \
  --from-token 0x0000000000000000000000000000000000000000 \
  --to-token 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 \
  --from-amount 0.02

Bank Transfer (Large Budgets)

mp virtual-account create
mp virtual-account kyc submit
mp virtual-account bank-account add
mp virtual-account onramp create \
  --amount 500 --currency usd --chain ethereum --wallet <evm-address>

Deposit Link (Permissionless)

Anyone can fund your Corbits wallet from any chain — auto-converts to USDC:

mp deposit create \
  --name "Corbits Agent Fund" \
  --wallet <evm-address> \
  --chain ethereum --token USDC

Check Balance

mp token balance list --wallet <evm-address> --chain ethereum

Auto Top-Up

Keep the wallet funded automatically in agent pipelines:

BALANCE=$(mp token balance list --wallet <address> --chain ethereum --json | \
  jq '.[] | select(.symbol=="USDC") | .balance')

if (( $(echo "$BALANCE < 5" | bc -l) )); then
  mp token bridge \
    --from-wallet primary --from-chain polygon \
    --from-token 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 \
    --from-amount 20 \
    --to-chain ethereum \
    --to-token 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48
