## About

# 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   → 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

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

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

## Setup (One-Time)

```bash
# 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  --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 ` | 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

```bash
# 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.

**Context storage:** `~/.config/corbits/context.json`
**Base URL:** `https://api.corbits.dev`

## Funding Your Wallet

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

### Buy USDC with Fiat

```bash
# Ethereum (standard)
mp buy --token usdc_ethereum --amount 50 --wallet  --email 

# Polygon (lower gas)
mp buy --token usdc_polygon --amount 50 --wallet  --email 
```

### Swap ETH → USDC

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

### Bank Transfer (Large Budgets)

```bash
mp virtual-account create
mp virtual-account kyc continue
mp virtual-account bank-account register
mp virtual-account onramp create \
  --name "Corbits Onramp" \
  --fiat usd \
  --stablecoin usdc \
  --wallet  \
  --chain ethereum
```

### Deposit Link (Permissionless)

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

```bash
mp deposit create \
  --name "Corbits Agent Fund" \
  --wallet  \
  --chain ethereum --token USDC
```

### Check Balance

```bash
mp token balance list --wallet  --chain ethereum
```

### Auto Top-Up

Keep the wallet funded automatically in agent pipelines:

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

if (( $(echo "$BALANCE  --email `
4. `mp wallet export --wallet "corbits-agent"` — copy EVM private key
5. `/corbits init` — paste key when prompted
6. `/corbits search ` — discover APIs
7. `/corbits call` — payment auto-deducted from MoonPay wallet
8. Top up when needed: `mp buy` or `mp token bridge`
