Apiosk - Keyless API Access with USDC Micropayments

Pay-per-request API access for agents. No API keys. No accounts. Just pay and call.

Apiosk enables agents to access production APIs using x402 protocol - USDC micropayments on Base blockchain. Stop managing API keys, start paying per request.

🎯 What This Skill Does

Discover APIs - Browse 9+ production APIs (weather, prices, news, geocoding, etc.)
Pay per request - Automatic USDC micropayments ($0.001-0.10 per call)
No setup - No API keys, no accounts, no subscriptions
Instant access - Call APIs immediately with x402 payment

📦 Installation

bash

# Via ClawHub
clawhub install apiosk

# Or clone manually
git clone https://github.com/apiosk/apiosk-skill

⚙️ Configuration

1. Set Up Wallet (One-time)

bash

# Generate new wallet (or import existing)
./setup-wallet.sh

# This creates ~/.apiosk/wallet.json with:
# - Private key (stored locally, chmod 600 for security)
# - Public address
# - Base mainnet RPC

**IMPORTANT:** The private key is stored in plaintext in `~/.apiosk/wallet.json` (with restrictive file permissions). Only fund this wallet with small amounts for testing. For production, use a hardware wallet or external key management.

Important: Fund your wallet with USDC on Base mainnet (minimum $1-10 recommended).

How to fund:

Bridge USDC to Base via https://bridge.base.org
Or buy USDC on Coinbase → withdraw to Base
Send to your Apiosk wallet address

2. Discover Available APIs

bash

# List all APIs
./list-apis.sh

# Output:
# weather       $0.001/req   Get current weather and forecasts
# prices        $0.002/req   Crypto/stock/forex prices  
# news          $0.005/req   Global news by topic/country
# company       $0.01/req    Company info, financials, news
# geocode       $0.001/req   Address → Coordinates
# ...

🚀 Usage

Basic API Call

bash

# Call weather API
./call-api.sh weather --params '{"city": "Amsterdam"}'

# Output:
# {
#   "temperature": 12,
#   "condition": "Cloudy",
#   "forecast": [...]
# }
# 
# ✅ Paid: $0.001 USDC

From Agent Code (Node.js)

javascript

const { callApiosk } = require('./apiosk-client');

// Call weather API
const weather = await callApiosk('weather', {
  city: 'Amsterdam'
});

console.log(`Temperature: ${weather.temperature}°C`);
// ✅ Automatically paid $0.001 USDC

From Agent Code (Python)

python

from apiosk_client import call_apiosk

# Call prices API
prices = call_apiosk('prices', {
    'symbols': ['BTC', 'ETH']
})

print(f"BTC: ${prices['BTC']}")
# ✅ Automatically paid $0.002 USDC

🎓 Examples

Example 1: Weather Bot

javascript

const { callApiosk } = require('./apiosk-client');

async function getWeatherReport(city) {
  const weather = await callApiosk('weather', { city });
  
  return `🌤️ Weather in ${city}:
Temperature: ${weather.temperature}°C
Condition: ${weather.condition}
Forecast: ${weather.forecast.map(f => f.summary).join(', ')}
  
💰 Cost: $0.001 USDC`;
}

// Usage
console.log(await getWeatherReport('Amsterdam'));

Example 2: Crypto Price Tracker

python

from apiosk_client import call_apiosk
import time

def track_prices(symbols, interval=60):
    """Track crypto prices with Apiosk"""
    while True:
        prices = call_apiosk('prices', {'symbols': symbols})
        
        for symbol, price in prices.items():
            print(f"{symbol}: ${price:,.2f}")
        
        print(f"✅ Paid: $0.002 USDC\n")
        time.sleep(interval)

# Track BTC and ETH every minute
track_prices(['BTC', 'ETH'])

Example 3: News Digest Agent

javascript

const { callApiosk } = require('./apiosk-client');

async function getDailyDigest(topics) {
  const articles = [];
  
  for (const topic of topics) {
    const news = await callApiosk('news', { 
      topic, 
      limit: 3 
    });
    articles.push(...news.articles);
  }
  
  return `📰 Daily Digest (${articles.length} articles)
${articles.map(a => `- ${a.title} (${a.source})`).join('\n')}

💰 Total cost: $${(topics.length * 0.005).toFixed(3)} USDC`;
}

// Get tech + business news
console.log(await getDailyDigest(['technology', 'business']));

🔐 How x402 Works

Traditional API:

text

1. Sign up for account
2. Get API key
3. Store securely
4. Include in requests
5. Monitor rate limits
6. Pay monthly subscription

Apiosk (x402):

text

1. Make request
2. Gateway returns 402 Payment Required
3. Your wallet signs payment proof
4. Gateway verifies on-chain
5. Gateway forwards to API
6. You get response

Time: Milliseconds. Cost: Exact usage. Setup: Zero.

🛠️ Advanced Configuration

}

Set Spending Limits

bash

# Set daily spending limit
./set-limit.sh --daily 10.00

# Set per-request max
./set-limit.sh --per-request 0.10

Enable Notifications

bash

# Get notified when balance is low
./configure.sh --alert-balance 1.00 --alert-webhook "https://hooks.slack.com/..."

📊 Monitoring & Analytics
