Tools

Paid (USDC via x402)

Free

Payment

ShippingRates uses the x402 protocol — the internet's native payment standard for AI agents.

• Currency: USDC (stablecoin, always $1.00)
• Networks: Base Mainnet (EVM) + Solana Mainnet
• Facilitator: PayAI — free, no API key needed
• Settlement: Instant (~200ms)
• No API keys, no accounts, no subscriptions

Your agent sends a request → gets HTTP 402 with payment terms → signs USDC payment → retries with proof → gets data. All handled automatically by x402 client libraries.

Supported x402 Client Libraries

• TypeScript: @x402/fetch or @x402/axios
• Python: x402 package (httpx / requests)
• Go: x402 Go module

Payment Wallets

Data Coverage

API Access

For direct API integration (without MCP):

Example: D&D Calculate

# Free endpoint — no payment needed
curl https://api.shippingrates.org/api/stats

# Paid endpoint — returns HTTP 402 with payment instructions
curl -X POST https://api.shippingrates.org/api/dd/calculate \
  -H "Content-Type: application/json" \
  -d '{"line": "maersk", "country": "IN", "container_type": "40HC", "days": 14}'

Example Response (D&D Calculate)

{
  "line": "maersk",
  "country": "IN",
  "container_type": "40HC",
  "days": 14,
  "free_days": 4,
  "currency": "USD",
  "slabs": [
    { "from": 5, "to": 7, "rate_per_day": 7.5, "days": 3, "cost": 22.5 },
    { "from": 8, "to": 14, "rate_per_day": 15, "days": 7, "cost": 105 }
  ],
  "total_cost": 127.5
}
