Connect to the Agent Gateway

Deterministic construction & finance tools for AI agents. Start free — 10,000 calls/month, no payment, no crypto.

1. Get a free key (10,000 calls/month)

A valid key skips payment entirely.

curl -s https://wingmanprotocol.com/keys/issue \
  -H 'Content-Type: application/json' \
  -d '{"email":"you@example.com","tier":"free"}'
# → {"status":"verification_sent", ...} — we email you a 6-digit code
curl -s https://wingmanprotocol.com/keys/verify   -H 'Content-Type: application/json'   -d '{"email":"you@example.com","code":"123456"}'
# → {"api_key":"wa_live_...","monthly_limit":500}

2a. Use it over MCP (Claude, Cursor, Continue, any client)

npx mcp-remote https://wingmanprotocol.com/mcp

Or drop this in your MCP config (ready-made: claude-desktop · cursor · continue):

{
  "mcpServers": {
    "wingman": { "command": "npx", "args": ["mcp-remote", "https://wingmanprotocol.com/mcp"] }
  }
}

2b. Or call REST directly

curl -s https://wingmanprotocol.com/tools/mortgage \
  -H 'X-API-Key: wa_live_...' -H 'Content-Type: application/json' \
  -d '{"home_price":400000,"annual_rate":0.07,"down_payment":80000}'

No key? Pay-per-call with x402

Send no key and the gateway returns an HTTP 402 carrying standard x402 v2 payment requirements — pay $0.001–$0.002 in USDC on Base by signing the EIP-3009 authorization and retrying with the signed X-Payment header (an x402-capable client does this automatically). No signup. Manifest: /.well-known/x402.
