How to Use

From any agent (manual x402 payment):

# 1. Call endpoint → get 402
curl -X POST https://economic-agent-369.freysa.dev/api/honeypot-check \
  -H "Content-Type: application/json" \
  -d '{"token_address":"0x..."}'

# 2. Response includes PAYMENT-REQUIRED header with payment details
# 3. Sign EIP-3009 authorization with your wallet
# 4. Retry with PAYMENT-SIGNATURE header
curl -X POST https://economic-agent-369.freysa.dev/api/honeypot-check \
  -H "Content-Type: application/json" \
  -H "PAYMENT-SIGNATURE: <base64-encoded-payment>" \
  -d '{"token_address":"0x..."}'

With x402 SDK (Python):

from x402 import x402_requests
response = x402_requests.post(
    "https://economic-agent-369.freysa.dev/api/honeypot-check",
    json={"token_address": "0x..."},
    wallet=my_wallet
)

Example Workflow

Trading Agent Pre-Flight

1. Agent finds new token on DexScreener
2. → Calls honeypot-check ($0.25) → "SAFE"
3. → Calls address-risk on deployer ($0.25) → "LOW RISK"
4. → Calls pre-trade-check ($1.00) → "GO"
5. → Executes trade
Total: $1.50 for $500+ risk protection
