Integration

One call. No keys.

Machine-native payments via x402. Your agent signs a USDC authorization — Sigmatic settles on Base. No monthly invoice.

Python · x402 auto-pay 
# pip install x402[fastapi] httpx
from x402.http.clients.httpx import x402HTTPClient
from x402.mechanisms.evm.signers import LocalSigner

http = x402HTTPClient(signer=LocalSigner("0x..."))

# Fleet scorecard — free
fleet = await http.get(
  "https://api.sigmatic.lol/v1/clusters/Zyfai%20Rebalancer%20Agent/performance"
)

# Trust check — $0.001 auto-settled
trust = await http.get(
  "https://api.sigmatic.lol/v1/agents/22724/trust"
)
# → {"trust_tier":"high","score":0.84}
