sigint-os

Client SDK for SIGINT — the autonomous ETH signal agent.

SIGINT reads live on-chain data (funding rates, liquidations, DEX/CEX volume), forms a directional conviction on ETH, executes a real USDC trade with its own money, then returns the signal with a tradeHash — verifiable proof it had skin in the game before you paid.

Every call costs $0.05–$0.20 USDC via x402, paid automatically.

Install

npm install sigint-os pinion-os
# or
bun add sigint-os pinion-os

Requires a wallet with USDC on Base for the x402 payment.

Usage

One-liner

import { getEthSignal } from "sigint-os"

const signal = await getEthSignal({
  privateKey: process.env.WALLET_KEY  // wallet with USDC on Base
})

console.log(signal.direction)    // "up" | "down"
console.log(signal.confidence)   // 72
console.log(signal.reasoning)    // "Funding rate positive at 0.02%, longs crowded..."
console.log(signal.tradeHash)    // "0xb910..." — agent's own trade on Base

Reusable client

import { SigintClient } from "sigint-os"

const sigint = new SigintClient({ privateKey: process.env.WALLET_KEY })

// Call as many times as you need
const signal = await sigint.getSignal()

With PinionOS directly (no SDK)

import { PinionClient, payX402Service } from "pinion-os"

const pinion = new PinionClient({ privateKey: process.env.WALLET_KEY })
const signal = await payX402Service(
  pinion.signer,
  "https://sigint-agent-production.up.railway.app/signal/eth"
)

Signal Response

{
  direction: "up" | "down",          // ETH price direction prediction
  confidence: number,                 // 0–100
  currentPrice: number,               // ETH price at signal formation
  resolveAt: number,                  // UNIX ms — when prediction resolves (1h)
  reasoning: string,                  // agent's on-chain analysis
  tradeHash: string | null,           // agent's own trade hash (verify on Basescan)
  onchainContext: {
    fundingRate: number,              // 8h funding rate (%)
    liquidationBias: string,          // "long-heavy" | "short-heavy" | "balanced"
    dexCexVolumeRatio: number         // DEX vol / CEX vol
  },
  trackRecord: {
    correct: number,                  // count of correct resolved signals
    total: number,                    // count of all resolved signals
    tradePnl: number                  // agent's cumulative trade PnL in USDC
  }
}

The tradeHash is verifiable on Basescan — the agent executed a real USDC → ETH swap before generating this response.

How It Works

1. You call getEthSignal() — your wallet pays $0.05–$0.20 USDC via x402
2. SIGINT fetches live on-chain context (price, funding, liquidations, volume)
3. SIGINT reasons with skills.chat() → forms direction + confidence
4. SIGINT executes its own $0.50 USDC → ETH trade on 1inch (before responding)
5. Signal returned with tradeHash — the agent committed first
