Pulse402 — Dual-Chain (Base + Solana) x402 Data Oracle

Pulse402 is an autonomous, high-frequency data oracle designed specifically for autonomous AI agents and trading bots. It streams verified, read-only market intelligence and pre-trade security checks over HTTP and MCP, settling micropayments natively over the x402 V2 protocol on both Base L2 (eip155:8453) and Solana Mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp).

The canonical service is hosted at https://pulse402-oracle.onrender.com and proxied globally with zero latency via Cloudflare Workers at https://pulse402-oracle.ak10082247.workers.dev.

Every response preserves its original observation timestamp and a strict 10-second acquisition TTL. Outages and stale quotes are reported transparently before payment settlement.

Feed	Route	Tier	Price (USDC)	Atomic Units	Description
Base DEX Liquidity	/v1/pulse/base-liquidity	Tier 1	$0.020	20,000	Pinned-block Uniswap V3 & Aerodrome pool reserves, slippage quotes for $100 / $1k / $10k USDC, and pool balance shifts.
GoPlus Threat Intel	/v1/pulse/threat-intel	Tier 1	$0.020	20,000	Real-time honeypot flags, malicious spender checks, and deterministic prompt-injection text sanitization.
Polymarket Velocity	/v1/pulse/polymarket-velocity	Tier 2	$0.050	50,000	Live CLOB orderbook bid/ask depth, 5-minute probability movement, and momentum signals from real exchange price history.
Cross-DEX Arb Routes	/v1/pulse/arb-routes	Tier 2	$0.050	50,000	Distinct-pool gross round-trip quotes across Base pools with fee deductions and pinned-block execution state.
Solana Pump.fun & Raydium	/v1/pulse/solana-velocity	Tier 2	$0.050	50,000	Real-time Solana Pump.fun and Raydium token velocity, trending boosted tokens, 5m volume, and bonding curve status for sniper bots.

2. Dual-Chain Settlement Infrastructure

Pulse402 accepts gasless, partial-signed x402 V2 authorizations on both major agent ecosystems:

A. Base Mainnet (eip155:8453)

• Asset: Circle USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 6 decimals)
• Standard: EIP-3009 TransferWithAuthorization (requires zero gas / 0 ETH from the buyer)
• Merchant Recipient: 0x80E0Ae84679b7f11bE171DaADd492FBECf628cd6
• Settlement: Verified through Coinbase CDP Facilitator & PayAI Facilitator (https://facilitator.payai.network)

B. Solana Mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp)

• Asset: Native SPL USDC (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, 6 decimals)
• Standard: SPL Token TransferChecked inside a sponsored v0 VersionedTransaction (requires zero gas / 0 SOL from the buyer)
• Merchant Recipient: 9wuMysgXwNhtQeqJgGByAiMYc4EjzZ5wUSmnjrrt3ffh
• Merchant USDC ATA: DD3A7jaXFeHcif9eYj6Vhomuxypat5Yxi8ow6wxz27yL
• Sponsored Fee Payer: CjNFTjvBhbJJd2B5ePPMHRLx1ELZpa8dwQgGL727eKww (relayed via PayAI Facilitator)

3. High-Frequency Prepay Session Pass (POST /v1/pass/prepay)

High-frequency algorithmic bots and multi-agent swarms can eliminate on-chain signing latency and save 60%–80% on fees by activating a prepaid session pass:

1. Purchase: Send a one-time $10.00 USDC payment on Base or Solana to POST /v1/pass/prepay.
2. Receipt: Server returns a cryptographically secure session_token with 1,000 prepaid calls valid for 7 days.
3. Execution: Include the header X-Pulse-Session: <token> and Idempotency-Key: <uuid> on any paid endpoint.
4. Zero Latency: Calls execute instantly without waiting for on-chain signature verification or facilitator relay.

4. Model Context Protocol (MCP) & IDE Integration

Pulse402 runs a production Model Context Protocol (MCP) JSON-RPC 2.0 server at: https://pulse402-oracle.ak10082247.workers.dev/mcp

Connecting in Cursor, Windsurf, Zed, or Claude Desktop

Add this snippet to your IDE's MCP configuration:

{
  "mcpServers": {
    "pulse402-oracle": {
      "url": "https://pulse402-oracle.ak10082247.workers.dev/mcp",
      "headers": {
        "MCP-Protocol-Version": "2026-07-28"
      }
    }
  }
}

Available MCP Tools

• pulse_solana_velocity: Real-time Solana Pump.fun and Raydium token velocity, trending boosted tokens, and liquidity depth.
• pulse_base_liquidity: Mandatory pre-swap liquidity and slippage verification on Base DEXs (Aerodrome & Uniswap V3).
• pulse_threat_intel: Honeypot detection, blacklist checks, and prompt-injection text sanitization.
• pulse_polymarket_velocity: Active prediction market probability movement and CLOB orderbook depth.
• pulse_arb_routes: Pinned-block cyclical arbitrage route quotes and profit simulation.
