x402
SignalLayer Market Execution Intelligence is a paid API for AI agents from signallayer.floot.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-19).
Returns a scored execution-readiness verdict (pass/fail, confidence, network cost, size impact) for a proposed on-chain token swap on Base, priced per call via x402 USDC micropayment.

How this service works
Machine-native decision and data primitives for autonomous agents, paid per call with x402 V2 USDC on Base.
Output
A JSON object containing: a decision block with a numeric score (0-100), a pass/fail verdict, and a confidence value (0-1); a data block with the Base network cost in basis points and an estimated size impact in basis points; a freshness block indicating when the data was checked and its maximum valid age in seconds; plus the tool name and status.
Example use cases
Pre-trade swap quality check
“Before my agent executes the USDC-to-cbBTC swap on Base, can you get me the market execution intelligence verdict — selling 2000 USDC (address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, 6 decimals) for cbBTC (address 0xcbB7C0000aB88B473b1f5aFd9ef808440eed33Bf, 8 decimals) — and pass only if the score is above 80?”
Autonomous DeFi agent trade gating
“My trading bot is about to sell 10000 USDC for WETH on Base. Check the execution intel first — sellToken 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 with 6 decimals, buyToken 0x4200000000000000000000000000000000000006 with 18 decimals — and only let the trade through if the verdict is pass and confidence is above 0.75.”
Network cost and impact monitoring
“I want to know the current network cost in basis points and size impact estimate for swapping 500 USDT (address 0xdAC17F958D2ee523a2206206994597C13D831ec7, 6 decimals) to DAI (address 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb, 18 decimals) on Base — give me the full SignalLayer execution intel breakdown.”
Technical details
Endpoint
GEThttps://signallayer.floot.app/_api/v1/market/execution-intel?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent needs a machine-native, scored go/no-go signal on a specific token swap before executing on Base — especially when network cost and size impact primitives are needed in a single low-latency call. Prefer this over raw DEX quotes when you need a composite execution quality verdict with confidence scoring rather than just a price. Ideal for agent-driven DeFi workflows that gate trade execution on a quantitative readiness score.
Side effects
- Missing required query params (sellToken, buyToken, amount) returns a 400 or schema validation error
- Invalid ERC-20 contract address returns an error or zero-confidence verdict
- Payment not attached or insufficient USDC via x402 returns a 402 Payment Required response
- Stale market data may be returned if freshness maxAgeSeconds threshold is exceeded
- Unsupported token pairs on Base may return low-confidence or incomplete results
