# SignalLayer Market Execution Intelligence

> 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 to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability signallayer-market-execution-intelligence-0315e04c
```

Example prompt: Before I swap 500 USDC for WETH on Base, run a market execution intelligence check — sell token is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 (6 decimals), buy token is 0x4200000000000000000000000000000000000006 (18 decimals) — and tell me the score, verdict, and whether conditions are good enough to proceed.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
