Tools
| Tool | Description | Behaviour |
|---|---|---|
| agent_preflight | Before paying, transferring to, or interacting with an unfamiliar machine resource, x402 endpoint, recipient, or Base address. Do NOT use when: You only need market execution conditions or webpage extraction. Price: $0.01 USDC via x402. If uncertain which SignalLayer primitive matches the task, call signal_layer_router first for free. | Not declared |
| market_execution_intel | Before an exact-in ERC-20 swap on Base when current quote-derived execution conditions, network cost, and size sensitivity matter. Do NOT use when: You need generic historical prices, personalized investment advice, or a signed transaction. Price: $0.03 USDC via x402. If uncertain which SignalLayer primitive matches the task, call signal_layer_router first for free. | Not declared |
| signal_layer_catalog | Free machine-readable SignalLayer capability catalog. Use this to enumerate all SignalLayer tools and prices. If the correct tool is uncertain, prefer signal_layer_router. | Not declared |
| signal_layer_router | Free deterministic SignalLayer task router. USE THIS when the task is known but the correct SignalLayer primitive is not. Returns either no_match or one recommended tool with price, missing inputs, and ready-to-call HTTP and MCP arguments. It never forces a paid recommendation. | Not declared |
| structured_extract | When requested facts exist on a public webpage but compact structured JSON is needed instead of browsing and parsing the page. Do NOT use when: The source is already structured or the task is generic web search. Price: $0.02 USDC via x402. If uncertain which SignalLayer primitive matches the task, call signal_layer_router first for free. | Not declared |
