Measured tools (5)

• signal_layer_router read-only

  Free deterministic task-to-tool router, not a full catalog. Returns match, recommendedTool, routingConfidence, reason, missingRequiredInputs and readyToCall HTTP/MCP arguments for the best eligible primitive, or an explicit no_match when nothing fits. It may recommend a paid tool but never authorizes payment; check the live x402 challenge and obtain user approval before spending.

  Parameters:

  • task (required) — string
  • amount — string
  • fields — array
  • target — string
  • network — string
  • buyToken — string
  • sellToken — string
  • maxPriceUsd — number
  • buyTokenDecimals — integer
  • sellTokenDecimals — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• signal_layer_catalog read-only

  Free inventory returning service, version, defaultEntryPoint and the four actionable primitives with capabilities and prices; the catalog tool itself is omitted. This is not a task router. If the correct tool is uncertain, prefer signal_layer_router.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• agent_preflight read-only

  Inspects public x402 terms or a Base recipient and returns decision.verdict, score, confidence, payment observations, evidence, warnings, freshness and nextActions. It identifies observable mismatches but cannot guarantee safety or authorize spending. 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 per call via x402 V2 with separately authorized payment. If unsure, use the free signal_layer_router.

  Parameters:

  • target (required) — string
  • intent — string
  • routingId — string
  • maxPriceUsd — number
  • expectedNetwork — string

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• market_execution_intel read-only

  Analyzes current Base ERC-20 exact-in swap quotes without executing trades. Returns quote-derived buy amount, network-cost bps, size-impact estimate, decision, evidence, warnings and freshness. Quotes can change; no signing or investment advice. 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 per call via x402 V2 with separately authorized payment. If unsure, use the free signal_layer_router.

  Parameters:

  • sellToken (required) — string
  • buyToken (required) — string
  • amount (required) — string
  • sellTokenDecimals (required) — integer
  • buyTokenDecimals (required) — integer
  • routingId — string

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• structured_extract read-only

  Extracts requested fields from public webpages, returning structured values, field-level evidence, confidence, freshness and partial-result warnings. Missing facts remain null. 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. Use signal_layer_router for free tool selection.

  Parameters:

  • url (required) — string
  • fields (required) — array
  • routingId — string

  Hints: read-only yes · destructive no · idempotent yes · open-world yes
