Measured tools (35)

• get_overnight_risk_brief

  Decision-ready overnight risk brief ($0.012 USDC): DEX-vs-CEX spreads, liquidation zones, funding predictions, sentiment, stablecoin health, and recorded changes since this wallet last called it. 20% cheaper than buying the five parts separately, and one settlement instead of five.

  Parameters:

  • payment — string — Optional. Base64 x402 payment payload you signed yourself (ERC-3009 TransferWithAuthorization, USDC on Base). Call without it once to receive the payment requirements, sign those, then call again with this argument. This server forwards the payload and never holds a key.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_changes_since_last_call

  Only what changed for a signal since THIS wallet last paid for it ($0.001 USDC — cheaper than any full payload). Replaces repeated polling: the server keeps the cursor, keyed to your wallet, so you never re-download or re-diff data you already have. Requires signal=. First call returns the last 24h.

  Parameters:

  • signal (required) — string — sentiment, funding-rates, liquidation-levels, volatility, correlation, positioning, supply, stablecoin-health, macro-onchain, defi-yields, dex-vs-cex, arbitrage-opportunities, funding-predictions
  • payment — string — Optional. Base64 x402 payment payload you signed yourself (ERC-3009 TransferWithAuthorization, USDC on Base). Call without it once to receive the payment requirements, sign those, then call again with this argument. This server forwards the payload and never holds a key.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• watch_condition

  Register a standing condition and let the always-on server watch it for you ($0.010 USDC, up to 168h). An agent only exists while it runs and cannot wait; this is that missing faculty. Poll watch_status free instead of paying for repeated data calls.

  Parameters:

  • signal (required) — string
  • op (required) — string
  • threshold (required) — number
  • hours — number — lifetime, 1-168, default 24
  • payment — string — Optional. Base64 x402 payment payload you signed yourself (ERC-3009 TransferWithAuthorization, USDC on Base). Call without it once to receive the payment requirements, sign those, then call again with this argument. This server forwards the payload and never holds a key.
  • subject — string — e.g. BTC_USDT

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_memecoin_risk

  Memecoin risk verdict for one token on Solana or Base ($0.005 USDC): LOW, ELEVATED, HIGH or CRITICAL with every finding behind it — liquidity against real assets only, mint and freeze authority, honeypot and sell tax, liquidity lock, holder concentration. What a source cannot supply is reported as unknown, never as a pass. Each verdict is filed as a claim and scored publicly at /calibration after 7 days.

  Parameters:

  • chain (required) — string — Chain the token lives on
  • token (required) — string — Mint address (Solana) or 0x contract address (Base)

• get_new_memecoins

  New memecoin pools on Solana or Base, screened every 15 minutes ($0.010 USDC): each with its risk verdict, the market at screening time and whether its 7-day claim has resolved. The same population the public track record is computed from.

  Parameters:

  • chain — string
  • hours — integer — look-back window, 1-72
  • payment — string — Optional. Base64 x402 payment payload you signed yourself (ERC-3009 TransferWithAuthorization, USDC on Base). Call without it once to receive the payment requirements, sign those, then call again with this argument. This server forwards the payload and never holds a key.
