AgentData — crypto market data with a checkable record

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.

    }
  }
}

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.

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.

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.
