Conformally-calibrated price forecast: an honest 80% prediction interval (range_80, ~0.80 empirical coverage) plus point return and upside probability for BTC/ETH/SOL/XRP/ADA. Directional bias is supporting context; the calibrated range is the product.

Step 1 of the verified decision loop. Checks market state, cooldown, data freshness, signal context, and warnings before /kronos/decision.

Full site quality audit: 22 checks across SEO (titles, descriptions, canonical, Open Graph, JSON-LD…), accessibility (alt text, form labels, heading order, landmarks…) and security headers (HSTS, CSP, XCTO…) — scored 0-100 per section with a copy-paste fix for every finding. $5 per audit. Fetch-based (served HTML; SPA shells noted). The agent-readiness scan is separate and free at /api/x402/deep-scan.

Every energy benchmark in one call: WTI and Brent crude oil spot, Henry Hub natural gas spot, and US regular retail gasoline — each with its latest price, prior reading, and change. The catalog's commodities feed (no equity/forex/crypto endpoint carries these). For one benchmark with history use /api/v1/energy/{product}. Source: U.S. Energy Information Administration (EIA).

The combined market regime — one read fusing the stock Fear & Greed score and velocity, VIX, insider-buying sentiment, and net liquidity into a named regime (e.g. Mixed Signals) with severity and a suggested stance, plus how the S&P 500 historically performed after similar regimes (forward 5/22-day and 1/3-month returns and win rates). From x402stock, a market & economic data API (x402, USDC).

Use to monitor tokenized US equities (xStocks) against their real underlyings: every tracked xStock's on-chain price decoded from Raydium CLMM pool state on the public Solana ledger (no Backed/Chainlink/Pyth API), the underlying's live quote, and the premium/discount percent — plus pool liquidity, scaled-UI multiplier, and a us_market_open arb-context flag.

Reads a Gnosis Safe's live spending authority straight from the chain -- current owner set, threshold, enabled modules and transaction guard -- and compares it against the same Safe's state at an earlier block, flagging added/removed owners, added/removed modules and threshold changes. Needs no stored baseline and no subscription: the earlier state is read from chain history on the same call, so the very first request already answers 'has this changed'. Why pay instead of reading it yourself: the historical reads only work on archive-capable endpoints (several common public RPCs refuse them outright or serve pruned state), an enabled module can move funds with no owner signatures at all, and the block where the change landed is narrowed by binary search over chain history rather than assumed. Required query parameters: chain_id and address.
