Returns the current fee rates for the usual confirmation targets together with the state of the mempool behind them, and then does the part that is usually missing: it estimates the virtual size of the transaction you describe and computes the resulting total fee in satoshis for each target.

Returns the total value locked of a protocol, its distribution across chains, and the change over one day, seven days and thirty days, together with its share of the category. The distinction that justifies the service is between flow and valuation: TVL is denominated in dollars, so when the price of the deposited token falls the TVL falls with it although not one user withdrew anything, and a thirty percent TVL drop in a week when the token lost thirty percent is not an outflow.

Returns European Central Bank reference rates through frankfurter.dev: one base currency against the symbols you name, each with the value date the rate belongs to. Optionally a comparison date is fetched too and the change per currency is computed in percent, so a move is visible without a second call. Cross rates between two non-euro currencies are derived through the base and marked as derived.

Per-symbol HOLD-STATE read — is the published trend state behind a name intact? GET /api/board/hold?sym=NVDA (up to 10, comma-separated, one price) returns each name's state, hold strength 0-100, readiness, maturity-late flag, overnight gap-risk grade and its book's regime, with the mechanical rules states flip on. BTC-USD/ETH-USD return the crypto book's IN|CASH daily-close state. Impersonal publication — never your entry or size. ~5-min refresh in market hours. Research, not advice.

Market regime classifier for trading agents — is the tape risk-on or risk-off right now? Returns a regime verdict per book (S&P 500, Nasdaq-100, macro, crypto): trade, be selective, or stand down — with the market-state mode, which sectors are green, and the top-down permission ladder (index → sector → name) saying whether individual names are enterable at all. Refreshed ~5 min in market hours, timestamped. Research, not advice.

Bitcoin and Ethereum trend signal — is crypto risk-on right now? One read returns the long-only trend state for BTC and ETH (LONG or CASH per sleeve), each sleeve's 50-day trend gate, and the BTC 200-day master gate that overrides both — all evaluated strictly on UTC daily closes, with live price and day change. A rules-based regime verdict for agents, not raw price data. Long-only: the answer is in or out, never short. Research, not advice.

Index scores for trading agents — how strong is each major index right now? One read returns the scored index row per book: S&P 500 (SPY) and Nasdaq-100 (QQQ) plus the macro and BTC/ETH crypto books — 0-100 opportunity score, percentile, green/yellow/red light and entry state for each index, with every book's regime verdict alongside. The cheapest top-down read of the whole tape. Refreshed ~5 min in market hours, timestamped. Research, not advice.

Wallet sanctions check for a validated EVM or Solana address. Returns a direct verdict, recommended action, match evidence, source lists, and an explicit AML-scope caveat.
