Coil Scanner — decide what to trade now instead of rebuilding it. Scored stock rankings for agents: which of ~565 S&P 500, Nasdaq-100 and macro names are set up to buy, with per-name opportunity, entry-timing and hold-strength scores; risk-on / be-selective / stand-down regime verdicts; ranked buy-list lanes; plus a long-only BTC/ETH trend book. Not raw OHLCV (that's free) — the judgment, read top-down. Refreshed ~5 min in market hours, timestamped. Research, not advice.

Signed wallet trust fact profile (ECDSA plus a post-quantum ML-DSA-65 companion): presence checks across stablecoins, governance, NFTs, staking, institutional stablecoins, tokenized treasuries, stablecoin deposits, wrapped bitcoin and names, 145 base checks on 27 chains, up to 166 checks on 29 chains with the optional wallets. No score, no opinion: signed evidence organized by dimension. Pay in USDC on Base, Polygon, Arbitrum, Arc, or Solana.

Fetches the recent notes of one public key across several relays and measures six independent signals: posting rate per day, the coefficient of variation of the intervals between posts, how many of those intervals sit within a few seconds of each other, the entropy of the hour-of-day distribution, the share of posts whose text repeats an earlier post verbatim, and the largest burst inside sixty seconds.

Reads a Chainlink aggregator directly from the chain, pulls Pyth and RedStone, queries public exchange tickers and derives spot plus a 30-minute TWAP from the deepest Uniswap V3 pool of the asset against USDC on the requested chain. Every source carries its own age in seconds, its own price and a link to verify it. Nothing is smoothed into an average: the median is stated alongside the full list and the maximum deviation in basis points, because disagreement between sources is the finding, not a

Groups the access records you pass into clients and sorts each in two stages: person or machine, then, for a machine, the purpose. Signals: cadence and its scatter, path shape and consecutive numeric runs, asset share, referer, method mix, not-found share, robots.txt, user agent product token. Each signal returns what was observed, its weight and why. A lead under two points stays unknown. Nothing is stored, no raw IP is returned: IPv4 cut to /24, IPv6 to /48.

Reads the dated futures of Deribit for BTC or ETH and compares each expiry with a spot price whose source is always named in the answer, because a basis computed against a different venue than the future is a different number. By default the Deribit index is used, which sits on the same venue as the contract; choosing a spot venue instead is possible and is then flagged, including the case where that venue quotes in USDT while the contract settles in USD. Annualization only happens above one day

OFAC / FATF / JFSA sanctions screening for any blockchain address. Returns hit list with sanction list source, designation date, and program code.

Reads all incoming ERC-20 transfers of one token to one address within a block or time window and matches them against the receipts you supply. Matching runs first over the transaction hash, which is the strongest link, and otherwise over amount plus payer plus a stated time tolerance; the method used is named for every single match, so a weak match is never mistaken for a strong one. The answer lists matched pairs, receipts without a payment, payments without a receipt, amount mismatches with e

Queries Binance, Coinbase, Kraken, OKX and Bybit in parallel for one BASE/QUOTE pair, four seconds per exchange. An exchange that does not answer drops out with a stated reason and the call stays valid; venues_failed lists them. oldest_age_ms is mandatory and states the age of the oldest quote that entered the comparison, because differences taken from unequal points in time are the most common error in this kind of table. With an optional size the visible book of each exchange is walked as well

Walks the events you pass through the ordered steps you name and reports per step: how many arrived, conversion from the previous step and from the first, drop-off in users and as a rate, and time to the next step as median, p90 and mean. A step counts only if it happened after the one before and inside the window. Where events carry a segment, each is tested against the largest with the same two-proportion test the A/B endpoint uses. Nothing is stored.

Returns the visible order book of Binance, Coinbase, Kraken, OKX or Bybit for one BASE/QUOTE pair. Levels come as [price, size] with bids descending and asks ascending. depth[] states how much turnover sits within 0.5, 1 and 2 percent of the mid per side, in the quote currency, and additionally as depth_usd where the quote is a US dollar unit. group_bps folds levels into price bands whose price is the size weighted average of the band, for agents that do not want a thousand rows. The exchange up

Prüft MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, TLS am Mailserver und DNSSEC einer Domain und leitet daraus Spoofing-Risiko, Punktzahl und Befunde ab. Jeder Befund trägt einen fertigen DNS-Datensatz zum Einfügen statt einer Empfehlung in Prosa. Rein lesend: kein Versand, keine Testmail, keine Relay-Nutzung.

Returns the raw public trade tape of Binance, Coinbase, Kraken, OKX or Bybit for one BASE/QUOTE pair, oldest first, exactly as the exchange reports it — no smoothing, no merging of prints. side is the side of the aggressor: reported directly by Kraken, OKX and Bybit, derived from the maker flag at Binance, and inverted from the maker side at Coinbase; side_source names which case applies. Where an exchange does not publish it, side is "unbekannt" and side_inferred stays false rather than guessin

Reads the receipt of a transaction on Ethereum, Base, Base Sepolia, OP Mainnet, Arbitrum One, Polygon PoS or Avalanche C-Chain and compares it with what you expected to be paid. The comparison runs against the ERC-20 transfer events in the receipt, not against the transaction recipient, because in a token payment the transaction recipient is the token contract and never the seller. Returns every transfer event with sender, recipient, token, raw amount and human amount computed with that token de

Takes what the caller holds and what the seller accepts and works out which combinations can settle the amount. All costs are brought into USD, otherwise no comparison is possible: gas on the source chain plus, where needed, the cost of a swap or a bridge. Routes that require a swap or a bridge are marked explicitly - they often look cheaper on paper and are slower and riskier in practice. Every assumption is named in assumptions; nothing is folded in silently. Limits: gas costs are ORDERS OF MA

For a given chain, token pair and input amount, every connected DEX is queried through its own contracts: Uniswap V3 through the Quoter via eth_call across all fee tiers, constant-product pools through the pool maths on live reserves, Solidly-style pools through their own getAmountOut. Two-hop routes through the wrapped native token and the chain USDC are included, priced by chaining the hops exactly as a real swap would traverse them. Nothing is executed, submitted or handed to a router — every

Resolves a pool either by address or by chain, token pair and DEX, then reads token0, token1, fee tier, reserves, in-range liquidity and the current tick straight from the contract. Exit impact is not estimated from a formula but simulated: for Uniswap V3 through the official Quoter contract via eth_call, which walks the same ticks a real swap would and reports how many it crossed; for constant-product and Solidly pools through the pool maths or the pool own getAmountOut. Nothing is ever execute

Near-real-time pump prices (EUR/L) for French gas stations from the official roulez-eco feed (data.economie.gouv.fr, updated continuously). Query: ?dept=75 (departement code) and/or ?city=Lyon, optional &fuel=gazole|sp95|sp98|e10|e85|gplc to sort cheapest-first and drop stations without that fuel, &limit=10 (1-40). Returns per station: address, lat/lon, per-fuel price with update timestamp, 24/7 automat flag. Cached 10 min.

European Central Bank reference exchange rates for any past date or date range (business days since 1999-01-04), via frankfurter.dev. Query: ?date=2026-05-01 for one day, or ?start=2026-05-01&end=2026-05-08 for a daily series (max 366 days), plus ?base=EUR&symbols=USD,GBP (symbols optional -> all). Series responses nest rates by date. Historical data is immutable; served with a 24h cache.

Official Bank of Canada Valet observations, normalized JSON. Query: ?series=FXUSDCAD,FXEURCAD&recent=5 (1-10 comma-separated codes; FX pairs like FXUSDCAD/FXEURCAD/FXGBPCAD, overnight target rate V39079, prime rate V80691311). recent=N returns the last N daily observations (default 1, max 60). Primary-source CAD reference, published each business day; 6h cache.
