Every agent-payable API.

Turns SenML (JSON or CBOR) and LwM2M TLV into one record shape: resolved name, unit, absolute timestamp, typed value. Optionally puts every series on a shared time axis with a chosen interval and fill rule (last value, bucket mean, linear). Works only on the payload you pass: no device is contacted, nothing is stored, the same request returns the same bytes. TLV carries no type on the wire; unmapped resource ids come back as opaque base64 with a warning instead of a guess.

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.

Battery, EV, and trading agents buy this endpoint to receive calibrated 2h/4h/6h negative-price probabilities, reviewed threshold profiles and an executable response policy.

Aktuelle CO2-Intensität des deutschen Strommix.

Cheapest end-to-end x402 purchase test. Always returns a 402 challenge without payment and the current full NegPrice decision after a valid USDC payment.

Trading and dispatch agents buy this endpoint to obtain the current German EPEX spot price for immediate decisions.

Combined share of permanent water, herbaceous wetland and mangrove classes. The service evaluates a 60 metre local analysis grid around one coordinate and returns standardized units across all 30 covered countries.

Checks one address on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain against the open verification registry and against the chain itself. For a proxy the answer is deliberately split in two: whether the proxy is verified says almost nothing, whether the implementation it currently points to is verified is the real question, and both are reported separately with the implementation address read from the EIP-1967 storage slot, the EIP-1167 clone pattern or an implementation() call —

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

Reads the public perpetual data of Binance USDⓈ-M Futures, Bybit linear and OKX swaps for one BASE/QUOTE pair. Settlement intervals differ per exchange and per contract, so annualized_pct is only computed after normalising to the interval that exchange actually uses, and the formula is part of the answer. current_rate and predicted_rate are strictly separate: where an exchange publishes no forecast, predicted_rate stays null and the reason is named instead of reusing the current rate. next_settl

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

Answers the timing question an agent has before it schedules anything against a regulated exchange: is the main session running, and if not, when does it start. Covers XETR, XFRA, XNYS, XNAS, XLON, XPAR, XAMS, XSWX, XTKS and XHKG with pre trading, main session, post trading, half days and the holidays of 2026 and 2027. Time zones are resolved through IANA names and Intl at the queried instant, never through a fixed offset to UTC, because summer time starts and ends on different dates in the Euro

Asks every known facilitator what it supports and measures how long that answer takes. Reachability, supported chains, supported assets, supported schemes and the current response time are measured live on every call. Limits, and they are the important part: error rate over 24 hours, uptime over 7 days and latency percentiles CANNOT be delivered. They require a series of own measurements every few minutes, and this service keeps no such series - a single call cannot produce a p95. Those fields s

Checks vouchers of a payment channel by computation only - nothing is ever claimed, redeemed or refunded. Signatures are verified cryptographically against the address each voucher claims to be signed by, in EIP-712 form when the typed data is supplied, otherwise as a plain message signature. Double spending is the expensive case and is checked in full: every voucher id occurring more than once is reported with all its occurrences and whether the duplicates agree on the amount. Sums are added up

Compute a keyed HMAC of some data with a secret key — the standard way to sign and verify webhooks (Stripe, GitHub, etc.) and API requests. Data and key may each be utf8/hex/base64/base64url; the tag is returned as hex/base64/base64url.

HMAC of a message under a key — Genesis402 / UnyKorn Operator Network

Generate an RFC 4226 counter-based HMAC one-time password from a base32 secret and counter. Configurable digits (6–10, default 6) and algorithm (SHA1/SHA256/SHA512, default SHA1). An invalid base32 secret is a clean 400.

Map a short product description to likely HS chapter/heading hints (electronics, apparel, coffee, pharma, …). Keyword table only — not a binding customs classification; confirm before filing.

Tokenizes each claim and its supplied evidence, removes a small declared English stop-word list, and reports the fraction of unique claim tokens present in evidence. Coverage below a supplied threshold is flagged. This is lexical grounding screening only: overlap does not prove truth, low overlap does not prove hallucination, and the service does not retrieve or validate evidence.

Hamming distance — the number of positions at which two EQUAL-LENGTH strings differ — plus a normalized similarity. Strings of unequal length are a clean 400.

Generate a random handshake sequence (numbers and symbols) for secure connections.

Adds simple degree-days from caller-supplied daily temperatures to an existing accumulation, then marks days that meet a supplied maturity threshold, crop-moisture interval and maximum rain constraint. It does not obtain a forecast, model crop physiology, inspect a field or guarantee harvestability.
