Applies ordered set/remove attribute and set name/description operations to caller-supplied metadata, then hashes canonical output. It does not mint, sign, upload, mutate an on-chain token, preserve media, or verify ownership.

Derives behaviour classes from on-chain activity: share of swaps, regularity of intervals, hour-of-day spread, counterparty count and contract code. Several classes at once are allowed and usually more accurate than one. Every class carries its evidence; without evidence no class is set. automation_likelihood comes from measurable traits - interval regularity and how evenly activity spreads over the day - listed in features_used, never from a hunch. Limits: this classifies BEHAVIOUR, not people.

Reads token balances of one wallet on several chains from a public index and the native balance from the node itself. The same asset exists on several chains in different versions; canonical and bridged issues are reported separately and still summed, because both together are the answer. Every chain carries its block height, without which the sum cannot be checked. A chain that cannot be reached drops out with a reason under chains_failed and the call stays valid. Limits: the index exists for E

Takes a route as an ordered list of waypoints, samples it at a chosen spacing and tests every sample against the currently active SIGMETs carrying a volcanic ash hazard. For each hit you get the affected segment as a from-to pair of waypoints, the SIGMET issuing centre and flight information region, the validity window, the reported base and top of the ash layer, and the raw text.

WalletTriage — real-time wallet risk check: dangerous ERC20 approvals cross-referenced with a live exploit threat feed. Returns risk_score (0-100), risk_level and actionable findings.

Reads one transaction hash on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain and answers the question an agent actually has: did it go through, is it final yet, and what did it cost. Finality is defined differently per chain, so the rule used and the required block count are part of the answer instead of a single hard-coded number. A hash that no node knows is reported as "unbekannt", never as "fehlgeschlagen" — the two are not the same. A pending transaction whose nonce has alre

Reads the transaction history of one wallet from a public block explorer index and groups it by kind of action. Classification follows the called contract and method, never the amount - a transfer to a known router is a swap, not a payment. Anything that cannot be backed by a method name stays in the category "unbekannt", which is a valid answer here: a large honest remainder beats an invented assignment. Limits: history comes from a public index available for Ethereum, Base, Arbitrum and Optimi

For each node you name — a port, a plant, a corridor, a supplier — the service counts reporting on five disruption themes over a recent window and compares it against the same term own longer baseline. Self-referential comparison is the design: Rotterdam and a regional port have entirely different normal reporting levels, so a fixed threshold is blind for one and a permanent alarm for the other, and only the ratio against a term own history means anything.

Queries public crypto exchanges for one trading pair and returns each venue separately with its last price, bid, ask, spread in basis points, 24-hour high, low and volume, and the age of the value in milliseconds. On top of the raw quotes it computes what a single venue cannot tell you: the median across venues, the spread between the cheapest and dearest venue in basis points, and which venue is the outlier.

Validates a UserOperation structurally and against chain state. It computes the required prefund from the gas limits and fee fields, reads the sender deposit on the EntryPoint and, when a paymaster is set, that paymaster deposit and stake, and says plainly whether the operation is funded. The nonce is read from the EntryPoint and compared with the one supplied, so a stale nonce is caught before submission.

Lists token and native balances of one wallet across chains and prices them where a price exists. priced_pct is mandatory and says how much of the portfolio is actually backed by a price - a total where a third of the holdings have none is not an answer without that number. Tokens that carry the marks of unsolicited airdrops are flagged with the reason but never silently removed; whether they count is the buyer decision. Holdings that cannot be priced appear in unknown_tokens with a reason inste

Reads a Safe from the public transaction service and returns what decides whether it can act: the owner set, the threshold, the current nonce, any enabled modules and the guard contract, and the master copy version. Queued transactions are listed with the confirmations they already carry and the number still missing, so it is visible which of them are one signature away from executing.

Runs the identity resolver, the verification check, the authority scanner and the upgrade risk check against one token and merges them into a single answer. Nothing new is measured here: every statement carries the endpoint number it came from, so any finding can be re-bought individually and checked. A section that fails does not sink the report — it is set to null, listed in checks_failed with its reason, and the score is computed only over the checks that ran, with coverage stated. Sections t

Answers the question that stands before every signature: what really happens to my assets and my rights. The call is executed against the state of a named block on a simulation interface, never on the chain — this hub holds no private key and broadcasts nothing. Balance changes are not inferred from events but measured: the same simulation reads every touched balance immediately before and immediately after the call, native currency included, so an outflow that emits no event is still visible. A

Find tickers by free-text `?search=` (name or symbol) across asset classes via `?market=stocks|crypto|fx|indices` (default stocks), with optional `?type=`, `?exchange=`, `?active=`, `?limit=`. Returns symbol, name, market, exchange, type, and identifiers. Use to discover crypto pairs (X:BTCUSD), FX pairs (C:EURUSD), and index symbols (I:SPX). From x402stock
