Looks up a legal entity in GLEIF, the worldwide Legal Entity Identifier register, by LEI or by name, and turns the raw record into an answer. GLEIF returns keys rather than statements: the legal form arrives as a code like 6QQB and the register as RA000304, so both are resolved against the GLEIF code lists into the legal form in its own language and the competent register with its website.

Runs each step separately as a simulation (eth_call with state override) against the current chain state and reports each result on its own, so a token that can be received but not moved on is visible as exactly that. Nothing is ever executed: no transaction is broadcast, no key is held, no approval is given. Limits, and they are decisive: can_buy and can_sell through a DEX router are NOT simulated - that needs a funded account and a router path this service cannot back, so both stay null. What

Returns scheduled economic-data release dates from the Federal Reserve Bank of St. Louis for a caller-selected window of at most 366 days. Results can be restricted by release id or searched by release name and include the publisher link and press-release flag from the FRED release directory. This is an on-demand calendar lookup, not a mirror or bulk export. Dates are source publication dates and do not guarantee that observations are already available in FRED.

[BATCH+PROOF] x402 service graveyard - services that vanished from the census. THRESHOLD stated plainly: listed on FIRST confirmed absence (confirm_absences=1), NOT multi-day confirmation - only two snapshot days exist, which cannot support a streak test. Rows are hash-backed and recompute offline with ?verifiable=1; record_hash_verifiable reports the exact count per response. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.09 per call.

Takes a chain key and a contract address, or one of a short list of globally unambiguous symbols. A symbol that is not on that list is refused with 400 and a pointer to the address rather than resolved to a guess: the same ticker exists on every chain, and the imitations carry it deliberately. price_usd, decimals and symbol come from the source as they are. confidence is passed through unsmoothed, and this is the point of the endpoint: where the source omits the field, the answer carries null an

Answers the two questions that open any serious piece of research. First, where does something stand officially: filter a curated directory of authorities, registers, standards bodies and intergovernmental organisations by subject and country and get, for each one, what it is actually authoritative for, which is the real answer rather than a bare list of links.

Splits the answer into sentences and measures, for each one, how much of it is covered by the supplied sources. Coverage is asymmetric on purpose: the question is what share of the statement appears in the source, so a long source can fully cover a short claim, and it combines single-word overlap with word-pair overlap because the same words in a different order can mean something else. Two checks override coverage and this is the point of the endpoint.

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

Loads a public https page, finds the requested form, fills your values into it in a real headless browser and reports what a submission would run into — without submitting. Each field is checked against what the page itself declares: whether it is required and empty, whether the value matches the field type for email, url, number, tel, date, time and color, and whether a select value is one of the offered options.

Crypto wallet sanctions & compliance screening (AML/KYT): screen any EVM/Solana/Bitcoin/Tron/XRP wallet against the official OFAC SDN crypto list (UN/UK declared) with mixer (Tornado Cash) exposure and wallet age, returning PASS/WARN/BLOCK and a cryptographically SIGNED compliance receipt (list-version-pinned, verifiable offline) for audit. OFAC wallet check, travel-rule / KYT counterparty screening with an auditable attestation an agent can keep.

Uniswap Trading API quote with on-chain oracle price comparison. Drop-in proxy for Uniswap /quote — same request body, response includes priceFeedExists, deltaBps, and oracleAmount.

Accepts three forms of recipient. A bech32 lnurl is decoded to its callback URL, a Lightning address is resolved through the well-known lnurlp path, and a Nostr public key is resolved by reading its kind 0 profile from relays and taking the lud16 or lud06 field it publishes.

Does two things that every shipping integration rebuilds and every one of them differently. First, carrier detection: the number is matched against the known formats and, where the format carries one, the check digit is actually computed — the UPS 1Z digit, the Universal Postal Union S10 digit and the GS1 mod-10 digit. This matters because pattern alone does not separate the formats: twelve digits can be DHL Paket or FedEx, fourteen can be GLS, DPD or Hermes.

Measures how much bridged capital sits on a chain and how that changed. bridged_usd is the sum of canonical and external value: what came in over the canonical bridge of the chain plus what third party bridges brought, while natively issued value is reported apart because it never crossed a bridge. net_usd carries its sign meaning in a field of its own, positive always means capital moved INTO the queried chain. inflow_usd and outflow_usd are the summed positive and negative steps of the sampled

Collects kind 9735 zap receipts addressed to one public key over up to twelve relays, merges them by event id and reports who sent how much over the requested window. Every amount comes from decoding the BOLT-11 invoice carried in the receipt, not from the amount tag of the zap request, because the two can disagree and only the invoice was payable.

Fetches one public policy page in a real browser and turns it into a fixed schema: return window in days and what it counts from, who pays the return shipping, how the refund is issued and within how many days, any restocking fee, the required condition of the goods, the excluded product categories, the steps of the procedure, whether an RMA is needed, the contact route and whether a statutory right of withdrawal is mentioned.

Resolves in both directions: a 20-character LEI returns that entity, a company name returns the matching entities ranked by the search. Each result carries the registered legal name, legal form, jurisdiction, registered address, the local register and registration number, and the LEI registration status with its last update and next renewal date — a lapsed registration means nobody renewed it and the data may be stale, which is stated rather than left to be discovered.
