US Census Bureau American Community Survey (ACS) 5-Year estimates for a ZIP code: total population, median household income, median age, and total housing units. ZIP codes map to Census ZCTAs (Census-drawn approximations); some ZIPs (PO-box-only or very new) have no ZCTA match and return 404. Reflects a rolling 5-year survey window, not real-time.

EU VAT number validation (VIES) with predictable behavior for agents. Validates any EU VAT number against the European Commission's VIES service. Two modes: fast validation (may serve a cached result, labeled with its timestamp) and consultation-proof mode (always live, returns the official consultation number, requires requester identification). 'Not confirmed' does not imply the company is invalid. Machine-readable errors with per-member-state availability status.

Finds silent stretches with ffmpeg level detection and shortens each one that exceeds the threshold length. Pauses are shortened to a floor, never removed outright: a pause cut to zero makes the end of one sentence collide with the start of the next, which is a worse defect than the dead air it replaced. The floor defaults to 400 milliseconds, roughly the pause a speaker leaves between sentences, and is settable.

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.

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.
