Paid: 0.001 RLUSD per call via x402 on XRPL mainnet (xrpl:0), or 0.001 USDC on Base (eip155:8453). Pay per call, solves one question: Which IANA time zone contains this latitude and longitude, and what is its UTC offset at this instant? The IANA zone id(s) whose boundary contains one point (timezone-boundary-builder data, ODbL 1.0, (c) OpenStreetMap contributors, via geo-tz) with UTC offset and abbreviation at an instant (default now; tzdata from the server runtime). One point per call. Boundaries can be wrong or disputed near borders and at sea; not legal-time, travel or navigation advice. Without payment this returns isError with the x402 PaymentRequired object (fresh invoiceId); retry with the signed payload in _meta["x402/payment"] or the payment_signature argument. Unpaid calls cost nothing.

Response headers (set-cookie values redacted) and the SHA-256 of up to 2 MiB of the body from one anonymous GET, with source and observed_at. The body is never returned. Public http(s) URLs on ports 80/443 only; max 3 redirects; no verdict. Without payment this returns isError with the x402 PaymentRequired object (fresh invoiceId); retry with the signed payload in _meta["x402/payment"] or the payment_signature argument.

Paid: 0.001 RLUSD per call via x402 on XRPL mainnet (xrpl:0), or 0.001 USDC on Base (eip155:8453). Pay per call, solves one question: What is the UTC time according to the NIST Internet Time Service right now? One shared NTP reading of time.nist.gov (refreshed at most every 30 s) with offset, round-trip and stratum shown, plus source and observed_at. NIST describes UTC(NIST) as realized from an ensemble of atomic clocks; this is a network-estimated reading, not NIST-certified or traceable, and not for safety-critical, legal-timestamp or settlement use. Without payment this returns isError with the x402 PaymentRequired object (fresh invoiceId); retry with the signed payload in _meta["x402/payment"] or the payment_signature argument. Unpaid calls cost nothing.

Paid: 0.001 RLUSD per call via x402 on XRPL mainnet (xrpl:0), or 0.001 USDC on Base (eip155:8453). Pay per call, solves one question: What payment terms does this URL advertise in its x402 response? The raw x402 payment-required fields (header and/or JSON body) a URL advertises to one anonymous GET, as received, with source and observed_at. Never pays or signs anything. Public http(s) URLs only; no safety, price or seller verdict.
