Checks one IPv4 address against nine public DNS blocklists at once — SpamCop, UCEPROTECT, PSBL, Barracuda, DroneBL and four more — and returns each list's raw return code plus the reason text the list itself publishes, not a score. Every list is re-checked on each call with its RFC 5782 test entry, so a dead list or one that refuses queries comes back as unavailable instead of reading as clean. Includes the delisting URL for each hit.

Reloadpi — Order status and refund schema. Returns the fulfillment state machine, polling URL, and refund endpoint for any paid order.

Get a global weather forecast for a city/locality name or exact coordinates. Returns normalized day/night or hourly periods worldwide: NOAA/NWS is preferred within supported U.S. coverage for optional station conditions and active alerts, while MET Norway provides an attributed open-data fallback globally.

Send a question about longevity, aging, or lifespan science. Returns a request ID to poll for the AI-generated answer from Aubrai, VitaDAO's decentralized co-scientist.

Clean CSV, TSV, JSON, JSON Lines, or YAML records with collision-safe header normalization, deterministic integrity hashes, and exact transformation counts.

Fetch and normalize public RSS or Atom feeds into stable structured JSON entries for agents and research workflows.

Convert a time between any two IANA time zones, with daylight saving applied from the runtime's own tz database. Returns both sides with their UTC offset, abbreviation and DST flag, plus the UTC instant and the difference in hours. Warns when the time you asked for does not exist or happens twice because the clocks change that day: the two cases that quietly make a hand-made conversion wrong.

Base64 in both directions, including the URL-safe alphabet, with UTF-8 handled properly. Encoding is what carries payloads through headers and JSON, and x402 itself rides on it.

Generate strong random secrets from the platform CSPRNG, with the entropy in bits so you can judge them. Four alphabets, including one with no look-alike characters for anything a human has to read back.

Turns text into natural speech in English, Spanish, French, Chinese, Japanese or Korean in one or two seconds: Deepgram Aura-2 for English and Spanish, MeloTTS for the rest. Returns a hosted audio URL valid for 24 hours (MP3 for English and Spanish, WAV otherwise) plus its size; add inline=true to also get the base64. Up to 2000 characters per call. You are only charged if the audio is delivered. No API key, no account.

Everything DNS says about one domain in a single call: whether it is registered, its A and AAAA addresses, nameservers, MX servers, SPF and DMARC, DNSSEC, and whether it looks parked. Built for going through a list of domains one at a time. Live DNS, no API key, no account.

Converts between wei, gwei, ether and any token decimals using exact integer maths - no floating point, no silent rounding. The mistake that costs real money is being off by a thousand on decimals.

Validates an EVM address and returns it in EIP-55 mixed-case checksum form. Catches typos before you send funds: an address that fails the checksum is almost always mistyped.

The current time in any IANA time zone, in every form an agent needs at once: ISO with offset, 24-hour, 12-hour, weekday, unix timestamp and UTC. It also says whether daylight saving is active right now and what the zone's standard offset is, so a shifted clock can be told apart from a permanent one.

Validate JSON data against a bounded JSON Schema Draft 2020-12 contract for nested objects, arrays, required properties, types, enums, formats, lengths, patterns, and numeric bounds; return deterministic instance and schema JSON Pointers, explicit error truncation, input hashes, and no remote reference resolution.

Use when an agent has several options and no reason to prefer any, and the choice has to be defensible: picks one or more items from the list you send, with or without repeats, and tells you how many it had to choose from. Do not use to order the whole list (/v1/random/shuffle) or to draw a number in a range (/v1/random/number). No API key, no account.

Compare JSON or YAML deterministically and return source hashes plus machine-readable additions, removals, and replacements by path with explicit truncation evidence.

Extract webpage metadata from one public URL: page title, meta description, canonical URL, headings, hreflang, icons, feeds, Open Graph, Twitter Cards, and JSON-LD Schema.org types, with redirect and response provenance plus privacy-safe, publisher-asserted Organization facts with field evidence.

Compare two texts and return structured line additions, removals, and a unified diff.

Remove duplicate CSV, TSV, JSON, JSON Lines, or YAML records using selected identity fields and report the removed count.
