Hex encode or decode text — hex string encoder/decoder.

Base64 encode or decode a string — base64 encoder/decoder (body {mode:encode|decode,input}).

World clock and timezone converter — convert timezones (timezone convert) for the current time or any instant (`at`) in IANA zones (`tzs`, e.g. Europe/London,Asia/Tokyo) or a fixed utc_offset (+05:30…

Validate an IBAN (international bank account number) — check the country, length and ISO 13616 mod-97 checksum; returns validity, country and check digits.

URL encode or decode a string (percent-encoding) for query, path or fragment.

Generate a random UUID (uuid v4, RFC 9562) — 1..100 per call; format uuid|urn|hex|int.

Config Format Convert: JSON, YAML, TOML, INI, .env — Converts a config file between JSON, YAML 1.2, TOML 1.0, INI and .env with every key, value and type kept, and answers with the converted document only, no code fence. Strings that look like other things are quoted so they stay strings (the text 1.10, 007, 01234, no, null, an empty string, a date in quotes), a YAML 1.10 stays the number 1.1, aliases are expanded, TOML dates become their exact text in JSON and INI, scalars are placed before ta…

Evidence-backed, directed compatibility answers for console and PC streaming setups, including console-to-capture-card and capture-card-to-computer connections where evidence exists. Owner-tested observations are scoped; manufacturer-documented routes are not owner tests, and unknown evidence is not incompatibility.

Contact Verify (verify-x402) phone lookup: carrier line type (mobile, landline, VoIP, toll-free) and E.164 format. Detect VoIP/burner numbers in sign-up fraud checks; confirm SMS-capable mobiles. $0.02.

Contract read on Arc: one view call on any contract, decoded, with block and time. ?address=0x...&fn=function balanceOf(address) view returns (uint256)&args=["0x..."] (args a JSON array, optional; &block=N for a past block). For agents that check owner, paused, allowance or a balance before acting, without running an RPC. Only view/pure functions; a revert, a non-contract or a bad signature is refused before payment.
