Agent Bits
Machine-readable utilities and datasets for AI agents.
Capabilities
base64_decode
Decode a Base64 string into UTF-8 text and report invalid payloads as errors when recovering embedded credentials, tokens, or transport-encoded content.
base64_encode
Convert a UTF-8 string into standard Base64 when you need a portable text encoding for credentials, binary-safe transport, or embedding data in JSON/HTTP fields.
countries_bulk
Download the complete versioned countries dataset as JSON for caching, offline use, or multi-country analysis when a single country_lookup call is not enough.
country_lookup
Resolve an ISO 3166-1 alpha-2 country code (for example CA, US, JP) to official name, region, currency, calling code, languages, and related country metadata when you already have the two-letter code.
currency_lookup
Resolve an ISO 4217 currency code such as USD, EUR, or JPY to its name, symbol, decimal places, and which countries use it when you need currency metadata rather than a live exchange rate.
http_status_lookup
Explain what a numeric HTTP status code such as 404 or 429 means by returning its standard reason phrase and a short description for debugging or API responses.
isbn_validate
Verify whether an ISBN-10 or ISBN-13 passes checksum rules and return normalized digits when checking book identifiers before catalog or purchase flows.
json_validate
Parse a string as JSON to confirm it is well-formed and return a normalized representation when possible before further processing or storage.
language_lookup
Resolve an ISO 639-1 language code such as en, fr, or ja to its English name and native name when you need language metadata from a two-letter code.
luhn_validate
Run the Luhn checksum on a numeric string such as a payment-card-like identifier to verify the check digit before accepting or storing the value.
mime_lookup
Map a file extension such as webp or png, or a MIME type string, to curated Content-Type metadata when setting headers, validating uploads, or choosing a media type.
timestamp_convert
Convert Unix epoch seconds or milliseconds to ISO-8601, or an ISO-8601 datetime to Unix epoch values, when bridging APIs that disagree on time formats.
timezone_convert
Convert an ISO-8601 datetime from one IANA timezone to another while preserving the same instant, including daylight-saving-aware wall times such as Toronto to Tokyo.
tld_lookup
Identify what a DNS top-level domain such as com, io, or ai is classified as and commonly used for when classifying domains or answering TLD questions.
unit_convert
Convert a numeric value between supported length, mass, or temperature units—for example miles to kilometers or Celsius to Fahrenheit—when you need a deterministic unit conversion.
url_decode
Decode a percent-encoded URL component into plain text when reading query parameters, path segments, or form values that contain escaped characters.
url_encode
Apply encodeURIComponent-style percent-encoding so query parameters, path segments, or form values are safe to place in a URL.
uuid_validate
Check whether a string is a well-formed UUID and, when recognizable, report its version and variant so you can accept or reject identifier inputs confidently.
