Current tools (18)

base64_decodeDecode a Base64 string into UTF-8 text and report invalid payloads as errors when recovering embedded credentials, tokens, or transport-encoded content. Use when: - Decode this Base64 string to UTF-8 text - Recover plain text from a Base64-encoded payload - Check whether a Base64 string is valid and decode it Do not use when: - Encode plain text to Base64 (use base64_encode) - Decode percent-enc
params: value*
base64_encodeConvert 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. Use when: - Encode this UTF-8 string as Base64 - Convert plain text into standard Base64 for transport - Produce a Base64 representation of a credential or payload string Do not use when: - Decode Base64 back to text (use base64_decode)
params: value*
countries_bulkDownload the complete versioned countries dataset as JSON for caching, offline use, or multi-country analysis when a single country_lookup call is not enough. Use when: - Download the full countries dataset as JSON - Cache the complete versioned countries snapshot for offline use - Analyze or filter many countries without repeated single-code lookups Do not use when: - Look up metadata for a sin
params: version
country_lookupResolve 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. Use when: - What currency and calling code does country code JP use? - Get official name, region, and languages for ISO country CA - Look up standardized metadata for a two-letter ISO 3166-1 country
params: code*
currency_lookupResolve 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. Use when: - What is the symbol and number of decimal places for EUR? - Which countries use currency code JPY? - Get ISO 4217 name and metadata for USD Do not use when: - Convert amounts between currencies or f
params: code*
http_status_lookupExplain 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. Use when: - What does HTTP status 404 mean? - Get the standard name and description for status code 429 - Explain an HTTP response code returned by an API Do not use when: - Decide whether a request succeeded without needing the status n
params: code*
isbn_validateVerify whether an ISBN-10 or ISBN-13 passes checksum rules and return normalized digits when checking book identifiers before catalog or purchase flows. Use when: - Is this ISBN valid? - Check the checksum for an ISBN-13 book identifier - Normalize and validate an ISBN-10 or ISBN-13 string Do not use when: - Look up book title, author, or cover metadata from an ISBN - Validate UUIDs (use uuid_va
params: value*
json_validateParse a string as JSON to confirm it is well-formed and return a normalized representation when possible before further processing or storage. Use when: - Is this string valid JSON? - Parse and normalize a JSON payload before processing - Check whether agent or user-supplied text is well-formed JSON Do not use when: - Validate against a specific JSON Schema or OpenAPI model beyond well-formednes
params: value*
language_lookupResolve 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. Use when: - What language does ISO 639-1 code ja refer to? - Get the native name for language code fr - Resolve a two-letter language code to its English and native names Do not use when: - Translate text between languages - Detect the language of a
params: code*
luhn_validateRun 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. Use when: - Does this number pass a Luhn check? - Validate a payment-card-like identifier checksum - Verify a numeric ID that uses a Luhn check digit Do not use when: - Charge a card, tokenize payments, or call a payment processor - Validate ISBNs (use
params: value*
mime_lookupMap 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. Use when: - What MIME type should I use for a .webp file? - Look up metadata for Content-Type application/json - Resolve a file extension to the correct MIME type for an upload or response header Do not use when: - Sniff or detect M
params: query*
timestamp_convertConvert 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. Use when: - Convert this Unix timestamp to ISO-8601 - Turn an ISO-8601 datetime into epoch milliseconds - Bridge APIs that mix Unix seconds and ISO-8601 strings Do not use when: - Convert a datetime between IANA timezones while preserving the ins
params: value*, input_format*
timezone_convertConvert 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. Use when: - What time is 3pm Toronto in Tokyo? - Convert an ISO-8601 datetime from America/New_York to Europe/London - Show the same instant in another IANA timezone with DST-aware offsets Do not use when: - Only convert between Un
params: datetime*, from_timezone*, to_timezone*
tld_lookupIdentify 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. Use when: - What kind of TLD is .io? - Is .ai a country-code or generic top-level domain? - Get curated metadata for DNS TLD com Do not use when: - Check whether a full domain name is registered or available - Resolve DNS records or WHOIS ownersh
