Public Free API
FormatDock
A lightweight collection of JSON utilities for text, time, URL, JSON, encoding, and hashing tasks. The public release is designed to stay fast, predictable, and easy to verify from scripts or browsers.
Browse by category, copy an endpoint, and start with a practical request. The public free routes are intentionally narrow in scope, deterministic, and rate limited at the edge.
Core
Basic availability
Minimal public checks for a quick liveness probe or a UTC timestamp, not the main utility surface.
Text
Extraction and normalization
Small text utilities for counts, extraction, cleanup, deduplication, and clean slug output.
Slugify Text
Convert a phrase into a clean lowercase ASCII slug.
https://api.formatdock.com/v1/free/text/slugify
Word Count
Return word, character, and line counts for a text block.
https://api.formatdock.com/v1/free/text/word-count
Extract URLs
Pull HTTP and HTTPS links out of plain text.
https://api.formatdock.com/v1/free/text/extract-urls

Text Cleanup
Trim edges and collapse internal whitespace in an input string.
https://api.formatdock.com/v1/free/text/cleanup
Time
UTC and timestamp helpers
Current UTC time, direct conversions, shifting, and a small timestamp difference utility.
Current UTC Time
Return current UTC time and a Unix epoch value.
https://api.formatdock.com/v1/free/time/utc
Unix To UTC
Convert a Unix epoch into an RFC 3339 UTC timestamp.
https://api.formatdock.com/v1/free/time/unix-to-utc
UTC To Unix
Convert an RFC 3339 timestamp into a Unix epoch value.
https://api.formatdock.com/v1/free/time/utc-to-unix

Time Shift
Shift a timestamp forward or backward by a chosen number of minutes.
https://api.formatdock.com/v1/free/time/shift
JSON & Data
Formatting and validation
Simple helpers for validating JSON, making it readable, or compacting it for transport.
Pretty JSON
Pretty-print valid JSON with configurable indentation.
https://api.formatdock.com/v1/free/json/pretty
Minify JSON
Collapse valid JSON into a compact single-line form.
https://api.formatdock.com/v1/free/json/minify
Validate JSON
Check whether JSON is valid and report the top-level type or error location.
https://api.formatdock.com/v1/free/json/validate
Encoding & Hashing
String encoding helpers
Deterministic helpers for SHA-256 and Base64 work.
SHA-256 Hash
Return the SHA-256 hex digest for a string.
https://api.formatdock.com/v1/free/hash/sha256
Base64 Encode
Encode UTF-8 text as Base64 or URL-safe Base64.
https://api.formatdock.com/v1/free/encoding/base64-encode
Base64 Decode
Decode Base64 text back into UTF-8.
https://api.formatdock.com/v1/free/encoding/base64-decode
URL & Web
URL inspection
Inspect URL components, normalize a public URL, or break down a User-Agent string into browser, OS, device, and bot-like hints.
Parse URL
Split a URL into components and query parameters.
https://api.formatdock.com/v1/free/url/parse
Normalize URL
Lowercase scheme and host, remove default ports, and optionally drop fragments.
https://api.formatdock.com/v1/free/url/normalize
Parse User-Agent
Classify a User-Agent string into browser, OS, device type, and a conservative bot-like flag.
https://api.formatdock.com/v1/free/ua/parse
Quickstart
Start with a few direct calls. The practical POST utilities come first; the small GET checks are kept at the end.

FormatDock Pro
Paid email and domain checks are being prepared
FormatDock Pro is being narrowed to the first heavier, network-backed checks that do not belong on the free surface. The first public paid offer is intentionally small and focused on inspecting contact data before you trust it.
- Analyze one email address with syntax, role-like/disposable signals, and domain mail posture in one request.
- Inspect one domain for MX, SPF, DMARC, MTA-STS, TLS-RPT, and BIMI without stitching your own DNS checks together.
- Batch-validate email lists when the job needs more than a single mailbox check.
