Slugify

POST /api/slugify1 quota unit per call · cache hits free

Generate URL slugs from arbitrary strings. Lowercases, transliterates accented characters, strips punctuation, and replaces whitespace with hyphens.

Converts a string into a URL-friendly slug: - Lowercases (configurable). - Transliterates accented characters (`é` → `e`, `ß` → `ss`, Cyrillic / Greek / etc. → closest Latin equivalent). - Strips punctuation. - Replaces runs of whitespace with a single separator (default `-`). Useful for blog-post URLs, GitHub-style anchor IDs, predictable filenames from user-supplied titles.

Inputs

Name	Type	Default	Description
input*	string	—	Text to slugify.
separator	string	"-"	Joiner between words (typically `-` or `_`).
lowercase	boolean	true	Lowercase the output.
decamelize	boolean	true	Split `camelCase`/`PascalCase` into separate words first.
preserveCharacters	string	—	Characters from this string are preserved literally instead of replaced (e.g. `_/` to keep underscores and slashes).

Response

Modes: json, text. Cache: yes (24h TTL).

Every response carries x-cache (HIT / MISS / BYPASS), x-cache-signature (stable across identical inputs), and the rate-limit headers listed below.

Quota & limits

Cost per call	1 unit against the 10,000-unit monthly quota. Cache hits are free — only cache misses decrement.
Burst limit	200 requests per rolling minute, shared across all tools.
Max request size	`64 KiB` (base64 inflates file payloads ~33% — the limit applies to the decoded bytes).
Max response size	`128 KiB`
Timeout	5s wall clock.
Rate-limit headers	`X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Burst-Limit` on every response; `X-Quota-Warning` once 80% of the monthly quota is spent; `Retry-After` on 429s.

Errors

Errors are JSON with an error string; schema failures add a details object (Zod's flattened field errors).

Status	When	Body
400	Input fails the tool's schema (wrong type, missing required field, malformed base64) or the file bytes can't be parsed as the expected format.	{ "error": "invalid inputs", "details": { "fieldErrors": { … } } }
401	Missing or invalid X-Api-Key / X-Account-Id headers (or no session when called from the browser).	{ "error": "unauthorized" }
404	Unknown tool id, or calling /api/* on the website hostname instead of api.xtract.bot.	{ "error": "not found" }
413	Request body over the tool's max request size, or an image header declaring more megapixels than the tool's pixel budget.	{ "error": "…exceeds maxRequestBytes…" }
415	Content-Type isn't application/json on the json-body transport.	{ "error": "unsupported content-type; expected application/json" }
429	Monthly quota or the 200/min burst limit exhausted. Check Retry-After and the X-RateLimit-* headers.	{ "error": "monthly quota exceeded", "monthRemaining": 0, … }
5xx	Conversion engine failure. Safe to retry; if it persists, the input is hitting a bug — please report it.	{ "error": "…" }
