Remove Punctuation API POST

About the Remove Punctuation API

Remove Punctuation works by identifying and removing all standard punctuation characters (including quotes, brackets, dashes, and special symbols) from text. Returns the cleaned text, list of removed characters, and count.

What people use it for

Text Analysis

Clean text data before performing word frequency analysis, sentiment analysis, or natural language processing

Search Optimization

Remove punctuation from search queries to improve matching and relevance in search systems

Data Normalization

Standardize text data by removing punctuation before comparison or deduplication

Content Processing

Clean user input or scraped content by removing punctuation for storage or display

Request parameters — POST /v1/removepunctuation

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

curl -X POST "https://api.apiverve.com/v1/removepunctuation" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text":"Hello, world! How are you doing today? I'\''m great - thanks for asking. This text has lots of punctuation: periods, commas, hyphens & more!"}'

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Response — POST /v1/removepunctuation

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.

Zero-code embed — one snippet, no backend

Drop an interactive Remove Punctuation form onto any page. The widget calls the API for you, so no key ever appears in your markup and there is nothing to deploy.

Changelog — Remove Punctuation API

Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
