How this service works
Remove punctuation from text. Useful before tokenization, keyword extraction, or fuzzy match prep. Returns cleaned text with punctuation stripped, plus a compact receipt. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
Returns a JSON object containing the cleaned text string with all punctuation characters removed, plus a compact receipt confirming the operation (character counts, processing metadata). No data is retained server-side.
Example use cases
Pre-tokenization text cleaning
“Before I run tokenization on this paragraph, remove all the punctuation: 'The quick-brown fox jumped over the lazy dog! Was it fast? Yes, very fast.'”
Fuzzy match preprocessing pipeline
“I need to prep these customer-entered strings for fuzzy matching — can you strip the punctuation from 'Dr. John Smith, Ph.D.' so I can compare it more reliably?”
Keyword extraction prep
“I want to extract keywords from this review but the punctuation is getting in the way — clean it up for me: 'Absolutely loved it!! Great product... 10/10, would recommend.'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/remove-punctuationWhen to prefer
Choose this endpoint when you need a deterministic, first-party punctuation removal step with no API key or subscription overhead. Ideal for agentic pipelines where you want a pay-per-call micro-operation ($0.001 USDC via x402) without standing up custom string-processing code. Best suited for preprocessing steps before tokenization, fuzzy matching, or keyword extraction where consistent, predictable stripping behavior is required.
Side effects
- Text exceeds 100,000 character limit — validation error returned, no charge
- Missing or null `text` field — structured validation error, no charge
- Empty string input — returns empty cleaned text
- Non-string value for `text` — validation error
