How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the extracted alphanumeric tokens parsed from the submitted text, with non-alphanumeric characters and sequences removed or separated.
Example use cases
Clean noisy log data for parsing
“I have a messy server log line full of brackets, dashes, and colons — can you pull out just the alphanumeric tokens so I can search through them? Here's the line: '[ERROR] 2024-03-15T09:12:03Z :: host=srv-01 code=ERR_500 msg=timeout!'”
Tokenize user input for keyword matching
“Take this user-submitted search query and extract only the alphanumeric tokens so I can match them against our keyword index: 'best coffee & tea shops — 2024 edition!!!'”
Strip symbols from scraped product codes
“I scraped a product listing and it has a lot of punctuation and symbols mixed in. Can you pull out just the alphanumeric sequences from this text? Here it is: 'SKU: AB-4421/X, Ref# [C99-02], Batch: **XZ_001**'”
