How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A structured JSON object containing the extracted alphanumeric tokens parsed from the input text, with special characters, punctuation, and whitespace removed or used as delimiters, leaving only sequences composed of letters (a-z, A-Z) and digits (0-9).
Example use cases
Clean log file for parsing
“I have this server log full of special characters and brackets — can you extract just the alphanumeric tokens from it so I can analyze the keywords and error codes? Here's the text: '[ERROR] :: conn-timeout!! at host=db.prod.example.com; retries=5 failed.'”
Tokenize user-submitted form input
“Take this user-submitted text and strip out everything except letters and numbers — I need just the clean alphanumeric tokens for downstream keyword matching: 'Hello! I'm interested in model #A7-X2, price: $499.99 (sale!!)'”
Extract identifiers from raw document
“Parse this raw contract snippet and give me only the alphanumeric tokens — I need to pull out all the reference codes and words without any punctuation or symbols cluttering things: 'Contract ID: #REF-2024/007 — signed @ 10:45am, parties: Acme-Corp & Beta_LLC.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/alphanumeric/t7?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, fast, pay-per-call alphanumeric tokenization step for agent pipelines — ideal when you want to strip punctuation and symbols from text up to 50,000 characters without spinning up a local NLP library. At $0.0065 USDC per call it suits high-volume autonomous agent workflows billed via x402 on Base where serverless micro-payments are already integrated.
Side effects
- Empty or whitespace-only input may return an empty token list
- Text exceeding 50000 characters will be rejected with a validation error
- Non-string input type for 'text' field will cause a schema validation error
- Payment failure via x402 (insufficient USDC balance) will result in a 402 response before processing
- Network timeout on the Cloudflare Workers edge may return a 5xx error
