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 alphanumeric tokens extracted from the input text, with non-alphanumeric characters removed or used as delimiters. The exact structure is flexible (additionalProperties: true), but typically includes the tokenized result derived from the submitted text.
Example use cases
Clean user-submitted form input
“I have this messy user input with a bunch of special characters and punctuation: 'John D0e!! -- address: 123 Main St., Apt #4B'. Can you strip it down to just the alphanumeric tokens?”
Preprocessing text for ML pipeline
“Before I run my classifier, I need to tokenize this document and keep only the alphanumeric parts — here's the raw text: 'The price was $49.99 (inc. tax!) for order #ORD-20240101.' Can you extract just the alphanumeric tokens?”
Sanitizing log data for indexing
“I've got a raw server log line with lots of punctuation and symbols: '[2024-01-15T08:32:11Z] ERROR: connection refused at 192.168.1.1:8080 — retry #3'. Pull out just the alphanumeric tokens so I can index them cleanly.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/alphanumeric/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call ($0.001 USDC) alphanumeric tokenization step for agentic pipelines on Base/x402 infrastructure, especially when preprocessing text before downstream NLP, search indexing, or data cleaning tasks. Prefer it over heavier NLP APIs when you only need simple alphanumeric extraction without semantic analysis.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Payment failure via x402/USDC — 402 Payment Required returned
- Empty text input — may return empty token list or validation error
- Malformed JSON request body — 400 Bad Request
- Network timeout on Cloudflare Worker edge — retry recommended
