How this service works
Pay-per-call API for AI agents: turn any public web page or PDF into clean, LLM-ready Markdown. $0.002 per call in USDC on Base via x402. No API key, no signup.
Output
Returns a JSON object with the operation name ('count'), metadata (chars_in, chars_out, elapsed_ms), and a result object containing: chars (character count), lines (line count), words (word count), and bytes_utf8 (UTF-8 byte size of the input text).
Example use cases
Validate LLM input size limit
“Check if this passage fits within a 100,000 character limit — count the characters and bytes in it: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit...'”
Word count for a draft document
“How many words and lines are in this draft paragraph: 'Artificial intelligence is transforming industries worldwide. Companies are investing heavily in automation and machine learning to stay competitive.'?”
Measure token-adjacent text stats
“Before I send this chunk to the AI, tell me how many characters, words, and UTF-8 bytes it is: 'In the beginning was the Word, and the Word was with God.'”
Technical details
Endpoint
GEThttps://lin-desk-x402.lindesk.workers.dev/v1/texttools/count?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, precise text statistics (character, word, line, and byte counts) for a string — especially useful for validating text against LLM token/character limits, checking content lengths before storage or API submission, or gathering basic readability metrics. Prefer this over client-side counting when operating inside an agent pipeline where a trusted, server-side count is needed.
Side effects
- Missing required 'input' query parameter returns an error
- Input text exceeding 100 KiB limit may be rejected
- Non-text or binary input may produce inaccurate counts
- Payment failure (402) if USDC payment on Base is not completed
