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 word count (and potentially token count) for the submitted text. The response schema is open-ended (additionalProperties: true), so additional metadata about the text may be included.
Example use cases
Pre-submission word count check
“Can you count how many words are in this essay draft before I submit it? Here it is: 'Artificial intelligence is transforming the way we work, communicate, and learn. Over the past decade...' [full text]”
Content quota enforcement for agent
“Before sending this generated blog post to the publisher, count the words in it to make sure it hits at least 800 — here's the full text.”
Billing and usage audit
“I need to know exactly how many words are in each of these customer transcripts so I can estimate processing costs — start with this one: 'Hello, thank you for calling support...'”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/words/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.0015 USDC), pay-per-call word count for text up to 50,000 characters and are already operating in an x402/Base payment environment. Prefer it over rolling your own counter when you need a reliable, API-native solution that integrates with autonomous agent payment flows on Base.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty text field returns zero or error
- Payment failure via x402 on Base blocks the call
- Malformed JSON body causes 400 error
- Cloudflare Worker timeout for very large inputs near the character limit
