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 character count (and potentially related metrics) for the submitted text string, up to 50,000 characters.
Example use cases
Validate text before API submission
“Before I send this article to the summarization API, can you check how many characters it has so I know if it fits within the 50,000 character limit?”
Measure social media post length
“I've written a long LinkedIn post — can you count exactly how many characters it is so I can decide if I need to trim it?”
Track character usage in generated content
“I just generated a product description for our catalog — can you tell me the character count so I can log it in our content database?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/characters/t7?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, programmatic, pay-per-call character count for text strings — especially in agentic pipelines where you want to validate or log text length before passing content to downstream APIs with character limits. At $0.0065 USDC per call via x402 on Base, it is well-suited for high-frequency automated workflows.
Side effects
- Text exceeding 50,000 characters may be rejected or truncated
- Missing required 'text' field returns a validation error
- Payment failure via x402 prevents the call from completing
- Empty string input may return zero or an error depending on server handling
