How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the (possibly truncated) text string under the 'text' key, and a boolean 'truncated' field indicating whether the original text was shortened. If the original text was within the limit, 'truncated' is false and 'text' is unchanged.
Example use cases
Fit tweet-length content
“I need to cut this blog excerpt down to 280 characters for a social post — here it is: 'Our new product line combines cutting-edge materials science with ergonomic design principles honed over a decade of user research, resulting in tools that professional craftspeople say feel like natural extensions of their hands.'”
Clip agent output for UI display
“Trim this AI-generated product description to 150 characters max so it fits in the card preview: 'Handcrafted from sustainably sourced oak with a water-resistant finish, this desk organizer keeps your workspace tidy while adding a touch of natural warmth to any office setting.'”
Enforce database field length limit
“I need to make sure this user bio doesn't exceed 500 characters before saving it — can you truncate it? 'Born in Tokyo and raised across three continents, Sofia has spent the last fifteen years building open-source tools for climate scientists, winning two international awards and mentoring over two hundred early-career researchers worldwide.'”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/text/truncate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, deterministic string truncation with a clear boolean signal indicating whether truncation happened — especially in agentic pipelines where you want to enforce character limits programmatically without writing local code. At $0.001 USDC per call via x402, it's suitable for high-frequency use in autonomous workflows on Base. Prefer it over local truncation logic when your agent runtime lacks string manipulation utilities or you need a consistent, hosted utility callable across different agent environments.
Side effects
- Text exceeds server-side limits (maxLength capped at 50000 characters)
- Invalid or missing 'text' field returns an error
- maxLength below 0 or above 50000 rejected by schema validation
- Payment failure via x402 protocol blocks the call
- Non-string input for 'text' field causes validation error
