How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with a single boolean field 'matches' indicating whether the provided text ends with the specified search string (e.g. {"matches": true}).
Example use cases
File extension validation
“Check if the filename 'report_final.pdf' ends with '.pdf' so I can confirm it's the right file type before processing.”
URL suffix detection
“Does the URL 'https://example.com/page.html' end with '.html'? I need to know if it's an HTML page.”
Sentence punctuation check
“Tell me whether the sentence 'Is anyone there?' ends with a question mark — I'm validating user input formatting.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/text/ends-with?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call suffix check on a string without spinning up custom code. Ideal for autonomous agents that need deterministic string validation at minimal cost ($0.0009 USDC) via x402 on Base, especially in workflows where installing a local string library is impractical.
Side effects
- Missing 'text' or 'search' field in request body returns an error
- Empty string inputs may produce unexpected match behavior
- Payment failure via x402 prevents the call from completing
- Network timeout on the Cloudflare Worker edge
