How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the repeated text string (original text concatenated N times), the repeat count, and a schema identifier ('delx/repeat-string/v1').
Example use cases
Padding test data with repeated strings
“Take the string 'abc123' and repeat it 5 times so I can use it as placeholder test data in my pipeline.”
Validating pay-per-result micro-payment flow
“Run a quick test — send 'ping' through the Delx repeat-string endpoint 3 times and confirm I get the repeated output back so I know the x402 payment flow is working.”
Generating repeated banner text
“I need the phrase 'SALE ' repeated 10 times in a single string for a banner label — can you do that?”
