How this service works
Left-pad a string to a target width. Call when you need fixed-width IDs or zero-padded codes. Returns padded text and width for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the padded text string and its final width as a JSON object, confirming the output length matches the requested target width.
Example use cases
Zero-padding numeric order IDs
“I need to zero-pad the order ID '1053' so it's always exactly 10 digits wide — can you do that?”
Fixed-width column formatting
“Pad the label 'SKU' with spaces on the left until it's 20 characters wide so it lines up correctly in my report.”
Generating padded hex codes
“Take the string 'ff3a' and left-pad it with zeros to make it exactly 8 characters long.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/pad-leftWhen to prefer
Choose this endpoint when you need a simple, stateless, no-infrastructure string left-padding operation inside an agent pipeline — especially when you lack a local utility function or want to avoid shipping a formatting library. Ideal for zero-padded IDs, fixed-width alignment, or normalizing variable-length codes before storage, display, or downstream processing.
Side effects
- Missing required field (text or width) returns a 4xx error
- Width smaller than or equal to the original string length returns the string unchanged or an error
- Non-integer width value causes a validation error
- Empty fill character may default to space or cause an error depending on API behavior
- Payment failure or insufficient USDC balance prevents the call from completing
