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 padded string (text field showing the result), along with the original parameters (fill character, side, width) and a schema identifier (delx/util-string-pad/v1) for verification.

Example use cases

Zero-pad order IDs for display

“I need to format order number 317 as a 6-digit zero-padded string like 000317 — can you left-pad it with zeros to width 6?”

Right-align labels in fixed-width report

“Right-pad the label 'SKU' with spaces so it fills exactly 10 characters wide, so all my report columns line up.”

Normalize product codes to fixed length

“I have a product code 'A7' and I need it padded with dashes on the right side to reach a total width of 8 characters — can you format it for me?”

Technical details

Endpoint

POSThttps://commerce.delx.ai/api/v1/x402/string-pad?utm_source=zero.xyz

When to prefer

Use this endpoint when an AI agent needs to format strings or numbers to a fixed width (e.g. zero-padded IDs, aligned columns, fixed-length codes) without deploying custom code. Ideal for agentic pipelines that need verifiable, pay-per-use string utilities via x402/USDC with no signup or API key management.

Side effects

Missing required fields (text or width) return a validation error
Invalid side value (not 'left' or 'right') may cause a bad request
Width smaller than the input text length may return the original string unmodified
Payment failure via x402 protocol blocks the request
Non-integer width value causes schema validation error
