How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
Returns a JSON object with three fields: 'digits' (the 6-digit raw sort code string), 'formatted' (the sort code in ##-##-## hyphenated format), and 'valid_format' (a boolean indicating whether the input is structurally valid as a 6-digit sort code).
Example use cases
Pre-payment sort code sanitisation
“I've got a sort code entered by a user — '200000' — can you validate it and reformat it to the standard ##-##-## style before I pass it to the payout system?”
Bulk payout data quality check
“We're about to run a batch of UK bank payouts. Can you check that the sort code 401234 is correctly formatted and structurally valid before we submit?”
User input validation in checkout flow
“A customer just entered '60-16-13' as their sort code during checkout — can you confirm it's valid and give me back the normalised digit and formatted versions?”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/validate/uk-sort-codeWhen to prefer
Use this endpoint when you need a lightweight, fast, format-only check on a UK sort code before passing it to a payout rail or storing it. It does not perform a live bank lookup (e.g. verifying the sort code belongs to a real institution), so pair it with a bank verification service if full validation is required. Prefer this over general-purpose regex checks when you want a standardised, paid-quality normalisation step in an automated agent pipeline.
Side effects
- Input with fewer or more than 6 digits returns valid_format: false
- Non-numeric characters beyond hyphens may cause invalid format response
- Missing sort_code field in request body may return a 400 or validation error
- This endpoint does not verify the sort code exists at a real bank — only format is checked
