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
A JSON object containing a 'results' array with one entry per input item, each showing the operation type, a boolean 'ok' flag, and operation-specific validity details. Also includes a 'summary' object with total, succeeded, and failed counts across the batch.
Example use cases
Pre-flight check for payment batch
“I have a list of 30 IBANs from our payment file — validate all of them in one go and tell me which ones are invalid before we process the transfers.”
Mailing list hygiene before campaign
“I've got 45 email addresses from our newsletter sign-up form — run them all through a batch validation and give me a count of how many are syntactically valid.”
Onboarding form multi-field verification
“Before we create these 15 new accounts, check each user's email, phone number, and card number (Luhn) all in one batch call and stop as soon as any item fails.”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/validate/batchWhen to prefer
Prefer this endpoint over single-item validation endpoints when you need to validate 5 or more items, especially of mixed types (email + IBAN + phone + Luhn + JSON schema). It is more cost-efficient than N sequential calls and returns partial per-item results so one failure does not block the rest.
Side effects
- Array exceeds 50 items — request rejected
- Malformed item missing required 'op' field — per-item error returned
- Invalid IBAN format that cannot be parsed — item marked failed with reason
- stop_on_error=true causes early termination after first failing item
- Payment failure via x402 — entire request not processed
- Unsupported op type — item returns error
