How this service works
Check an outbound payout immediately before authorization to catch changed destinations, duplicate payments, amount or currency drift, and malformed payment details.
Output
Returns a structured validation result indicating whether the payout is safe to authorize, along with specific flags for any issues detected — including changed destination warnings, duplicate payment alerts, amount or currency drift, and malformed payment detail errors.
Example use cases
Vendor payment tamper detection
“We're about to send a $45,000 ACH payment to BuildRight Contractors — can you run a preflight check to confirm the bank account on file hasn't changed from what we approved last week and there's no duplicate payment already in flight?”
Crypto payout destination drift
“Before authorizing this 2.5 ETH payout to wallet address 0xA3f9...B12C, check that the destination address matches what was originally set, the amount hasn't drifted, and the payment details aren't malformed.”
Payroll duplicate payment guard
“We're processing payroll for 50 employees today — before we release the batch, run a preflight validation on this payment to Sarah Chen for $3,200 USD to make sure it hasn't already been sent this cycle and the account details are correct.”
Technical details
Endpoint
POSThttps://api.vrsai.tech/v1/capabilities/payout_preflight/versions/1.0.0/executeWhen to prefer
Use this endpoint as a mandatory gate immediately before any outbound payment authorization in automated or agentic workflows. Prefer this over manual review when processing high-volume payouts, when destination details are stored and may have drifted, or when duplicate-payment risk is high. It is especially valuable in pipelines where payment instructions originate from external or AI-generated sources that could be manipulated.
Side effects
- Malformed input body returns a 400-level error with schema validation details
- Payment details that cannot be parsed may return a malformed-detail flag rather than a hard error
- Ambiguous duplicate detection may produce false positives if prior payment history is incomplete
- Network timeout or service unavailability returns a 5xx error requiring retry before authorization
