## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability chainverdict-bic-swift-validation-api-3b54df3e
```

Example prompt: Can you check if the BIC code DEUTDEDB is a valid SWIFT code before I set up this international wire transfer?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.001 USDC) per-call BIC/SWIFT code validation in an automated payment workflow, fintech onboarding flow, or accounts payable process. Prefer it over manual lookups or heavier bank directory APIs when you only need pass/fail validity for individual codes at low cost.

## Known failure modes

- Invalid BIC format (not 8 or 11 characters) returns validation failure
- Unrecognized BIC not found in reference data returns invalid verdict
- Missing BIC path parameter returns 400 or routing error
- Unpaid request returns HTTP 402 with payment requirements
- Network timeout on upstream lookup returns 5xx error

## How this service works

x402 v2 pay-per-call. Unpaid requests receive HTTP 402 with payment requirements.

## Output

Returns a validation verdict indicating whether the provided BIC/SWIFT code is valid, potentially including structured details about the bank identifier such as bank code, country code, location code, and branch code components.
