## 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 bic-swift-format-validator-1bca8707 -d '<json body>'
```

Example prompt: Can you check whether 'DEUTDEDB' has a valid BIC/SWIFT code shape — I need to validate its format before submitting a payment instruction.

## When to prefer this

Use this when you need a fast, inexpensive BIC/SWIFT format check ($0.004 USDC) and the free sandbox endpoint is not available or has been exhausted. Prefer the sandbox endpoint (POST /v1/sandbox/check-bic) for development or when cost matters. Choose this over manual regex when you want a reliable, maintained format validator without implementing BIC validation logic yourself.

## Known failure modes

- Empty or missing value field returns validation error
- String exceeding 20000 characters rejected by schema
- Ambiguous input not clearly a string may cause parsing failure
- Service unavailable returns HTTP 5xx
- Payment failure (insufficient USDC) blocks the paid endpoint — use free sandbox POST /v1/sandbox/check-bic first

## How this service works

Call when an agent needs whether a string has a BIC/SWIFT shape. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/check-bic first.

## Output

A boolean or structured response indicating whether the submitted string conforms to the BIC/SWIFT format specification (structural/shape check), without performing any live registry or network lookup.
