# SWIFT/BIC Code Validator

> SWIFT/BIC Code Validator is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0324/call, status unknown (last checked 2026-10-10).

Validates a SWIFT/BIC code by checking format, length, and country code, then extracts the bank code, location code, and branch code.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 api-strale-io-cba53310
```

Example prompt: Can you check if the SWIFT code DABASESX is valid and tell me what bank and location it corresponds to?

## When to prefer this

Use this endpoint when you need instant, cheap, pure algorithmic validation of a SWIFT/BIC code without any external database lookup — ideal for pre-validating user-entered SWIFT codes in payment flows, onboarding forms, or data pipelines. It does not verify whether the bank actually exists in a live registry, only that the code is structurally correct.

## Known failure modes

- Invalid SWIFT format returns validation error with details on which component failed
- Missing or empty swift query parameter returns 400 bad request
- Non-existent or unrecognized country code in the BIC may still pass format validation but flag unknown country
- Payment failure via x402 protocol returns 402 if USDC balance is insufficient

## How this service works

Validate a SWIFT/BIC code. Checks format, length, and country code. Extracts bank code, location, and branch. Pure algorithmic — instant and cheap.

## Output

Returns whether the SWIFT/BIC code is valid along with extracted components: bank code (first 4 characters), country code (characters 5-6), location code (characters 7-8), and branch code (characters 9-11 if present).

## Example request

```json
{
 "swift": "DABASESX"
}
