# BIC/SWIFT Code Structural Validator

> BIC/SWIFT Code Structural Validator is a paid API for AI agents from chainverdict.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Validates a BIC/SWIFT code for structural compliance with ISO 9362, checking character count, bank code, country code, location code, and optional branch code segments.

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 bic-swift-code-structural-validator-a7fdd93d
```

Example prompt: Can you check whether the BIC code DEUTDEDB is structurally valid — does it pass ISO 9362 format rules?

## When to prefer this

Use this endpoint when you need fast, cheap ($0.001) structural validation of a BIC/SWIFT code against ISO 9362 before using it in a payment workflow. Prefer this over the batch endpoint for single-code checks in real-time pipelines. Note: this validates format only — it does not confirm the bank is reachable or that the account exists. Combine with OFAC screening and IBAN validation endpoints on the same platform for a fuller pre-payment check.

## Known failure modes

- BIC code is not 8 or 11 characters — returns validation failure with structural error
- Country code segment does not match ISO 3166-1 alpha-2 format — flagged as invalid
- Non-alphanumeric characters present in BIC — returns parse error
- Missing path parameter — returns 400 or similar client error
- Malformed request or network timeout — returns HTTP error

## How this service works

Validate a BIC/SWIFT code against ISO 9362: 8 or 11 characters, bank and country segments, location and branch codes. Structural only; does not confirm the institution is reachable.

## Output

Returns a structured validation result indicating whether the BIC/SWIFT code passes ISO 9362 structural checks, including whether the code is 8 or 11 characters, and the parsed segments: bank code (4 chars), country code (2 chars), location code (2 chars), and optional branch code (3 chars). Does not confirm the institution is reachable or active.
