Validate Aba

Validate a US bank ABA routing number with the Federal Reserve weighted mod-10 checksum (3-7-1) — not just a 9-digit regex.

Overview

Validate a US bank ABA routing number with the Federal Reserve weighted mod-10 checksum (3-7-1) — not just a 9-digit regex. Returns {valid, routingNumber, district (routing-symbol class), reason}. Catches transposed digits in ACH/wire setup that a length check misses. Structure + checksum only; not a bank-directory existence lookup.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i https://api.jarvisclaw.ai/v1/marketplace/api/validate-aba

# 2. Pay it (the SDK signs and retries for you)
curl -H "X-PAYMENT: <signed-payload>" https://api.jarvisclaw.ai/v1/marketplace/api/validate-aba
