NTS BizNo CLIv0.1.0

When onboarding new suppliers, verify their business registration number (b_no) against the NTS database to ensure they are active (계속사업자) and not closed (폐업자) or dormant (휴업자). Automate checks with bulk.sh for batches of up to 100 numbers per API call, filtering invalid checksums locally first to save quota.

Before issuing a 세금계산서 (tax invoice), validate the counterparty's business number and tax type (일반/간이/면세) via the status API. Combine with validate.sh to confirm the representative name and start date, ensuring compliance with Korean tax law and preventing penalties from incorrect invoices.

Regularly audit a legacy supplier list containing thousands of b_no's using bulk.sh. The script filters invalid checksums, then queries NTS to mark entries as active, dormant, or closed. Output JSONL can be piped into csvkit or a database for deduplication and cleanup, reducing risk of working with defunct vendors.

When creating 견적서 (quotes) or 계약서 (contracts) for Korean B2B partners, use the status endpoint to fetch the legal name and tax type, then feed that data into downstream skills like unified-invoice or juso-address-cli to auto-populate forms with NTS-confirmed information.

Before submitting bids on 나라장터 (Korean public procurement), verify that all subcontractor business numbers are valid and active. Use bulk.sh to process a list of b_no's from procurement documents, ensuring compliance and avoiding disqualification due to invalid vendor records.

Offer a monthly subscription that integrates nts-bizno-cli into customer onboarding platforms. Automate business verification for thousands of new partners, charging per verification or flat fee. Upsell by combining with opendart-cli and juso-address-cli for a full Korean KYB suite.

Deploy the CLI as part of an ERP (e.g., SAP, Oracle) integration for Korean subsidiaries. Customize scripts to run nightly supplier audits, flagging changes in tax type or status. Charge a one-time integration fee plus annual maintenance for updates and support.

Aggregate status and validation results for frequently queried businesses, and sell access to a cache of verified data. Offer tiered pricing: free tier (10/day), pro tier (1,000/day), and enterprise (unlimited). Revalidate periodically to maintain freshness.
