Business Batch

by Korea Business Verify (KBV) in Company & people data

x402 APIPassing, checked 24 min ago

Screen a supplier list against two registries at once: check up to 100 companies per call, $0.02 per number, and get registration status plus any public-procurement debarment on record. A company can be active and still barred from public contracts, so the summary counts how many are currently debarred. Live Korean National Tax Service and Public Procurement Service data.

Call it from code

The curl command shows the payment challenge.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://kbv-server-f7vfitmlkq-du.a.run.app/v1/business/batch' \
  -H 'content-type: application/json' \
  --data-raw '{"business_numbers":["124-81-00998","123-45-67890"]}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://kbv-server-f7vfitmlkq-du.a.run.app/v1/business/batch' \
  -H 'content-type: application/json' \
  --data-raw '{"business_numbers":["124-81-00998","123-45-67890"]}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode

We don't show code that pays this service: it uses a payment scheme other than exact, which needs a different client setup.
