Entity Deep Check

by api.limitguard.ai in Company & people data

x402 APIPassing, checked 1 h ago

Extended screening in two tiers. fresh ($0.88): politically exposed person and relative/close-associate (role.pep / role.rca) matches from OpenSanctions, with the match detail the standard entity check does not return, plus a Dutch Centraal Insolventieregister screen (NL only). enhanced ($1.71): the same plus adverse media screening against a global news index. If a source of the requested tier cannot be reached the call returns 503 and is not charged.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.88.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.limitguard.ai/v1/entity/deep-check' \
  -H 'content-type: application/json' \
  --data-raw '{"country":"NL","entity_name":"Acme B.V."}'

# 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://api.limitguard.ai/v1/entity/deep-check' \
  -H 'content-type: application/json' \
  --data-raw '{"country":"NL","entity_name":"Acme B.V."}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
