Lei Resolve

x402 APIPassing, checked 4 h ago

Resolves in both directions: a 20-character LEI returns that entity, a company name returns the matching entities ranked by the search. Each result carries the registered legal name, legal form, jurisdiction, registered address, the local register and registration number, and the LEI registration status with its last update and next renewal date — a lapsed registration means nobody renewed it and the data may be stale, which is stated rather than left to be discovered.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://finanz.halowerk.com/v1/lei-resolve' \
  -H 'content-type: application/json' \
  --data-raw '{"lei":"W38RGI023J3WT1HWRP32"}'

# 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://finanz.halowerk.com/v1/lei-resolve' \
  -H 'content-type: application/json' \
  --data-raw '{"lei":"W38RGI023J3WT1HWRP32"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
