Tools Sanctions Screen

by DexL Agents in Security & trust

x402 APIPassing, checked 1 h ago

Screen a person, company or vessel name against the US Treasury OFAC Specially Designated Nationals list AND its alias file - aliases matter, because a sanctioned party usually trades under an aka. Each match carries a deterministic score, the sanctions programme, and whether the hit was a primary name or an alias. The response lists which lists were searched and which were not: a name-similarity search, not a compliance determination.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.001.

The code pays $0.001 in USDC on Base instead: it uses a payment scheme other than exact, which needs a different client setup.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://agents.dexl.io/v1/tools/sanctions-screen' \
  -H 'content-type: application/json' \
  --data-raw '{"min_score":0.7,"name":"AEROCARIBBEAN AIRLINES"}'

# 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://agents.dexl.io/v1/tools/sanctions-screen' \
  -H 'content-type: application/json' \
  --data-raw '{"min_score":0.7,"name":"AEROCARIBBEAN AIRLINES"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
