How to call it

POST https://agents.dexl.io/v1/tools/cve-lookup

Each call costs $0.001 in USDC on Base, paid with the request over x402.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

POST https://agents.dexl.io/v1/tools/cve-lookup
content-type: application/json

{
  "cve_id": "CVE-2021-44228"
}

Parameters

ParameterTypeRequiredDescription
cve_idstringNoExact CVE id, e.g. "CVE-2021-44228"
keywordstringNoFree-text search, e.g. "log4j" or "openssl buffer overflow"
limitintegerNoOnly used with keyword. Default: 5.

Example response

The provider's example. We can't check it without paying.

{
  "cached": false,
  "output": {},
  "units": 1
}

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/cve-lookup' \
  -H 'content-type: application/json' \
  --data-raw '{"cve_id":"CVE-2021-44228"}'

# 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/cve-lookup' \
  -H 'content-type: application/json' \
  --data-raw '{"cve_id":"CVE-2021-44228"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
