x402 APIPassing, checked 3 h ago

Assign text to one of the labels you supply - support tickets, intents, topics, spam or not, anything. The returned label is checked against your list, so the model cannot invent a category: an answer outside your labels is rejected rather than passed through. Comes back with a confidence and a one-line reason. Fixed price per call.

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/classify-text' \
  -H 'content-type: application/json' \
  --data-raw '{"labels":["delivery","billing","technical","other"],"text":"My package never arrived and support is not replying."}'

# 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/classify-text' \
  -H 'content-type: application/json' \
  --data-raw '{"labels":["delivery","billing","technical","other"],"text":"My package never arrived and support is not replying."}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
