}

{
  "summary": "- The ECB left interest rates unchanged.\n- Inflation is easing.\n- Trade-tariff uncertainty remains."
}

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

The code pays $0.01 in USDC on Base instead: the x402 libraries don't pay USDC by default.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.vextorium.com/v1/summarize' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"Summarize in 3 bullet points: The European Central Bank kept interest rates unchanged on Thursday, citing easing inflation but persistent uncertainty over trade tariffs."}'

# 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.vextorium.com/v1/summarize' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"Summarize in 3 bullet points: The European Central Bank kept interest rates unchanged on Thursday, citing easing inflation but persistent uncertainty over trade tariffs."}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
