x402 APIPassing, checked 2 min ago

For a KRX stock, the largest daily price moves of the last ~45 trading days, each paired with that day's representative news headlines (with sentiment) and filings within ±2 days, plus the period return. Built from DeepSearch's Korean news knowledge graph. Correlation, not causation — the response says so where evidence is thin.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.1.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://x402.deepsearch.com/v1/context/why-moving/:ticker'

# 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 - 'https://x402.deepsearch.com/v1/context/why-moving/:ticker' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
