Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://chain-tools.use.x402atlas.com/solana/pda' \

  --data-raw '{"program_id":"11111111111111111111111111111111","seeds":[{"encoding":"utf8","value":"vault"}]}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
