Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.003.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://bio.halowerk.com/v1/microbiome-diversity' \

  --data-raw '{"taxa":[{"count":430,"taxon":"Bacteroides"},{"count":280,"taxon":"Faecalibacterium"},{"count":140,"taxon":"Roseburia"},{"count":50,"taxon":"Akkermansia"}]}'

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