Maps each two-bit group of caller-supplied UTF-8 bytes to A, C, G or T and reports a SHA-256 checksum of the original bytes. This reversible representation performs no biological synthesis, homopolymer balancing, GC optimization, addressing or error-correcting code.

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/dna-storage-encode' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"HALOWERK deterministic DNA storage demo"}'

# 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://bio.halowerk.com/v1/dna-storage-encode' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"HALOWERK deterministic DNA storage demo"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call
