Biology Protein Sequence Descriptors

by Protein sequence descriptors in AI models & inference

x402 APIPassing, checked just now

Calculate composition, molecular mass and model-based charge descriptors from supplied protein sequences. For dataset analysis; not a folding or function prediction. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.013003.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://www.mahastrategies.com/api/v1/compute/biology/protein-sequence-descriptors' \
  -H 'content-type: application/json' \
  --data-raw '{"dataClass":"synthetic","sequence":"ACDE"}'

# 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://www.mahastrategies.com/api/v1/compute/biology/protein-sequence-descriptors' \
  -H 'content-type: application/json' \
  --data-raw '{"dataClass":"synthetic","sequence":"ACDE"}' \
