Software developer — developer tooling, HTTP APIs and open-source experiments.

About me

I build small, well-documented developer tools and open standards integrations. Current focus: the x402 HTTP payment protocol (an open standard for machine-readable 402 responses) and JSON/CSV data tooling.

Open-source projects

x402-toolbox — open-source Python toolkit implementing an x402-compliant utility API server: CSV/JSON conversion, hashing, schema validation and text tools behind a single HTTP interface.

is-a.dev domain config — DNS configuration for this page via the community is-a.dev register.

Data utilities — a set of small, composable CLI/HTTP utilities I maintain for data-wrangling work:

x402 integration demo (free, non-commercial)

As part of learning the x402 open protocol, my toolbox server exposes a free public demo endpoint. It is a technical demonstration only — no products are sold and there is no pricing or checkout; it simply shows how a standards-compliant HTTP 402 challenge/response works:

# any request returns a machine-readable x402 challenge (demo)
curl -s https://hasned.is-a.dev/x402/demo/csv2json -X POST \
  -H 'Content-Type: application/json' -d '{"csv":"a,b\n1,2"}'

Response: a JSON accepts manifest describing the payment requirement, per the x402 spec. This is documentation of an open standard, not a commercial offering.
