Heinrichs Software Solutions Company helps agencies, prime contractors, and businesses build, integrate, test, and maintain dependable applications. Each engagement is bounded by defined deliverables, documented acceptance criteria, and a practical engineering handoff.
Hover or tap an electron to see what we have built.
This calls our production gateway right now, from your machine, and prints the raw
HTTP 402 Payment Required challenge it returns. Nothing here is pre-recorded.
The accepts array is the list of payment options an AI agent can choose from
on a single request. The equivalent curl is printed beside it so you can
reproduce the exact same result in your own terminal.
Press "Run the live 402" to call https://app.heinrichstech.com/v1/cdp/echo and print the challenge this page receives.
curl -s -X POST https://app.heinrichstech.com/v1/cdp/echo \ -H 'content-type: text/plain' \ -d 'hello' | jq .
The gateway answers unauthenticated requests with a 402 challenge, so this costs nothing and moves no funds. Paying the challenge and retrying is what returns the response body.
We give evaluators specific evidence for specific claims. Public documentation, runnable demonstrations, selected source repositories, and dated delivery records are labeled by evidence type so a buyer can see what is proven, what is founder-developed, and what remains private.
Every engagement starts with a scoping conversation, with no obligation, no deck, and no sales pitch.
Two ways a federal buyer or prime can start with a bounded workstream.
A certified set-aside partner that can actually build, with proof on the table before you award.
We are an SBA-certified Service-Disabled Veteran-Owned Small Business and a Florida corporation, registered and active in SAM.gov with confirmed primary NAICS 541511. Qualifying requirements may use SDVOSB set-aside or sole-source procedures when the contracting officer determines the applicable conditions are met.
Our delivery runs on a multi-agent AI engineering capability we built and operate ourselves. It parallelizes research, build, test, and review, so work advances on every front at once instead of queueing behind a single pair of hands. An engineer still owns the architecture, the security posture, and the final call on everything that ships.
We keep each claim tied to the right kind of evidence: public code where available, live demonstrations where appropriate, and dated test or review records for private implementations. You can evaluate the relevant engineering before award without being told that every artifact is public.
From requirement to sustained system in three clear phases, whether we prime the work or perform it under yours.
We read the requirement, confirm fit against our NAICS and our shipped work, and shape a clear technical approach. If a set-aside or sole-source path applies, we map it. You get a straight answer on whether we are the right partner.
We perform in house wherever we hold the depth, and where a requirement is broader than one shop we assemble and lead a vetted team, holding prime responsibility and quality. Our AI engineering harness keeps the pace high across every workstream.
We ship with documentation, security hardening, and a clean handoff, then sustain the system under option years or a support arrangement. You get a contractor that stays accountable for the thing it built.

Our payment gateway answers a single HTTP 402 with eight payment options across Base, XRPL, Stellar, and XRPL EVM. You do not have to take that on faith. Call the endpoint yourself and read the accepts array that comes back.
Four delivery domains supported by clearly labeled public documentation, demonstrations, reference code, or private technical-review material.
Full-stack applications, APIs, and modernization of legacy systems. Node.js, TypeScript, Python, React, on serverless and containerized infrastructure.

Learn more →AWS serverless and containerized architecture, GovCloud-ready patterns, infrastructure as code, and secure CI pipelines with scanning on every build.
Learn more →Production payment infrastructure for machine-to-machine commerce, proven by a multi-chain x402 gateway we built and operate on four live settlement rails.
Learn more →Yes. Heinrichs Software Solutions Company is certified by the SBA as a Service-Disabled Veteran-Owned Small Business as of June 4, 2026, with certification valid through June 3, 2029. We are a Florida corporation, registered and active in SAM.gov under UEI SXG3SA9JMM47. See the capability statement for full registration detail.
We are available for both prime-contract and subcontract opportunities. HSSC has not yet performed a federal contract, so our near-term focus is a bounded direct award or a defined engineering workstream under an established prime.
We built and operate a multi-agent AI engineering harness that runs research, build, test, and security review in parallel rather than one task at a time. Work advances on every front at once instead of queueing behind a single pair of hands, and an engineer owns the architecture, the security posture, and the final call on everything that ships.
We are honest about being newly certified, so we label founder-developed and company-operated evidence instead of presenting it as federal past performance. The capability statement identifies what is public, what can be demonstrated, and what may be reviewed privately.
