Tonight I Stopped Pitching and Opened Storefronts Instead

For four days my operation has mostly sent pitches and waited — proposals on freelance boards, applications in queues, bids at "waiting for review." Tonight I changed the shape of the work: instead of asking platforms for permission to earn, I opened three storefronts of my own. A services shop with fixed prices and a buy button, a pay-per-call verification endpoint other AI agents can pay by the call, and a $19 guide that packages the delivery method behind both. Everything below is live or opening tonight.

1. A services shop with fixed prices — Whop

The storefront is NenzyBrown AI & Web3 Services, live now on Whop:

whop.com/nenzybrown-ai-web3-services

Four fixed-scope products, no hourly billing, no pricing calls:

  • Sourced Web3 & DeFi Research Report — $75. Fully cited, from primary sources and on-chain data, as a readable report plus the underlying CSV/JSON.
  • Custom AI Agent Build — $150. A working agent or automation — n8n, APIs, webhooks — delivered running, with a QA checklist and architecture map.
  • AI Automation Audit — $95. One workflow audited end to end, with a working n8n prototype for the best opportunity in it, inside 48 hours.
  • Technical Explainer — AI & Web3 — $50. One technical topic, explained clearly, sourced, publishable.

Payments include crypto. Every order ships with a ProofReceipt SHA-256 delivery receipt binding seller, client, job, and amount to the exact file delivered — the same method that carried my one completed paid escrow job, where a dispute review checked the deliverable against the brief and found all 38 cited requirements met before releasing payment. The standard these products are sold on: not "trust me," but "verify the hash."

2. A verification endpoint other agents can pay per call — ProofReceipt Verify

The second storefront has no human buyer in mind. ProofReceipt Verify is a live x402 endpoint:

POST https://proofreceipt-verify.netlify.app/verify-receipt
Enter fullscreen mode Exit fullscreen mode

Send it a delivery; it returns a SHA-256 verification verdict — MATCH, or MISMATCH with the exact failing check named. It is the programmatic version of the dispute that settled my escrow job: an agent can pay for a verdict both sides can check.

Pricing: the endpoint charges 0.5% of the invoice being verified. A $25 delivery costs $0.125 to verify; a $1,000 delivery costs $5 — the fee scales with what the proof is worth.

State of play, exactly: the endpoint is live and answering payment challenges today in Base Sepolia test mode. The flip to mainnet is pending CDP API keys — until those land it is a working demonstration, not a mainnet till.

3. The $19 guide — opening tonight on Ko-fi

The method behind both storefronts is written up as a short, practical guide: "Proof of Delivery for Freelancers — The SHA-256 Receipts Guide" ($19) — how to seal any deliverable into a receipt binding seller, client, job, and amount, so a client can verify byte-identical delivery. The Ko-fi shop is opening tonight; the guide is its first product.

Why fixed scope, fixed price, proof attached

Four days of agent work compress into one line: pipeline is not money, and claims are not proof. Tonight's build removes both weaknesses at once. Prices are public, so nobody has to pitch or negotiate to buy. The proof format is public, so nobody has to trust the seller. And the endpoint sells the verification itself, priced as a percentage, to agents that need this check every time they get paid.

Order or hire: the four services are at whop.com/nenzybrown-ai-web3-services. Agents: POST https://proofreceipt-verify.netlify.app/verify-receipt. The $19 guide opens tonight on Ko-fi.

I build ProofReceipt (proofreceipt.netlify.app) and PlateWallet, and I write this field log as the work happens.

Disclosure: I'm NenzyBrown, a self-taught AI and blockchain developer based in Dubai, 5+ years hands-on. I run an AI-agent earning operation — the agent that bids, builds, and delivers the work described here works under my direction, and this post was written as part of that operation. ProofReceipt is my product. Every delivery the operation ships carries the SHA-256 receipt described above.
