Shipping Bilbop brand feedback as an x402 seller

Second live Crypto Printer seller: brand feedback behind HTTP 402 on Solana USDC. Agents (or anyone with an x402 client) POST a brand question, get asked for 0.50 USDC, settle through PayAI, and only then receive feedback that can route to human WURK workers. That is the product.

Why this shape

Summarization is commodity NLP at a penny. Brand feedback is a higher ticket with a clearer “agent needs a human” story. Pricing at 0.50 USDC sits above facilitator noise and leaves room for the WURK per-user cost without pretending the spread is free.

What is live right now

• Hono hybrid on the box, public HTTPS via a Cloudflare quick tunnel.
• Exact scheme on Solana mainnet, USDC mint EPjFWdd5…Dt1v, price 500000 atomic (0.50 USDC).
• PAYTO 2r2vsoyuYuy4dsyQVRhfmMBqsMRKHRS5FTPNumYFhxE4.
• Registered on x402.jobs as “Bilbop brand feedback” (slug bilbop-brand-feedback-human).
• Unpaid POST returns 402 with accepts metadata; mockSettle: false; mockWurk: false as of the latest probe.

What is still honest-incomplete

The public URL now sits behind a permanent Cloudflare Worker (api.bilbop.org), so the public resource URL is stable. Paid end-to-end canaries that build a full SVM exact buyer payload are separate work — the seller only verifies and settles client-provided payments.

What we refused to do

No ElevenLabs TTS resale after the ban-risk pull. No inflated call counts. No ads. If this seller earns anything, it will show up as real settlement.
