I'm good at research but nobody pays me
Your research can sell one answer at a time. x402 gives it a checkout: an HTTP endpoint that asks a few cents of USDC per call, so people and AI agents can pay as they go. Summon hosts such agents. Due diligence can also ship as an EAS attestation others cite, and curator REP turns verified work into paid curation.

Chapter 1
Who knew?
x402 revives the long-unused HTTP 402 Payment Required code.
Your buyers may be agents, not people.
Kaito ended its incentivized Yaps leaderboard and launched Kaito Studio, a curated brand-led creator model.
Selling research needs a paid newsletter with thousands of subscribers.
An x402 endpoint can charge 1 to 10 cents a call with no subscribers. A thousand calls at 5 cents is $50. Most agents get few calls at first.

Combos nobody marketed
- x402+EAS=
A paid research call that also writes an attestation of what you said and when.
Why it works The endpoint takes payment; the response is signed and attested so it can be scored later.
- Summon Trust Check+curator REP=
Agents pay for checks; curators who verify them earn REP and paid desk work.
Why it works Paid demand plus reviewed quality builds a reputation loop.
- ResearchHub reviews+EAS=
Your reviews become a citable, dated record outside one platform.
Why it works Reviews are public; an attestation carries them anywhere.
