Test it before you build it
$500 · 3 weeks · 25 prospects
Prove that agent builders adding stablecoin payments will prepay $500 for per-screen sanctions checks, for $500 in 3 weeks.
Riskiest assumption · Founders of agent startups adding stablecoin payments believe sanctions screening is their own launch-blocking obligation, not their PSP's, and will pay per screen for it now rather than wait for an incumbent vendor's low-latency tier.
1Focus group: who and where
The founder or founding engineer at a 2-15 person agent infrastructure startup from the 2025-2026 cohorts that is wiring pay-per-call stablecoin payments into its product this quarter and plans to launch with live money moving before year end.
where to find 25 · The YC Startup Directory filtered to 2025-2026 batches tagged AI agents, cross-checked for payments features in their launch posts; the payments channels of the Coinbase Developer Platform Discord, where pay-per-call builders ask integration questions; AI Tinkerers meetups in San Francisco and New York; r/AI_Agents threads on monetizing agents.
2Sell first, build later
Founding-cohort access to the inline screening API: an integration slot in October 2026, a drop-in check before every Machine Payments Protocol call with pre-screened counterparty sets per agent, hands-on integration help from the founders, and the founding per-screen rate locked for 12 months.
the ask · $0.002 per screen for founding customers, locked 12 months; sold as a $500 prepaid credit pack; free tier for prelaunch sandbox traffic
a real yes · A real yes is $500 charged to a company card for prepaid credits. Sandbox key requests, GitHub stars, 'we would integrate this' and free-tier signups are interest signals, not yeses.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Liability ownership interviews
$100 · 10 days
DM 25 builders from the YC directory and the Coinbase Developer Discord and take 20 calls of 15 minutes. Ask three questions: do you screen counterparty wallets before an agent pays, whose obligation do you believe it is if an agent pays a sanctioned address, and what happens to your launch date if you have to build screening yourself. Log every answer verbatim.
keep going if · 10 of 20 say screening is their own obligation, they have nothing in place, and it threatens their launch
2. Docs-first pricing page
$200 · 10 days
Publish a quickstart-style docs page: the inline check before each Machine Payments Protocol call, pre-screened counterparty sets per agent, sub-10ms latency target, $0.002 per screen with a free prelaunch tier, and a 'request a sandbox key' form. Share it in the Discord payments channels and demo it at one AI Tinkerers night; do not post it as a launch anywhere.
keep going if · 10 of the 40 builders who open the docs request a sandbox key with a real project named
3. Prepaid founding credits
$200 · 10 days
Offer every interviewed builder and sandbox-key requester a $500 prepaid credit pack at the founding rate via a card checkout link on the docs page. A payment link fits here because the buyer is a developer paying a small amount self-serve by card, with no procurement step. Founder follows up personally on every checkout started but not finished.
keep going if · 5 of 25 prospects prepay the $500 pack
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$500
per prospect, refundable
how · A $500 prepaid credit pack bought by card through the checkout link on the docs page, chosen because this buyer is a self-serve developer with a company card and no procurement process; the founder emails a one-paragraph credit agreement receipt after each purchase. set up: Stripe Checkout ↗
what it reserves · A slot in the October 2026 founding integration cohort, the $0.002 per-screen rate locked for 12 months, and founder-led help wiring the check into their payment loop
refund · Refundable in full any time before their first production screen, and refunded automatically if the sandbox API is not live by November 1, 2026.
target · 5 prepaid packs from 25 prospects within 21 days
before taking money · Do not clear any live payment during the test - a wrong 'clear' creates OFAC exposure for the customer - so restrict everything to sandbox traffic until sanctions-list licensing and counsel review are in place.
Go: build it if
10 of 20 interviewed builders own the obligation and have no solution, and 5 of 25 prepay $500 - build the API for the October cohort.
Kill: stop if
Fewer than 5 of 20 see screening as their problem rather than their PSP's, or fewer than 2 prepay after 20 offers - the buyer expects the rail or an incumbent to cover this, and the stated risk is real.

outreach message
Saw you are wiring pay-per-call payments into your agent product. Once real money moves, every counterparty wallet is a sanctions question, and batch screening built for daily wires cannot sit in a loop that fires several times a minute. I am building an inline screening API: pre-screened counterparty sets per agent, sub-10ms checks, $0.002 per screen for the founding cohort, locked for a year, with hands-on integration help. Up for a 20-minute call this week? I will walk you through the docs and latency numbers.
landing page
Sanctions screening that keeps up with your agent's payment loop $500 in prepaid credits buys the founding rate of $0.002 per screen, locked for 12 months, plus an October integration slot with founder support Prepay $500 - fully refundable until your first production screen
deposit terms
Your $500 buys prepaid screening credits at the founding rate of $0.002 per screen, locked for 12 months, and reserves a slot in the October 2026 founding integration cohort with direct founder support. It is refundable in full any time before your first production screen. If the sandbox API is not live by November 1, 2026, we refund automatically.

The concept in full
- What
- An inline screening API that clears counterparties in milliseconds so agents paying per call over stablecoin rails never touch a sanctioned address. It maintains pre-screened counterparty sets per agent so thousands of sub-dollar transfers do not each trigger a full batch check. Sold to agent builders and the platforms hosting them.
- Grounded in (2025-2026 signals)
- Tempo's Machine Payments Protocol launched March 2026; stablecoin payments hit about $390 billion in 2025; MouseCat (yc W26, 'AI to fight financial crime') and Socratix AI (yc S25) show funded demand for financial-crime tooling, but both target human case work; YC's Fall 2026 RFS 'AI-Native Compliance Infrastructure'.
- What it rides
- Stripe: ACP, shared payment tokens, Tempo, specifically the Machine Payments Protocol for agent-to-service payments; screening has to sit inside that payment path, not in a nightly batch.
- Why now
- Agent-to-service payments only got a protocol in March 2026, and existing screening stacks were built for daily wire batches; nobody screening at that cadence can sit in a payment loop that fires many times per minute.
- Wedge: first customer and entry point
- Agent infrastructure startups from the 2025-2026 cohorts that are adding payments: a drop-in check before every Machine Payments Protocol call, priced per screen, with a free tier for prelaunch teams.
- Closest real companies, as the generator saw them
- MouseCat and Socratix AI build tooling for bank fraud and compliance teams working cases; Sievewire is an inline API in the machine-payment path, not a case-management product.
- Main risk
- Incumbent screening vendors add a low-latency tier and win on sanctions-list coverage that a small team cannot match.
