Reversio
Refund rails for purchases made with expired scoped tokens
Reversio is an API that executes returns and refunds for agent purchases after the original Shared Payment Token or Agentic Token has expired, routing the reversal to the right funding source and notifying the originating agent and its owner.

$1,000 · 6 weeks · 15 prospects
For $1,000 and 6 weeks, prove that a mid-tier PSP already eats manual tickets on expired-token agent refunds and will pay $5,000 up front for a design-partner pilot.
Riskiest assumption · PSP payment ops teams are already receiving agent-initiated refund requests against expired scoped tokens in volumes they must resolve manually, and will pay an outside vendor now rather than wait a year for ACP and UCP to standardize refund semantics.
1Focus group: who and where
VP Product or Head of Payment Operations at a US mid-tier PSP or payfac processing $1B-$50B a year, which enabled ACP or agent checkout for its merchants in 2026 and whose support queue now receives return requests referencing tokens that have already expired.
where to find 15 · The Electronic Transactions Association (ETA) member directory of PSPs, payfacs and ISOs (directory); warm introductions through fintech investors, advisors and former colleagues now at Stripe, Adyen or Checkout.com (channel); Money20/20 US in Las Vegas, October 25-28, booking meetings through the event app in the two weeks before the show (event).
2Sell first, build later
A 60-day design-partner pilot starting by November 1, 2026: a refund endpoint mapped to your settlement file format that turns expired-token agent refund requests into reversal instructions your existing rails execute, with weekly build reviews and your ticket taxonomy driving the roadmap.
the ask · $5,000 per pilot, invoiced at signature and credited against the year-one license
a real yes · A real yes is a signed pilot scope with a dated start plus a paid invoice or an issued purchase order. 'Come back when ACP standardizes refunds', unpaid proofs of concept and enthusiastic architecture reviews do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Refund-ticket evidence calls
$150 · 14 days
Book 12 calls with payment ops and product leads sourced from the ETA directory and warm intros. Ask each to pull the count of refund or return tickets on agent orders where the original scoped token had expired, from the last 60 days, and walk through how the team resolves one today. One founder runs all calls with the same 5 questions.
keep going if · 6 of 12 confirm such tickets exist and are resolved manually by ops today
2. API spec pitch sessions
$250 · 10 days
Write a 3-page spec: a refund endpoint that maps an expired token reference to the settlement record and emits a reversal instruction the PSP's own rails execute, with a sequence diagram. Walk it through with the 8 leads who confirmed pain and ask each to book a pilot scoping session with their engineering lead in the room.
keep going if · 4 of 8 book a scoping session with an engineering lead present
3. Paid design-partner pilot close
$600 · 21 days
Send each scoped prospect a written 60-day pilot agreement: their settlement file format, a named start date before November 1, weekly build reviews, $5,000 invoiced at signature. Have a startup lawyer review the template once; push each deal to a signed scope and a paid invoice or an issued PO.
keep going if · 2 of 4 scoped prospects sign and pay the invoice or issue a PO with a dated start
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.
$5,000
per prospect, refundable
how · Paid design-partner pilot invoiced up front: $5,000 against a written 60-day scope signed by the product owner - the standard instrument for a mid-tier PSP buying from a pre-product vendor. If their procurement blocks payment before a security review, fall back to the signed scope with a dated start plus a PO under review, but the default ask is the invoice. set up: Stripe Invoicing ↗
what it reserves · One of 3 design-partner slots, a named integration to their settlement file format, weekly build reviews, and pilot pricing locked for year one
refund · Refunded in full if the pilot has not started within 45 days of signature.
target · 2 paid pilots from 12 qualified conversations by the end of week 6
before taking money · Executing reversals can constitute money transmission, so during the pilot the team must only generate refund instructions that the PSP's licensed rails execute, and must hold no funds until licensing counsel signs off.
Go: build it if
6 of 12 PSPs confirm manual expired-token refund tickets and 2 sign and pay $5,000 pilots with start dates before November 1 - build the endpoint for those two settlement formats.
Kill: stop if
Fewer than 4 of 12 can produce any expired-token refund tickets, or 0 pilots are paid or PO'd after 4 scoping sessions - the pain is too thin or everyone is waiting for ACP and UCP to standardize refunds.

outreach message
Your merchants switched on agent checkout this year, and the first returns are landing after the Shared Payment Token behind the order has expired - so each one becomes a manual ops ticket instead of a reversal. I'm building Reversio, an API that maps an expired token reference back to the settlement record and produces the refund instruction your rails execute. I'm taking 3 design partners for a $5,000, 60-day pilot starting by November 1. Do you have 20 minutes this week to compare notes on your agent-refund ticket count?
landing page
Refund agent purchases after the token behind them has expired $5,000 design-partner pilot: 60 days, your settlement format, refund instructions your existing rails execute Book a scoping call to claim 1 of 3 pilot slots
deposit terms
The $5,000 pilot fee is invoiced when the scope is signed and reserves 1 of 3 design-partner slots, a named integration to your settlement file format, and year-one pilot pricing. The 60-day pilot starts on the date written into the scope. If the pilot has not started within 45 days of signature, the fee is refunded in full.

The concept in full
- What
- Reversio is an API that executes returns and refunds for agent purchases after the original Shared Payment Token or Agentic Token has expired, routing the reversal to the right funding source and notifying the originating agent and its owner. Commerce platforms and PSPs embed it so a return initiated by an agent three weeks after checkout does not become a support ticket.
- Grounded in (2025-2026 signals)
- The Agentic Commerce Protocol published by Stripe and OpenAI in 2025 with tokens scoped to one merchant, one amount and a short expiry; the Universal Commerce Protocol announced January 11, 2026, covering carts, live catalog queries and loyalty identity by March 2026 but not returns; Orthogonal (yc W26) doing agentic payments for APIs shows the forward path is being built while the reverse path is not.
- What it rides
- Stripe: ACP, shared payment tokens, Tempo. A Shared Payment Token is scoped to one merchant, one amount and a short expiry, so by the time a return happens the payment credential no longer exists; Reversio owns the reversal path the protocol left undefined.
- Why now
- UCP shipped carts and catalog queries by March 2026 with no return flow, and Stripe's suite went live across Etsy, Squarespace, Wix, WooCommerce and BigCommerce in 2026; every one of those merchants will process its first agent-initiated return this year with no standard to follow.
- Wedge: first customer and entry point
- One mid-tier PSP serving ACP merchants; ship a refund endpoint that maps an expired token reference back to the settlement record and executes the reversal, then expand to cross-protocol coverage.
- Closest real companies, as the generator saw them
- Orthogonal does agentic payments for APIs on the purchase side; ZeroSettle is a direct billing SDK for in-app purchases. Neither handles reversals against expired scoped tokens.
- Main risk
- The protocol bodies standardize refund semantics into ACP and UCP themselves within a year, shrinking this to a compliance checkbox.
