The first time an agent buys a piece of research, a nickel makes sense. The hundredth time, I start thinking about a subscription.
I run AgentToll, where agents can buy research and data one call at a time using x402. I like the model. A buyer can try a service without negotiating a contract or committing to a month of access. But building on a pay-per-call rail has also made me appreciate the other side of the transaction.
Some questions come back every day. The price of asking them should reflect that.
Rail Watch now has a monthly plan, with stablecoin billing powered by Reclack. You can still buy one result for $0.05 in USDC on Base. Or you can subscribe for $9.99 a month and get 300 calls. At the per-call price, those 300 calls would cost $15.
Same research. A different arrangement for the people who come back.
A subscription without the card
I wanted the monthly option to fit the same world as the rest of AgentToll. Our buyers already encounter stablecoins when they use x402. Asking them to leave that world and put a card on file for recurring access felt like an unnecessary detour.
Reclack builds billing around wallets. A customer can subscribe with stablecoins, and a seller can receive recurring payments at a configured address. Reclack also has checkout, invoices, payment links, and a customer portal. Those are familiar pieces of a billing stack, built for a different way to pay.
That distinction is worth sitting with. Stablecoin payments are often presented as a way to move money quickly. A business also needs to know who paid, what they paid for, and whether access should continue next month. Reclack is working on that less glamorous half of the problem, and it's the part that made the integration useful to us.
For Rail Watch, Reclack handles the recurring payment. AgentToll handles access and the research. The monthly subscription is separate from an x402 payment on every call.
Why this research comes back
Rail Watch follows the payment rails being built for agents. It keeps a dated ledger of developments and separates announced integrations from documented settlement.
That separation matters to me. A new integration tells you someone is building. Evidence of settlement tells you something different. Both belong in the record, but they shouldn't be mistaken for each other.
One call is useful when you need a snapshot. If you're following the space over time, the changes between snapshots become part of the work. That's the use case behind the monthly plan.
The meter still matters
I don't think a subscription replaces pay-per-call. A buyer testing a source once shouldn't need a recurring bill. A team checking it repeatedly may prefer a known monthly price.
The monthly plan has a 300-call allowance, not unlimited access to the AgentToll catalog. Calls that fail on our side aren't counted; an interrupted call can use one call of the allowance.
Those details belong in the open. A predictable bill only helps if the buyer understands its limits.
What's next
We're also developing an institutional Research Desk for pilot buyers who want a person following the evidence alongside the structured data. The planned work includes ledger updates, an evidence archive, a weekly brief, and a monthly analyst call.
For teams that want that research connected to their own systems, Integrated Delivery is coming too. The plan is to bring the Desk into your workflow with a dedicated feed, API access, and direct analyst support. Both offerings are in development, so watch for more as they take shape.
For now, Rail Watch is available one call at a time or by the month. I'm glad Reclack gave us a way to add the second option while keeping stablecoins part of the experience.
