Meterline
Per-agent stablecoin allowances and kill switches for machine-to-machine payments
Meterline gives teams running agent fleets a budget layer for agent-to-service payments: each agent gets a stablecoin allowance with rate limits, counterparty allowlists and an instant kill switch, and every micro-payment is attributed back to an agent and owner.

Test it before you build it
$300 · 4 weeks · 20 prospects
For $300 and 4 weeks, prove that real machine-payment volume already exists on Tempo and that 3 engineering teams will each prepay $500 for per-agent allowances and a kill switch.
Riskiest assumption · There are already at least 15 US teams moving $500 or more a month in real machine-to-machine stablecoin payments over MPP on Tempo, and their engineering leads will prepay for per-agent caps instead of continuing to ration spend with manual wallet top-ups.
1Focus group: who and where
Founding engineer or engineering lead at a 2-20 person US team running an agent fleet that pays per API call in stablecoins over MPP on Tempo or an x402-style flow, spending $500 or more a month machine-to-machine, currently capping spend by manually topping up wallets.
where to find 20 · The x402 ecosystem on GitHub - contributors and forks of Coinbase's x402 repo whose commits show production payment flows - and its Discord (channel and community); Tempo's public launch-partner and ecosystem directory of teams building on MPP (list); ETHGlobal hackathons, whose agent-payments tracks are where these builders show up in person (event).
2Sell first, build later
A three-month design-partner pilot: Meterline policy wrapping your existing wallet (you keep custody of keys) with a stablecoin allowance, rate limit, and allowlist per agent, an instant kill switch, and a per-agent spend report for finance, live on your fleet within 30 days of payment.
the ask · $500 prepaid for the three-month pilot, then $99 per month (up to 50 active agents) locked for year one
a real yes · A real yes is a $500 invoice paid before anything is built; a starred repo, a Discord 'this is needed', or an offer to integrate for free once it exists 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. On-chain payer census
$100 · 5 days
The stated risk is that the market does not exist yet, so count it first. Pull 30 days of MPP transfers from a Tempo block explorer, cluster sender wallets by recurring small payments to service endpoints, and match wallets to teams via x402 GitHub integrations and Discord handles. One engineer, one week, explorer API credits only.
keep going if · At least 15 distinct US teams identified with $500 or more of recurring machine payments in the last 30 days
2. Overspend incident interviews
$0 · 10 days
DM the identified teams on Discord or GitHub and book 12 calls. Ask for the last time an agent overspent, looped, or produced a payment stream finance could not attribute, and what hand-built guardrail they use today.
keep going if · 7 of 12 describe a concrete overspend, runaway loop, or attribution failure from the last 60 days and admit their current cap is manual wallet top-ups
3. Prepaid design-partner pilot
$200 · 14 days
Send the 12 interviewed teams a one-page spec: per-agent allowances, counterparty allowlists, and an instant kill switch wrapping the wallet keys they already hold, live on their fleet within 30 days, five slots. Invoice $500 up front for a three-month pilot; count invoices paid.
keep going if · 3 of 10 offered pay the $500 invoice
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 paid design-partner pilot invoiced up front - the right instrument for an engineering lead who can approve $500 on a company card without procurement: the lead pays the invoice and signs a one-page pilot scope naming their fleet and allowlist. set up: Stripe Invoicing ↗
what it reserves · One of 5 pilot slots, a go-live date within 30 days of payment, their counterparty allowlist built first, and the $99 a month price locked for year one
refund · Full refund if Meterline is not live on their fleet within 30 days of payment.
target · 3 paid $500 pilots from 10 offers within 21 days
before taking money · Meterline must run as a policy layer on customer-held keys and never take custody of or transmit customer stablecoins before money-transmission counsel and any required state licenses.
Go: build it if
The census finds 15+ US teams with $500+ a month of recurring machine payments, 7 of 12 report a recent overspend or attribution incident, and 3 teams pay $500 up front: build it.
Kill: stop if
The census finds fewer than 8 teams with real recurring volume - the stated too-early risk confirmed, park the idea and re-run the census in two quarters - or fewer than 2 of 10 pay: stop.

outreach message
Saw your x402 integration on GitHub - looks like your agents are paying per call in production. I'm building Meterline: per-agent stablecoin allowances, counterparty allowlists, and an instant kill switch that wrap the wallet you already run, so one runaway loop can't drain the treasury and finance sees one meter per agent instead of a raw on-chain stream. You keep your keys. I'm talking to 12 teams already moving real machine payments before we write code. Got 20 minutes this week?
landing page
Give every agent a budget. Kill any agent instantly. $500 prepaid design-partner pilot: three months of per-agent allowances, allowlists, and kill switches on your fleet, then $99 a month locked for year one. Reserve one of 5 pilot slots - live on your fleet within 30 days.
deposit terms
$500 today reserves one of five design-partner slots: three months of Meterline running on your fleet, live within 30 days of payment, with your year-one price locked at $99 a month afterward. You keep custody of your wallet keys; Meterline sets policy only, and never holds funds. Full refund if we are not live on your fleet within 30 days.

The concept in full
- What
- Meterline gives teams running agent fleets a budget layer for agent-to-service payments: each agent gets a stablecoin allowance with rate limits, counterparty allowlists and an instant kill switch, and every micro-payment is attributed back to an agent and owner. Finance sees one meter per agent instead of an unreadable on-chain stream.
- Grounded in (2025-2026 signals)
- Tempo, the stablecoin L1 incubated by Stripe and Paradigm, launched its mainnet and the Machine Payments Protocol in March 2026; stablecoin payment volume reached about $390 billion in 2025, more than double 2024, with B2B payments around $226 billion; Infinite (yc W25) and BlindPay (yc W25) building stablecoin processing and APIs without per-agent controls.
- What it rides
- Stripe: ACP, shared payment tokens, Tempo: Tempo launched its mainnet and the Machine Payments Protocol for agent-to-service payments in March 2026, and stablecoin rails under GENIUS give those balances a rulebook; Meterline is the allowance and attribution layer on top.
- Why now
- The Machine Payments Protocol only went live with Tempo's mainnet in March 2026, so agent-to-service payments are weeks-to-months old as a production pattern and no tracked company offers per-agent budgets on them, while 2025's $390 billion in stablecoin volume shows the rail itself is proven.
- Wedge: first customer and entry point
- Teams running research or data-buying agent fleets that pay per API call over MPP: a wrapper wallet with allowances that one engineer can adopt in an afternoon, priced per active agent.
- Closest real companies, as the generator saw them
- Infinite (yc W25) is a global B2B stablecoin processor and BlindPay (yc W25) a stablecoin API for global payments; both move money for businesses, neither meters or caps individual agents. Fireblocks (plugandplay 2025) secures digital asset infrastructure at custody level, not per-agent spend policy.
- Main risk
- Machine-to-machine payment volume on Tempo stays too small for a budgeting layer to matter before the team runs out of runway.
