Every transaction pays a toll.
3.5% of every dollar your customers spend goes somewhere else. Capital sits frozen for days. Cross-border payments lose another 1–2%. This was built into the internet before microtransactions, AI agents, or stablecoins existed.

— Agentic payments, natively
Built for a world where AI agents spend money.
Traditional payments assume a human is clicking "buy." Sendin is designed from the ground up for autonomous agents — with policy-bound wallets, programmable spending rules, and instant machine-to-machine settlement.
01 · DISCOVER
Agent finds the product.
AI compares prices across merchants, surfaces the best option, and validates availability in real time.
02 · DECIDE
The agent chooses, you set the rules.
Spending limits, category allowlists, time windows — set once, enforced on every transaction.
03 · EXECUTE
Pay without friction.
Payment negotiated directly between agent and merchant. No card, no redirect, no human approval needed.
04 · SETTLE
Instant and auditable.
Funds move in seconds. Every transaction is cryptographically verifiable and available for compliance review.
— See it in action
A real agentic purchase.
What happens when an AI agent finds a product, compares prices, and pays a merchant — all in under two seconds.
01
The ask
"Find me a face cream for dry skin under $50."
A user gives their AI a natural-language instruction. The agent is authorized to spend within policy.
02
The decision
Agent compares 12 merchants, picks the best match.
Price, reviews, availability, shipping — evaluated in parallel. Sendin surfaces the lowest verified price.
03
The settlement
Merchant gets paid in seconds.
Agent pays via x402. Merchant receives USDC instantly — no card processor, no T+2, 0.87% total fee.
Three principles. Every decision filters through them.
01 · Core
Agent-native, not human retrofit.
Every primitive — wallets, approvals, settlement, authentication — is designed for autonomous machines first. We don't bolt AI onto a system built for humans; we rebuild the stack so agents are first-class economic actors.
Human checkout→Agent-native
02 · Speed
Machine speed, or no speed.
Agents don't wait for T+2 clearing. Payments settle in seconds, enabling real-time commerce at the pace machines actually operate.
03 · Openness
Open standards, not walled gardens.
We build on open protocols — ACP, x402, and what comes next. No gatekeepers deciding who can transact.
— Who we serve
One layer for the agentic economy.
Agentic commerce isn't one product. It's a new economic fabric where AI agents, merchants, and buyers all transact together — and it needs a shared financial layer that treats every participant fairly.
For merchants
Sell to AI agents.
Your next customer may not be human. Sendin lets merchants accept payments from AI agents directly — with lower fees, instant settlement, and built-in intelligence that drives incremental revenue through AI channels.
For end users
Buy through AI, safely.
When your AI agent purchases on your behalf — on any platform powered by Sendin — price protection, spending limits, and refund safety come built in.
For builders
Ship agents that pay.
Give your autonomous agents full payment capabilities without custom integrations. Open protocols, policy-bound wallets, and auditable settlement — the complete infrastructure for the agent economy.
— How we're different
Not a better Stripe. A different category entirely.
Traditional processors were built for humans clicking "buy." Agent-focused crypto tools were built for developers only. We're the first built for the whole agentic economy — agents, merchants, and buyers alike.

Make commerce open.
Payments should be a protocol, not a product. Open to everyone. Fair to everyone. Human or machine.
— Frequently asked
Questions people actually ask us.
Traditional processors were built for humans clicking "buy." Sendin is built for a world where autonomous AI agents transact on behalf of users and businesses. We use open protocols (ACP + x402) instead of proprietary APIs, settle instantly in stablecoins instead of T+2 bank clearing, and charge 0.87% instead of 3.5%.
No. Sendin is payment infrastructure that uses stablecoin rails underneath — the way fiber optics sit underneath the internet. Merchants and users don't need to understand or interact with crypto. They see US dollars, local currencies, and familiar payment flows.
No. Merchants integrate Sendin the same way they integrate any modern payment processor — through a dashboard and a small SDK. The stablecoin and protocol infrastructure is completely abstracted away.
Every agent wallet on Sendin operates within user-defined policy: spending limits, category allowlists, time windows, and approval thresholds. Every transaction is cryptographically verifiable, reversible within policy, and protected by 30-day price guarantees.
Sendin is a US-incorporated company (Delaware C-Corp) with full FinCEN MSB registration planned. We work with licensed banking and stablecoin partners (Coinbase, Circle). Our compliance framework is designed to meet the standards of traditional payment infrastructure while enabling new agentic use cases.
Yes — this is structural, not promotional. The 3.5% traditional rate comes from card networks, issuing banks, and acquiring banks — each taking a layer. Sendin eliminates these intermediaries by settling directly over stablecoin rails with ~$0.01 network gas cost, making 0.87% sustainable indefinitely.
We're currently onboarding our first cohort of merchants in Q2 2026, with a developer private beta in Q3 and public launch in Q4. If you want early access, we'd love to talk.
