FAQ's
How does Beep work?
Beep connects three layers:
Beep Pay — zero-fee stablecoin checkout with instant settlement
a402 protocol — HTTP-based agent-to-agent payment standard
Agentic Yield — on-chain USDC yield engine that funds gas and rewards users
Agents use session keys to transact directly with vaults, and every transaction generates a verifiable on-chain receipt.
What is a402 in Beep?
a402 is Beep’s implementation of Coinbase’s x402 protocol, which enables HTTP-native, on-chain payments. It allows AI agents, APIs, and apps to pay or get paid as part of a normal web request — using stablecoins like USDC. Each payment creates a cryptographic receipt, verified by Beep’s facilitator.
What is x402 payment protocol?
x402 is a new payment standard introduced by Coinbase that embeds payments directly into the web using the HTTP 402 status code (“Payment Required”). Beep extends x402 into a402, enabling machine-to-machine commerce — so AI agents can pay, verify, and settle autonomously.
What makes Beep Pay different from Stripe or PayPal?
Beep Pay is designed for AI agents and APIs, not humans. It supports:
Instant USDC settlement
Zero-fee transactions (gas is sponsored)
No chargebacks or intermediaries
On-chain verification via cryptographic receipts Unlike Stripe or PayPal, Beep never holds your funds — everything settles on-chain.
What is Agentic Yield in Beep?
Agentic Yield is Beep’s autonomous yield engine that compounds USDC across SUI DeFi protocols like Scallop, Bluefin, and Suilend. It funds gas sponsorships and provides passive yield to merchants, agents, and facilitator pools.
How does Beep offer zero-fee payments?
Beep uses a yield-share model: part of the passive yield from idle USDC balances funds network gas and sponsorship pools. Merchants receive the full payment amount, and agents transact without paying gas — effectively zero-fee settlement.
What is a cryptographic receipt in Beep?
A cryptographic receipt is a signed proof of payment issued by Beep’s facilitator. It contains the payer, merchant, amount, and chain details, and is verifiable on-chain. Receipts ensure every transaction is provable, auditable, and machine-readable.
Can AI agents pay each other with Beep?
Yes. Beep is built for agent-to-agent (A2A) payments. Agents can pay other agents, APIs, or merchants using USDC — instantly and programmatically — via the a402 protocol. Each transfer is verified and recorded on-chain.
Does Beep require a crypto wallet?
No. Beep supports walletless sessions — temporary vaults for AI agents or users without traditional wallets. These sessions hold limited balances, expire automatically, and remain non-custodial.
Is Beep safe to use?
Yes. All funds stay in user-controlled smart vaults. Beep facilitators can verify transactions but cannot move or hold funds. Receipts are signed and stored on-chain for full transparency and auditability.
Which blockchains does Beep run on?
Beep currently operates on:
SUI — primary deployment (sub-second finality, native gas sponsorship)
How does Beep integrate with DeFi protocols?
Beep’s Agentic Yield layer connects to DeFi protocols on SUI such as Suilend, Scallop, Bluefin, and Momentum. Agents automatically allocate idle USDC into these protocols to earn yield or offset payment gas costs.
Can developers integrate Beep into their apps?
Yes. Developers can integrate Beep via:
Beep SDK → for programmatic
pay()andverify()Checkout Widget → for instant USDC payments on web
a402 APIs → for HTTP 402-based agentic transactions
The SDK supports both client-side (JS/TS) and server-side integrations.
How fast are Beep transactions?
Beep payments on SUI finalize in <1 second, with deterministic finality. Base and Solana networks confirm within 1–2 seconds depending on load.
What industries use Beep?
Beep is built for:
AI & agentic ecosystems (autonomous tools, model APIs)
DeFi & fintech apps (yield automation, treasury flows)
Digital commerce (pay-per-content, pay-per-API)
Gaming & metaverse platforms (instant microtransactions)
What’s the vision behind Beep?
Beep is building the financial stack for the agentic economy — where software agents can pay, earn, and manage value autonomously. The mission: make payments as fast, verifiable, and programmable as code.
Who is building Beep?
Beep is built by a team of repeat AI and fintech founders, with support from the SUI ecosystem and strategic partners in Web3 infrastructure.
What is the a402 protocol? a402 is an open protocol that uses the standard HTTP‑402 “Payment Required” loop to enable per‑call payments for tools, APIs, and agents. Pattern: request → 402 challenge → pay → verify/release.
How does a402 differ from L402 or x402? • L402 focuses on Lightning + macaroons; strong for BTC but requires Lightning infra. • x402 emphasizes EVM payments; identity is out‑of‑band. • a402 includes built‑in identity/authorization, supports off‑chain session channels for bursty micro‑flows, and is designed for agent/AI protocols (MCP, a2a, AP2).
What makes Beep different from legacy processors? Sub‑second settlement on Sui, near‑zero fees, per‑call/per‑token granularity, real‑time yield streaming, and an AI‑native UX ("talk to money").
How do you make money if fees are $0? We share yield generated on payment balances and offer analytics/enterprise features. Merchants avoid traditional card/interchange costs.
What does the Agentic Treasury do? Capture upto 10% APY DeFi yields 24/7 with autonomous financial agents, It’s a non‑custodial system where autonomous agents scan, score, allocate, and auto‑compound across supported Sui protocols, with gas‑smart execution and policy guardrails.
Is this compliant? Beep provides audit‑ready receipts and verification APIs. Authorization policies are programmable. Yield and rewards vary by jurisdiction; availability may be limited.
What’s the latency and reliability profile? Targets sub‑second verification with standardized errors and idempotent retries. Production metrics will be shared post‑beta.
Who is this for? Sui developers (apps/games), AI developers (per‑tool monetization), platform operators (agent‑to‑agent micro‑settlement), and individuals or teams managing stablecoin treasuries.
What’s coming next? Rewards for early treasury adopters, wallet partnerships, and DeFi partner promos; more SDKs and MCP/a2a templates.
