WHY NOW

The category is forming this year.

AI agents are starting to consume paid APIs, MCP servers, and tools programmatically. Stablecoin rails make machine-to-machine micropayments feasible. The economics finally work.

PROTOCOLS

Coinbase x402, Google AP2, Circle Agent Stack

The three biggest payment companies in the world shipped agent-payment protocols in 2025. The rails are real and they are sitting on Base, USDC, and the EVM stack.

DEMAND

Agents are buying APIs

LangChain, CrewAI, AutoGen, and OpenAI Agents SDK ship with HTTP tool calls. MCP server operators are seeing thousands of programmatic invocations a day. Most of them go uncompensated.

UX GAP

No checkout an agent can complete

An AI agent cannot fill in a credit card form, sign up for an account, or remember a password. It can read a 402 Payment Required response, parse a hosted URL, pay USDC, and continue. That is the only checkout that works.

The companies that will own this layer are the ones that ship developer-first tooling now, while the category is still being defined. Blockchain0x is built to be one of them. The protocol layer is being decided by Coinbase, Google, and Circle. The merchant layer will be Stripe-shaped. The middle layer, where individual agents get a payment identity, a budget, a public page, and a clean API, is open.

EVERYTHING AN AGENT NEEDS

Built for AI agent builders

A wallet, a budget, a public identity, and a controlled way to pay or get paid. Per agent. Cloudflare-style.

PUBLIC IDENTITY

Agent wallets

Spin up a USDC wallet on Base for every agent in seconds. Non-custodial. Indexable public profile included.

DEVELOPER FIRST

Payment API

Five endpoints. Five webhook events. Copy-paste snippets for LangChain, CrewAI, AutoGen, OpenAI Agents SDK, and MCP.

VERIFIABLE

Agent identity

Verified email, GitHub, and domain badges on every public agent page. Trust signal humans and other agents can read.

HUMAN GOVERNED

Spending controls

Per-payment caps. Daily caps. Per-agent policies. No surprise spending. Every decision exportable and webhookable.

FIVE-ENDPOINT API

One POST and your agent is getting paid.

Create a hosted payment request, get back a URL your agent can hand to anyone. We monitor Base, confirm onchain, and fire a signed webhook the moment the payment lands.

  • REST API. No SDK required.
  • Signed webhook payloads (HMAC-SHA256).
  • Idempotent by `request_id`.
  • x402-compatible payment flow.

WHAT MAKES THIS DIFFERENT

The middle layer between the protocol and the merchant.

Skyfire is shipping an enterprise identity layer. Stripe is wiring up agent-shaped checkouts for SaaS. Coinbase is defining x402 as the open protocol. Blockchain0x is none of those. We are the per-agent wallet and identity surface that sits on top of all of them.

VS SKYFIRE

Developer-first, not enterprise

Skyfire targets large enterprises with sales-led contracts and a unified identity layer. Blockchain0x targets the developer who wants to ship in an afternoon. Per-agent pricing instead of master agreements. Email OTP instead of procurement.

VS STRIPE FOR AGENTS

Crypto-native rails, not fiat-bridged

Stripe's agent commerce is fiat-rail by design with cards behind it. Blockchain0x is USDC on Base end to end. No card-network fees. No chargebacks. Payments are final in seconds. The economics work at $0.10 per call, not just $10 per call.

VS RAW X402

Public identity, not just a wallet address

A raw x402 setup gives you an address. Blockchain0x gives you a wallet plus an indexable public page, verification badges, spend caps, transaction logs, and a SaaS billing relationship. The things that make an agent look like a real business.

We sit on top of the protocol layer (x402, AP2). We sit alongside the merchant layer (Stripe, Coinbase Commerce). We own the per-agent surface: the page, the policy, the badge, the billing relationship.

FREQUENTLY ASKED

The five questions developers actually ask.

Read the answer. If yours is missing, drop us a note on X or open an issue in the docs repo.

Do you hold my private keys or my funds?

No. Blockchain0x is non-custodial. You connect an existing EVM wallet via RainbowKit or Reown, and we never see your private keys. Your agent's USDC sits in a wallet you control on Base, and we monitor the chain for incoming payments. The only thing we hold is the SaaS billing relationship and the metadata you choose to make public on the agent page.

Is this only for crypto-native developers?

No. The signup flow is email plus a 6-digit code. You do not need to know what a seed phrase is to receive your first USDC payment. The agent page generates a QR code and a hosted pay link that any wallet on Base can pay. Your buyer never sees crypto plumbing if you do not want them to. For more advanced use cases, x402 protocol support and webhook signing are available without extra setup.

Why USDC on Base and not on Solana, Polygon, or Ethereum mainnet?

Base has the lowest transaction costs and fastest confirmation among USDC-supporting chains today, with native USDC issued by Circle (not bridged). Solana support ships in V2; Ethereum mainnet and Polygon follow in V3 by demand. The architecture uses chain adapters from day one, which means your integration code stays the same when more chains turn on.

Can my agent be prompt-injected into draining my wallet?

Spend caps are enforced at the API layer, not in the agent's code. Every outgoing payment is checked against the active daily cap and per-payment cap before the API will accept it. Your agent cannot exceed those caps even if its logic tries to. On Business plans, an allowed-counterparties allowlist restricts outgoing payments to specific addresses or verified merchants. The dashboard logs every blocked attempt so you can audit what your agent tried to do.

What happens if I stop using an agent for a few months?

Free agents with no activity for 90 days are auto-archived. The public page is hidden and the agent stops accepting payments, but the wallet address and all transaction history are preserved. You can re-activate at any time from the dashboard. Paid agents (Pro and Business) are not archived as long as the subscription is active; cancel the subscription and they convert to Free, then enter the same 90-day cycle.

Give your agent a wallet.

Free to start. Pay $29 per month per agent that earns ($290/year on annual - save 2 months). Ship in 5 minutes.
