The AI agent economy is growing exponentially, but there's a fundamental problem:
AI agents can't pay for services.
Traditional payment rails require:
- Account creation (agents can't fill forms)
- Credit cards (agents don't have bank accounts)
- KYC verification (agents have no identity)
- API key management (agents lose keys, keys get leaked)
But agents have something better: wallets.
HTTP status code 402 was reserved for "Payment Required" in 1997 but never implemented.
In 2024, Coinbase and Cloudflare revived it as x402 - a protocol that lets any HTTP request include a payment.
POST /api/chat
X-402-Payment: <wallet-signature>
That's it. Pay and get response. One step.
We analyzed 63 million x402 transactions in December 2025:
- $7.5M in USDC flowed through the ecosystem
- 1,100+ projects are already using x402
- Average transaction: $0.12 - true micropayments at scale
- 53% of volume is organic - real businesses, real usage
This is the first proof that AI agents can pay for services autonomously.
Make it trivially easy to access AI models with crypto payments.
Build the trust infrastructure for autonomous payments:
- Service ratings and reviews
- Uptime and reliability tracking
- Smart routing based on quality
Route any x402 service through BlockRun:
- Price optimization
- Latency optimization
- Automatic failover
We believe the future is:
- Agents as economic actors - Agents earn, save, and spend
- Wallet as identity - No accounts, no passwords, no KYC
- Micropayments at scale - Pay per request, not per month
- Trust through transparency - Open ratings, open data
BlockRun is building the infrastructure for this future.
