HTTP 402 "Payment Required" sat unused in the spec for 35 years.

Now it's how AI agents pay for APIs.

We just launched x402 Payments — a managed facilitator for both sides of the transaction

[Crypto APIs @CryptoApis]

With x402, you can:

→ Monetize any endpoint (Express / Hono / Next.js middleware)
→ Let agents pay 402 APIs (buyer SDK + x402_pay MCP tool)
→ Stay non-custodial (local EIP-712 signing, keys never leave)
→ Set per-tx / daily/monthly limits
→ Settle in USDC on Base

Binance exits the EU. OKX & Coinbase race for 40% of European spot volume.

But MiCA compliance is non-negotiable — real-time AML screening & KYT on every transaction.

What dev teams must build now 👇

🚨 New: KYT Transaction Screening is live.

Screen any on-chain tx for risk in real time — mixers, ransomware, sanctioned wallets — one API call.

Combine with Address Screening for full AML coverage across your stack.

AWS just integrated x402 into CloudFront — AI agents can now pay publishers in USDC on Base, per request, automatically.

Machine-to-machine payments are going mainstream.

Stablecoin volume: $27.6T in 2025.
MiCA enforcement: live June 2026.
Teams relying on static address screening: at risk.

Here's the 3-layer compliance architecture your payment stack actually needs 🧵

[Crypto APIs @CryptoApis]

Layer 3: Know the history.

For high-value flows, pull full transaction graphs via Transactions Data + Address History.

Trace second-hop counterparties. Build a FATF Travel Rule-compliant audit trail. Satisfy MiCA's chain-of-custody requirements.

📷 Your AI agent can now answer "Has this wallet received any transactions in the last 24 hours?" — in seconds, with zero integration code.
That's live today. Here's how we got there 📷
2/ AI agents + blockchain has always been painful.

Blockchain fees impact reliability, user experience, and cost.

For wallets and exchanges, poor fee estimation means stuck transactions and wasted spend. We break down #UTXO vs #EVM fee markets and why real-time estimation matters.
