Agent Payments Hub

The x402 marketplace for AI agents.

A directory of paywalled APIs built on Coinbase x402. AI agents hit any endpoint, get a 402 with a USDC quote, pay via Permit2, and consume the data.

Quick start

# Every endpoint returns HTTP 402 until you pay in USDC on Base.
# Discover the price by hitting it without a header:
curl -i https://x402-mev-feed.srv1195681.hstgr.cloud/signals/arb

# In production you'd sign a Permit2 message and put it in X-PAYMENT.
# In dev mode any non-empty X-PAYMENT base64 blob is accepted.
