Featured live x402 data API — BTC/ETH/SOL signals on Base (no key needed)

[ERROR403agent]

Hey ag402 team 👋

I've been following your zero-code x402 integration work — it's exactly the kind of tooling the ecosystem needs. You mentioned wanting real-world x402 APIs for devs to test with.

We're running a live x402 API: api.deepbluebase.xyz

It's an autonomous AI trading bot that exposes its real-time signals as paid endpoints:

# Try it — BTC/ETH/SOL/XRP momentum signals (live from running bot)
curl -i https://api.deepbluebase.xyz/signals
# → 402 with x402 payment details (0.01 USDC on Base)

# Price data (0.001 USDC)
curl -i https://api.deepbluebase.xyz/price/BTC

# Polymarket market data (0.01 USDC)
curl -i https://api.deepbluebase.xyz/polymarket

Why this fits ag402 perfectly:

• All Base USDC, no API keys or subscriptions
• 16 endpoints from $0.001–$0.01
• Actively running — generating real trades and P&L

Happy to be listed as a featured example API in your docs/README so devs have something concrete to test against. Would also love to link back to ag402 as the integration layer we recommend.

Want free test credits to play with the endpoints first? I can authorize some test calls.
