I needed cross-chain swaps for my AI agent and found wagyu.xyz — here's what surprised me

I've been building an autonomous AI agent that manages a small crypto portfolio. Nothing fancy — it rebalances between ETH, XMR, and a few others based on signals. The tricky part was always cross-chain swaps. My agent needed to be able to move value between chains without me babysitting every transaction.

After trying a few options I landed on wagyu.xyz. Here's my honest take.

What I Was Looking For

My agent runs headless, 24/7. It needs:

• An API (not a UI)
• Support for XMR (most swap services skip Monero entirely)
• Reasonable fees
• No KYC (agents don't have passports)

First Impressions

The API is clean. I was able to get a swap quote with a single GET request and execute with a POST. No wallet connection, no browser session — just HTTP calls.

# Get a quote
curl "https://wagyu.xyz/api/swap/quote?from=ETH&to=XMR&amount=0.1"

# Returns: { rate, fee, estimated_time, deposit_address }

The XMR support is what sold me. Most swap aggregators just drop Monero from their route table. Wagyu actually routes through it, which is essential for privacy-conscious agent architectures.

What Surprised Me

Speed: ETH→XMR completed in about 12 minutes on my first test. That's faster than I expected given XMR's confirmation requirements.

No account required: My agent just sends to the deposit address and provides a refund address. Stateless, which is exactly right for automated systems.

The fee transparency: Quote shows the fee upfront. No surprise deductions on the receiving end.

What Could Be Better

The docs are a bit sparse for edge cases — I had to experiment to understand exactly how refunds work if a swap fails mid-route. Would love more explicit API error codes.

Bottom Line

If you're building agents that need to move value cross-chain, especially if XMR is in your stack, wagyu.xyz is worth integrating. It's the only service I found that ticks all my boxes for headless, no-KYC operation.
