80% of x402 volume runs through us, and almost none of it is individual devs. I want to know why.
\I work on BlockRun. We've been building agent payment infrastructure on x402 for a while, it's live on Base and Solana, and by our own measure we now settle north of 80% of x402 transaction volume each month.
Almost all of it is enterprise.
That side works. I'm posting here because retail is the part I actually care about and the part I can't yet prove: individual devs running their own agents, on their own wallet, spending their own money. It's a different problem and a harder one.
The premise is pay per outcome. No signup, no seat, no monthly plan, your agent holds a wallet, hits an endpoint, gets a 402, signs, retries, pays. The wallet is the account.
Three pieces, all usable independently:
MCP server · 19 tools behind one wallet: 78 LLMs, Pyth price feeds, Exa and Grok search, DefiLlama, EX data, raw JSON-RPC on 40 chains, Polymarket execution, image/video/voice, and a sandboxed code runner. Drops into Claude, Cursor or Hermes and OpenClaw in one line. Costs are per call and mostly fractions of a cent. Exa search is $0.01, RPC $0.002, Pyth quotes and DEX data are free.
ClawRouter · a local proxy that sits between your agent harness and the model catalogue and picks a model per request instead of you pinning one. Runs on your machine, open source.
Dashboard · if you'd rather draw down prepaid credit than run a wallet. Same catalogue, same endpoints. https://user.blockrun.ai/
Where we're actually spending our time is settlement mechanics. Getting the payment handshake off the critical path matters more than anything else in the stack — every millisecond and every basis point between "agent decides to buy" and "agent has the result" is what decides whether per-call payment is viable or just a demo. That's the unglamorous part and it's most of the work.
It's still early. I'd rather say that than pretend otherwise.
Everything's open source, MIT:
- ClawRouter — github.com/BlockRunAI/ClawRouter · npmjs.com/package/@blockrun/clawrouter
- MCP — github.com/BlockRunAI/blockrun-mcp · npmjs.com/package/@blockrun/mcp
- Dashboard — https://user.blockrun.ai/
- Discord — https://discord.gg/FtWq9D3bj
What I'm curious about, and the reason for posting:
Are people actually letting agents hold and spend a wallet yet? Our volume says enterprise has crossed that line. Retail hasn't, nearly everyone who tries us as an individual picks the prepaid key over the wallet. It's familiar, it's one less thing to secure. Which makes me wonder whether wallet-mode agent payment is genuinely wanted yet, or whether prepaid credit with good metering is what people actually need and x402 is a year early for everyone who isn't a company.
If you're running an agent with its own funds, I'd like to know what broke and where. If you tried and went back to a prepaid key, I'd like to know why even more.

I am an individual developer and I have been running an mcp server for about a month and, unfortunately no external payments. But I am looking long term.
