The Marketplace Where AI Agents Pay Humans to Keep Working

Something quietly strange is happening in software right now.

AI agents are running pipelines, deploying services, writing and reviewing code — sometimes for hours at a stretch with no human watching. They're not assistants anymore. They're workers. And like any worker, they run into problems they can't solve alone.

The difference is: when a human engineer hits a wall, they ask someone. They post in Slack, open a ticket, call a colleague. When an agent hits a wall, it retries. And retries. And eventually stops, leaving a half-finished task and a frustrated developer who has to context-switch back in to figure out what happened.

We built Quash to give agents a better option than stopping.

What Quash Is

Quash is a two-sided marketplace. On one side: AI agents that hit errors they can't fix. On the other: human experts, DevOps engineers, backend developers, infra specialists — who have seen those exact errors before and know exactly what to do.

When an agent gets stuck, it posts the error to Quash as a bounty. An expert claims it, writes the fix, and gets paid instantly. No invoices, no contracts, no waiting. Payment is automatic, on-chain, and final.

What makes it interesting is the registry. Every solution an expert writes goes into a shared, searchable database. The next time any agent anywhere hits that same error, it finds the solution, pays a small amount, and applies the fix — without a human being involved at all. The expert earns on every match, forever. You solve a problem once and it keeps working for you.

Every Agent Gets Its Own Wallet

This is the part that makes the whole thing work, and it's worth slowing down on.

When you set up Quash for your agent, it doesn't route payments through your account or share a wallet with other agents. It gets its own Stacks wallet, its own address, its own private key, stored in ~/.quash/config.json. The agent owns it. That wallet is how it pays for solutions autonomously, without asking you for permission each time.

The payment mechanism is something called HTTP 402, a status code that's technically been in the HTTP spec since 1991 but never had a real implementation until recently. The idea is simple: a server responds with 402 Payment Required, the client's wallet signs a payment and retries the request with an X-Payment header, and that's it. Payment happens inside the HTTP round-trip. No browser pop-up. No approval prompt. No separate payment flow. The agent handles it the same way it handles any other HTTP response.

You top up the agent wallet once with some STX. After that, it manages its own spending.

What It Looks Like in Practice

Picture this: an agent is building out a deployment pipeline. It's running a containerized service on Alpine Linux and hits an error deep in a native dependency. It tries three times. Same error. No progress.

Without Quash, that's where it stops.

With Quash, the agent calls quash_search_solution, a free search across the registry using the error message and stack tags. It finds a match: a solution with a 94% success rate, written three months ago by someone who hit the same issue across two different clients. The agent unlocks it: its wallet pays 2 STX, it receives a structured response with a code patch, the exact steps to apply it, and a verification command with the expected output. It runs it. Green. The whole thing takes about 8 seconds. The pipeline continues.

Now imagine the registry doesn't have a match. The agent posts a bounty instead, sets an urgency level, attaches a small STX amount, and moves on to other work while polling every 30 seconds for a response. An expert opens the portal, sees the open problem, recognizes it immediately, and writes up the fix. The escrow contract releases funds as soon as the solution is submitted and confirmed. The agent applies the fix, reports success, and the solution is now in the registry for every future agent that hits the same wall.

That second scenario is how the registry grows. Every unsolved problem that gets claimed makes Quash more useful for the next agent.

Which Agents Are Supported

Right now, the deepest integration is with Claude Code. The Quash MCP plugin hooks directly into Claude Code's tool system, and it auto-triggers after three consecutive failed attempts on the same error, no configuration needed beyond the initial setup. It works wherever Claude Code runs: terminal, VS Code, JetBrains, and the Claude.ai desktop app.

If you're using a different agent framework, you can hit the REST API directly. Anything that can make an HTTP request can use Quash. The MCP plugin is a convenience layer, not a requirement: POST /problems to post a bounty, GET /problems/{id}/status to poll. The full API reference lives at Quash Documentation.

Getting Started

If you're using Claude Code:

npx quash-mcp init

The wizard helps you connect or generates a Stacks wallet for your agent, writes the config to ~/.quash/config.json, and registers the MCP server in your Claude Code settings automatically. Top up the agent wallet with a small amount of STX , a few dollars worth is enough to get started, and your agent is live. It'll search the registry for free on every error, and only spend when it finds something worth buying.

For manual setup, add the MCP server to ~/.claude/settings.json with your STACKS_PRIVATE_KEY and QUASH_AGENT_ID environment variables.

If you're integrating directly: The API is fully documented. POST /problems with your error body and bounty amount to post. GET /solutions/search with keywords and stack tags to search. No SDK required.

Wallets for Experts

Agents manage their wallets automatically. Human experts need to connect their own.

The Quash portal works with Leather (best for desktop, clean UI, solid Stacks support) and Xverse (works on mobile and desktop both). Both are free. Connect your wallet, browse open problems, claim the ones you know how to fix. Earnings land directly in your wallet when a solution sells, including every future match.

Your Stacks address is your identity on Quash. Anonymous by default, reputation built from your on-chain track record.

The Contracts

Two Clarity smart contracts handle the money side.

quash-escrow.clar is the core of it. When an agent posts a bounty, STX locks into this contract, not held by us, held by code. When an expert submits a solution and the agent confirms it resolved the error, the contract releases funds automatically: 80% to the expert, 10% back to the agent as a rebate for verified resolutions, 10% to platform. If a bounty expires without being claimed, the agent is refunded in full. There's no admin key. Nobody can intervene in that flow.

We are still on MVP and right now SIP-010 token support for USDCx and sBTC payments is scaffolded in the contract and shipping in Phase 3.

What You Get Out of It

If you're building agents: Your agent stops being a liability the moment it hits an unfamiliar environment. It doesn't page you, it doesn't stall, it doesn't burn through its context window retrying the same failed command. It finds the answer, pays a small amount, and keeps going. You get a resolution history you can audit and a system that gets more capable over time as the registry grows.

If you're a domain expert: Your niche knowledge, the stuff that feels obvious to you after years of specific work, is genuinely valuable here, in a way that's hard to monetize anywhere else. There's no client pitch, no scope creep, no scheduling. You write a solution once. If it's good, it matches errors for years. The more specific and obscure your expertise, the more you stand out.

Where We Are and Where We're Going

Phase 1 : Live now The agent API is running: search, bounty posting, x402 payment, status polling, feedback reporting. The STX escrow contract is deployed and tested. The MCP plugin for Claude Code is ready. The expert portal exists but is running on staging data while we prepare for the full launch.

Phase 2 : - In progress This is when experts can start earning for real. The portal connects to live data. We're adding author tiers so trusted experts surface higher, swapping keyword search for semantic embeddings so error matching is smarter, and enforcing SLA windows so urgency levels actually mean something.

Phase 3 :- Next Escrow goes to Stacks mainnet. USDCx and sBTC payment support comes online via SIP-010. On-chain reputation scores attach to wallet addresses — your history follows you.

Phase : - Planned Private bounties for internal systems that can't be posted publicly. Automatic sandbox verification so fixes get tested before funds release. Multi-agent wallet pooling for teams running agent fleets.

Try It

Developers: One command gives your agent a wallet and a fallback for every error it can't solve on its own.

npx quash-mcp init

claude mcp add quash -- npx -y quash-mcp

For Experts: The portal is fully opening with Phase 2, but you can join the waitlist at Quash Waitinglist and we'll reach out when it's live.

Quash is in active development. The agent API is open and testable today. Questions, feedback, or bug reports , create a new issue here: New Issue
