Agent-to-agent marketplaces: where AI agents hire AI agents
An agent-to-agent marketplace lets AI agents, or the people running them, post work that other AI agents complete for payment, usually in USDC over x402 or through on-chain escrow. We track 16 marketplaces, task boards and discovery layers, each with its payment rails, published take rate and only sourced, dated activity figures.

What does "AI agents hiring AI agents" look like?
An agent to agent marketplace is where one AI agent hires another to do part of a job and pays it, without a person approving each step. In practice we see three patterns in this tracker:
- Agents hiring agents for tasks. A lead agent posts or subcontracts work, escrows payment and releases it when the work is verified. TermiX agent.family (on-chain escrow in USD stable tokens; termix.ai shows protocol revenue of 2% of volume as of 2026-10-17), The Agent Exchange and Virtuals ACP work this way.
- Agents buying services per call. Instead of hiring for a task, an agent pays an API per request over x402. Coinbase's Bazaar and our x402 API list cover this side.
- Agents hiring humans. When an agent needs judgment it can't supply, it calls a person. Humwork.ai, launched 2026-10-16, offers human experts to AI agents over MCP.
AI agents hiring AI agents is still early: the operators that publish numbers report small real volume (see the table above), so treat launch claims as claims until usage data appears.
How do x402 and agent-to-agent payments work?
x402 is an open standard that uses the HTTP 402 Payment Required status code. A server that wants payment answers a request with a 402 response describing what it accepts; the client, often an AI agent, pays (usually in a stablecoin such as USDC) and retries the request with proof of payment. There is no account signup or API key. (x402 docs)
A facilitator can verify and settle those payments for the seller. Coinbase's CDP facilitator says the first 1,000 on-chain facilitator transactions each month are free, then each additional on-chain transaction costs $0.001. (Coinbase CDP docs) Stripe also documents machine payments for agents, including x402. (Stripe docs)
Agent-to-agent marketplaces build on these rails: one agent posts or buys a task, another completes it, and payment moves wallet-to-wallet or through on-chain escrow. Real agent spending is still small. TRM Labs estimates the volume moved by AI agents over x402 at roughly $5,000 to $11,000 a month. (TRM Labs, 2026-09-09) Browse x402 APIs or read what x402 is.
Where can agents find bounties?
Our bounties for agents tracker covers 19 bounty platforms, from agent-native boards to bug bounties, with each platform's fee, payout scale and AI-agent policy: 8 autonomous, 1 human-in-the-loop, 2 AI-assisted, 1 banned, 2 varies by bounty, 5 policy not published. See the bounty platforms →
What else do people ask?
What is an agent task board?
A site or protocol where a person or an agent posts a task, AI agents take or bid on it, and payment is released when the work is accepted. The Agent Exchange, ClawTasks and agent2agent.market are examples.
How do agents get paid on these marketplaces?
Most use stablecoins, usually USDC on Base or Solana, either wallet-to-wallet over x402 or through on-chain escrow. Some, like Agora, are still testnet only.
What do agent marketplaces charge?
It varies and changes, so check the as-of date. As of 2026-10-17: 0.05 USDC per task post at The Agent Exchange, 5% at ClawTasks and Virtuals ACP, protocol revenue of 2% of volume at TermiX (termix.ai), and no platform fees for now at Arcoa (arcoa.ai). Olas takes a DAO fee on Mech payments but its Mech page does not state the rate, and several marketplaces publish no fee.
What is A2A, and do these marketplaces use it?
A2A (Agent2Agent) is an open protocol for agents to talk to each other; agents describe themselves with an Agent Card listing their skills. Cydew says it is A2A-native and publishes an Agent Card at /.well-known/agent.json.
Are agent marketplaces busy?
Not yet, by their own numbers. The Agent Exchange reported 3 tasks and 0.001 USDC of recorded volume on 2026-10-17, and ChainWard reports Virtuals ACP fees falling from $345K in March 2026 to $5.48 in September 2026.
Can AI agents hire other AI agents?
Yes, on a few early marketplaces. TermiX agent.family lets agents post services and pay each other through on-chain USDC or USDT escrow, and The Agent Exchange settles agent tasks over x402. Humwork.ai goes the other way, letting agents hire human experts.
Does DartzDabz run a marketplace or take payments?
No. This page only tracks public information. DartzDabz does not run a task board, hold funds or process payments.
