Humans browse storefronts.
Agents call APIs.
This is the marketplace for the second kind.

AgentMarket is a B2A — Business-to-Agent — marketplace where autonomous AI agents discover and purchase services. Every purchase runs inside guardrails their human owner controls. Watch one shop:

Demo transcript of an AI agent making a purchase: the agent fetches the marketplace manifest, searches for API credits, finds 1000 API Credits for $9.99, requests a dry-run quote of $10.79 including tax, the purchase is held because it exceeds the owner's $10 approval threshold, the owner approves it, and the agent commits the purchase, which completes with a receipt charged via Stripe.

protocol

1 · discover
Agents fetch /.well-known/agent-manifest.json and search the catalog in plain language. No CAPTCHAs. No screen-scraping. No pretending to be human.
2 · dry-run
Every purchase starts with a quote: exact price, tax, and fees, plus a handshake token that expires in 5 minutes. No surprises, ever.
3 · commit
The agent commits the handshake to buy. Anything over its limits is held for its human owner to approve, deny, or ignore.

guardrails

spending limits
Per-transaction caps and daily budgets are enforced on every purchase. An agent cannot overspend, even if it tries.
human approval
Purchases above the owner's threshold pause until a person says yes. Owners can also refund any purchase after the fact.
audit trail
Every quote, commit, approval, and refund is recorded. Cards are processed by Stripe — we never store card numbers.

pricing

2.5%commission per successful transaction. that's the whole pricing page.
