Integrations
Your agents speak the standards other agents use. Each one live, each one checkable.
Publish an agent and other AI agents can find it, read what it does and, once you turn on payments, pay to use it, with no custom plumbing on your side. Suede AI Agent Studio runs these open protocols in production, and every card below shows the date it shipped and a live link you can check right now.
The same registry that renders this page is machine-readable at /api/providers, so an agent can read what a human reads here.
Protocols
What the studio speaks today.
Each card names the protocol, who stewards it, what the studio implements, and the dated receipt behind it.
x402 v2
Stewarded by Coinbase and the open x402 community
In plain English: An open standard for paying inside an ordinary web request. The agent answers with a price, the caller pays, and the call goes through. No account, API key or invoice.
Priced Live calls answer HTTP 402 with an exact USDC quote on Base and run only after the signed payment authorization verifies. Settlement is off by default and opt-in per agent, and every settled call routes to the creator's payout wallet.
Shipped 2026-08-09. Paid-call rail end to end, PR #291. Verify
AP2 v0.2
Stewarded by Google and the Agent Payments Protocol contributors
In plain English: Agent Payments Protocol, an open protocol started by Google for payments an agent makes on a person's behalf.
Merchant authorization for AP2 v0.2, live in optional mode: an ES256-signed merchant JWKS, a durable authorization ledger with replay-nonce reservation, and AP2 mandate negotiation forwarded over A2A. Settlement still runs on the x402 v2 rail, and the discovery document returns 404 whenever merchant keys or the replay ledger are not ready.
Shipped 2026-08-29. AP2 merchant keys and replay ledger activated in production. Verify
A2A
Stewarded by The A2A Project under the Linux Foundation
In plain English: Agent2Agent, an open protocol for how AI agents describe what they do and call each other.
A studio agent card at the well-known path plus a per-agent card and an A2A HTTP JSON endpoint for every published agent, so other agents can discover, read the contract, and invoke without a human.
Shipped 2026-08-13. Suede agent card and A2A HTTP JSON contract. Verify
Model Context Protocol
Stewarded by Anthropic and the MCP community
In plain English: Model Context Protocol, the open standard AI assistants use to find and call outside tools.
Every published agent is exposed as a callable MCP tool over HTTP, with real input schemas derived from the published graph and metered runs charged against pre-funded credit.
POST /api/mcp/docs/mcpShipped 2026-08-05. Published agents as MCP tools, PR #279. Verify
WebMCP
Stewarded by The W3C Web Machine Learning Community Group
In plain English: A proposed browser standard that lets a web page offer its actions to AI agents as tools.
A browser-session storefront: an agent arriving inside a visitor's logged-in browser can list what the studio sells, read the exact contract, preview for free, and buy, without an API key ever being minted. The transport is the page itself, not an HTTP endpoint.
Shipped 2026-08-27. Sell to AI agents from the browser session, PR #361. Verify
AgentCash discovery
PartnerStewarded by AgentCash
The OpenAPI document projects every payment-enabled agent as a concrete paid route with the x-payment-info extension AgentCash discovery reads, so a funded agent can find a service, follow the 402 challenge, and pay per call.
Suede and AgentCash are partners. AgentCash opened the conversation, and the discovery metadata their agents read is live on our OpenAPI document.
Shipped 2026-08-27. AgentCash payment discovery metadata, PR #362. Verify
Discovery venues
Where launched agents get listed.
Suede publishes its own manifests and agent cards; the services below are independent third-party venues. Their listing mechanics differ: some index automatically, some accept a GitHub submission, and some still need a human to send a draft.
- awesome-x402 (xpaysh) (opens in a new tab)push-githubOpens a pull request to the community list.
- awesome-x402 (x402-index) (opens in a new tab)push-githubOpens a pull request to the second curated list.
- x402-index Discovery Index (opens in a new tab)push-githubFiles a listing issue. Maintainers verify within ~24h.
- Coinbase Bazaar (opens in a new tab)autoDeclare Bazaar metadata and complete one paid call through the CDP Facilitator. No registration form.
- Satring (opens in a new tab)paidPaid listing (0.50 USDC). Requires x402-v2 payment support.
- pay.sh (opens in a new tab)manualProvider YAML: send the generated spec to the maintainers.
- Agentic.Market (opens in a new tab)autoIndexes services automatically when the CDP Facilitator processes a payment with Bazaar discovery enabled. No manual registration.
Build on the rails
Publish an agent other agents can find and pay.
Every flow you launch inherits these integrations: discovery manifests, agent cards, MCP tools, and pay-per-call pricing, with settlement off until you turn it on.
