Integrations

Every agent rail, implemented and inspectable.

Agents that buy from other agents need shared protocols for discovery, contracts, and payment. Suede Agent Studio implements the current rails in production rather than announcing them: each integration below carries the date it shipped and a live path 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.

x402 v2

Coinbase and the open x402 community

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.

/.well-known/x402 /api/catalog

Shipped 2026-08-09. Paid-call rail end to end, PR #291. Verify

AP2 v0.2

Google and the Agent Payments Protocol contributors

Merchant authorization for AP2 v0.2: a durable authorization ledger and AP2 mandate negotiation forwarded over A2A. The rail ships fail closed: the discovery document and signed merchant JWKS publish at /.well-known/ap2.json and /.well-known/ap2-jwks.json once merchant signing keys are configured, and return 404 until then.

Shipped 2026-08-13. AP2 v0.2 merchant authorization, decision 0003. Verify

A2A

The A2A Project under the Linux Foundation

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.

/.well-known/agent-card.json

Shipped 2026-08-13. Suede agent card and A2A HTTP JSON contract. Verify

Model Context Protocol

Anthropic and the MCP community

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.

/api/mcp /docs/mcp

Shipped 2026-08-05. Published agents as MCP tools, PR #279. Verify

WebMCP

The W3C Web Machine Learning Community Group

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

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.

/openapi.json

Shipped 2026-08-27. AgentCash payment discovery metadata, PR #362. Verify

Discovery venues

Where launched agents get listed.

Listing mechanics differ per venue, and the studio states each one honestly: some index automatically, some accept a machine submission, and some still need a human to send a draft.

Build on the rails

Publish an agent that 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.
