c10r implements the A2A (Agent-to-Agent) open standard, enabling your agents to discover, communicate with, and delegate tasks to agents built on any platform, by any vendor, using any framework. One protocol, universal agent interoperability.
A2A defines how agents find each other, how they exchange tasks, and how they deliver results -- using open web standards
A machine-readable manifest that describes an agent's identity, capabilities, supported skills, and authentication requirements. Published at a well-known URL for automatic discovery.
Agents exchange structured tasks over HTTP using JSON-RPC. Long-running operations stream progress via Server-Sent Events. Each task has a lifecycle: submitted, working, completed, or failed.
When a task completes, results are delivered as typed artifacts -- structured data, documents, files, or any content both agents can parse. Each artifact has a MIME type and schema for reliable processing.
When you deploy agents on c10r, the platform automatically exposes A2A-compatible endpoints for each agent. External agents discover your capabilities through the Agent Card, submit tasks through the standard JSON-RPC interface, and receive results as structured artifacts.
No proxy servers, no custom API gateways, no protocol translation layers. c10r handles the A2A protocol natively so your agents are immediately interoperable with the broader ecosystem.
A2A is not a proprietary protocol. It is an open specification developed by Google with contributions from over 50 technology partners -- Salesforce, SAP, ServiceNow, LangChain, and more. Enterprise consulting firms including Accenture, BCG, and McKinsey are deploying A2A across their client portfolios.
By supporting A2A natively, c10r ensures your agents can interoperate with the growing ecosystem of A2A-compatible platforms and services -- without custom integration work for each new partner.
A2A enables scenarios where agents from different organizations collaborate on shared tasks. A procurement agent from one company can negotiate terms with your sales agent. A logistics agent can coordinate delivery schedules with your operations agent. An HR system's agent can request onboarding documents from your compliance agent.
These interactions happen through the standard protocol -- no bilateral API agreements, no custom webhooks, no manual coordination.
Interoperability does not mean open access. Every A2A interaction requires authentication. You control which skills are exposed to external agents, what data they can access, and what actions they can trigger. Internal agents operate with full permissions; external agents see only what you explicitly publish.
c10radds workspace-level A2A policies on top of the protocol's built-in security. Enable or disable external A2A access with a single toggle, or configure fine-grained per-skill permissions.
The A2A protocol is becoming the standard for how agents interoperate across platforms. Deploy on c10r and your agents join this global network -- discoverable, interoperable, and ready for the agent economy.
