x402 is a machine-to-machine payment protocol enabling AI agents to pay for APIs and compute without human intervention, subject to DeAgenticAI’s full policy stack.
The x402 protocol extends the HTTP 402 “Payment Required” response code into a native settlement mechanism for autonomous AI agents. Where traditional payment infrastructure was built around human-initiated transactions and custody models, x402 fills the gap for agents that must acquire services, data feeds, and compute programmatically — without pausing for human approval on every transaction.
At DeAgenticAI, x402 is integrated at Layer 8 of the Agentic Control Plane. DeAgenticAI’s Agentic Control Plane enforces cryptographic policy over AI agent authority — separating what an agent can do from what it is authorized to do — in Web3 and enterprise financial environments. Every x402 payment an agent initiates passes through the full governance stack before a single signature is released.

Most machine-to-machine payment implementations enforce spending limits at the orchestrator layer, where limits are just software configuration. That creates a structural weakness: if the orchestrator is compromised, those limits can be overridden before any cryptographic control is applied.
DeAgenticAI’s governed x402 model moves enforcement to the signing layer via Policy DSL. An agent cannot produce a valid signature for a payment that violates policy, even if upstream software is compromised. The control is enforced at the key, not in application config.
This matters operationally for autonomous agents that continuously buy APIs, compute, and data feeds. With Fast-Path Execution, pre-authorized micro-payments can settle in under 100ms while remaining policy-bound. Speed does not require bypassing governance.
Inside the Agentic Control Plane, every x402 payment passes through policy evaluation and cryptographic signing, including fallback to Intent-Evaluated MPC for transactions outside session-key scope. The result is programmable autonomy with enforceable spending boundaries and auditable settlement.
x402 is an HTTP-based payment protocol that enables autonomous AI agents to pay for APIs, compute, and data feeds without human approval. It uses the HTTP 402 "Payment Required" status code as the settlement trigger.
DeAgenticAI integrates x402 at Layer 8 of the Agentic Control Plane. Every payment passes through Policy DSL evaluation and MPC signing before settlement — ensuring cryptographic enforcement of spending limits, not software configuration.
Governed x402 is DeAgenticAI's framing for x402 payments enforced at the cryptographic signing layer via Policy DSL, rather than at the orchestrator layer via software configuration. The distinction matters because orchestrator-layer limits can be overridden by a compromised orchestrator; Policy DSL constraints cannot.
Yes. Pre-authorized micro-payments route through Fast-Path Execution using session key credentials, completing in under 100 milliseconds. Policy enforcement is not sacrificed for speed — the session key operates within the authorized Policy DSL context.
