TL;DR: PlainID says AI agents are becoming the dominant class of API consumers, while Gartner’s 2026 Hype Cycle for APIs highlights a gap in gateway-era controls that were built for traffic, not identity-aware decisions at the moment of access. Runtime authorisation becomes the decisive control when scope, context and intent must change per call.
Editorial analysis by NHI Mgmt Group, based on content published by PlainID: “PlainID Named as a Sample Vendor in the Gartner® Hype Cycle™ for APIs, 2026”.
Key questions
Q: What breaks when AI gateway controls are treated like ordinary API security?
A: Ordinary API security assumes stable clients and predictable request paths.
Q: Why do AI agents increase the risk of over-privileged API access?
A: AI agents often need to move across systems quickly and may reuse the same identity for multiple actions.
Q: How do teams know runtime policy is actually working for API consumers?
A: You should see access decisions changing with context, narrow permissions at the moment of call, and removal of scope once the task ends.
Practitioner guidance
- Define runtime authorisation boundaries for agents Map which API actions require per-call policy evaluation, and separate those from low-risk traffic controls that gateways can still enforce.
- Scope agent access by identity, context and intent Require the policy engine to evaluate who the agent is, what context it is operating in and what task it is trying to complete before permitting sensitive calls.
- Replace persistent agent permissions with zero standing privileges Grant sensitive API scope only for the duration of the task and remove it when the workflow completes or context changes.
Bottom line: AI agents are pushing API governance beyond gateway-era traffic control and into identity-aware runtime authorisation.
What's in the full announcement
PlainID's full post covers the operational detail this post intentionally leaves for the source:
- How the platform applies central policy authoring across distributed API enforcement points
- How identity, context and intent are combined at the moment of access for agent calls
- How zero standing privileges changes runtime access decisions for machine consumers
- How the article positions human, non-human and AI agent identities under one policy model

Runtime authorisation is becoming the control plane for AI agent API access. The article correctly identifies that gateways are a traffic layer, not an identity decision layer. When AI agents are the caller, the control question becomes whether the request is permitted in this context, for this intent, at this moment. Practitioners should treat policy evaluation at access time as a primary governance function, not a late-stage enhancement.
A few things that frame the scale:
- According to PwC, 79% of organizations have already adopted AI agents to some degree.
A question worth separating out:
Q: How should security teams evaluate a platform that covers human, NHI, and AI agent identities?
A: Evaluate it by asking whether it preserves distinct governance semantics for each identity type. Human IAM, NHI lifecycle, and AI agent delegation do not fail in the same way, so a single console is not enough. The key test is whether ownership, evidence, and enforcement remain clear when identities are mixed in one operating model.
