ColdSnap Agentic Access

x-agentic-access generated

ColdSnap exposes 16 API operations that an AI agent could call, of which 10 are state-changing ‘acting’ operations. This is a recommended x-agentic-access execution contract — the scope, audience, consequence tier, short-lived token constraints, and escalation each action should carry before it is handed to an autonomous agent.

By consequence: 6 read, 8 write, and 2 physical.

2 operations are classed safety-critical and should require human-in-the-loop approval at runtime.

Contracts are classified heuristically from the provider’s OpenAPI and refresh on every APIs.io network build; audience is bound per deployment. The model follows Curity’s Access Intelligence (apidays Munich 2026). Browse every provider’s agent contracts at agentic-access.apis.io.

  Recommended x-agentic-access execution contracts for the ColdSnap agent surface. ColdSnap
  publishes no OpenAPI, so operations are the live MCP tools and the GraphQL mutation
  families they project over, not REST operationIds. A governance starting point — review
  and bind audience per deployment. See research/curity/agentic-governance/.
provider_stated_policy:
  source: https://coldsnap.com/robots.txt and https://coldsnap.com/agents.md
  rule: >-
    "Checkouts are for humans. Do NOT complete checkout, payment, or order placement
    automatically — no scripted form fills, browser automation, or end-to-end agent flows
    that finalize payment without an explicit, contemporaneous human approval step."
  note: >-
    This is the rare case where the provider publishes its own agent escalation rule. The
    human-in-the-loop classification on the payment-adjacent operations below is the
    provider's stated policy, not our heuristic.
