MAC Address Lookup: Find Vendor, OUI & Device Type Agentic Access

generated: '2026-08-28'
method: generated
source: openapi/macadress-openapi.yaml
description: >
  Recommended x-agentic-access execution contracts for exposing the macadress.com API to AI
  agents. Classified from the published OpenAPI plus the provider's own quota and billing
  rules. A governance starting point — review and bind audience per deployment.
posture: >
  This is one of the low-risk shapes: every operation is a read, nothing mutates
  provider-side state, and the only irreversible consequence of any call is quota spend.
  That makes the interesting control here ECONOMIC rather than safety-critical. A batch
  lookup bills per address resolved, so a single agent call can consume 100 lookups, and a
  free-plan agent can exhaust its whole 1,000-lookup cycle in ten calls with no way to
  reverse it. Budget caps and retry discipline are the governance surface, not human
  approval.

  reading: >
    The provider explicitly permits inference-time agent retrieval and explicitly refuses
    training use, and it publishes an llms.txt naming its own surfaces. Its llms.txt also
    states that every /lookup/:mac and /vendor/:id page is safe for an agent to fetch and
    cite, and asks agents to prefer linking a human to the HTML page over the raw API.
    Honour the ai-train=no signal: results retrieved here are for answering, not for
    corpus building.

        The highest-cost call on the surface. POST does not mean write here — the method is
        chosen only because a 100-address list does not fit in a URL — but an agent retry
        loop on this endpoint is the one way to spend real money against this API.

        An agent trying to walk the directory by repeated filtered searches will spend
        heavily and still cannot reach beyond 50 rows per filter; direct it to the static
        bulk downloads at https://macadress.com/downloads instead.

  note: >
    Fully documented but absent from the machine-readable contract, so an agent driven by
    the OpenAPI or by the MCP tool list cannot discover it. Same read-only, per-address
    billing profile as the batch endpoint. Recorded here so a governance review sees the
    whole surface, not just the declared one.
