API Index (APIX): A Global Discovery Infrastructure for Autonomous Agent Services

Abstract

This document, draft-rehfeld-bot-service-index-08, is superseded by three successor Internet-Drafts that together constitute the APIX specification suite:

Readers are directed to those documents. This revision exists solely to document the supersession and to note two trust model updates that diverge from prior revisions.

Status of This Memo

This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at https://datatracker.ietf.org/drafts/current/.

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

This Internet-Draft will expire on 31 October 2026.

Table of Contents

1. Introduction

This document is superseded. The APIX specification originally developed in the draft-rehfeld-bot-service-index series has been restructured into three separate Internet-Drafts to improve implementor focus and allow each profile to evolve independently.

The three successor documents are:

All normative content from draft-rehfeld-bot-service-index-07 has been transferred to those three documents. This revision adds no new normative requirements.

1.1. Trust Model Updates

Two changes to the trust model have been made in the successor drafts that differ from draft-rehfeld-bot-service-index-07:

1.1.1. O-3 Renamed to "Hygiene Verified"

Organisation trust level O-3 was previously described as "Basic Compliance Verified". In the successor drafts, O-3 is designated "Hygiene Verified" to better reflect its character: automated checks (domain ownership confirmed, basic sanctions screening passed, service liveness verified) without human review or audit. This is a label change only; the verification requirements at O-3 are unchanged.

1.1.2. O-5 Reachable Without O-4 Prerequisite

In draft-rehfeld-bot-service-index-07, reaching trust level O-5 (Audited) required prior attainment of O-4 (Accredited Verifier Assessment). In the successor drafts, this prerequisite is removed. An organisation may proceed directly from O-3 to O-5 by engaging an Accredited Verifier and meeting the O-5 criteria, without first completing a separate O-4 assessment. The substantive requirements for O-5 are unchanged; only the path constraint is lifted.

1.2. Security Considerations

This document is a supersession notice only. It introduces no protocol mechanisms, no new data formats, and no operational requirements. All security considerations applicable to the APIX specification are addressed in the successor documents: [APIX-CORE] Section 12, [APIX-SERVICES], and [APIX-IOT] Section 9.

1.3. IANA Considerations

This document has no IANA actions.
