| Term | Definition |
|---|---|
| **APIX** | API Index — the global, neutral, machine-queryable registry of services for autonomous agents |
| **BSM** | Bot Service Manifest — the structured metadata document that describes a machine-consumable service (capabilities, endpoint, trust level, pricing) |
| **Spider** | The automated APIX crawler that periodically checks liveness and spec compliance of registered services |
| **O-level** | Organisation trust level (O-0 to O-5). O-0: unverified. O-1: domain ownership confirmed. O-2: legal entity verified. Higher levels require additional compliance verification. |
| **S-level** | Service trust level. Reflects technical verification of the service against its declared BSM spec. |
| **Liveness** | Operational status of a registered service as last measured by the Spider. States: `pending`, `live`, `degraded`, `unreachable`. |
| **AE** | Agent Enterprise — an autonomous agent that composes APIX-registered services into a workflow and potentially earns on each execution |
| **HATEOAS** | Hypermedia as the Engine of Application State — REST architectural constraint where the client navigates entirely via links returned by the server; no out-of-band URL knowledge required |
| **DC-1** | Device Class registration — the APIX registration record for an IoT device class (BSM template); persists beyond the original operator's cloud service lifetime |
| **Capability** | A machine-readable tag describing what a service does (e.g., `inventory.read`, `slot.book`, `customs.doc`). The primary search dimension in APIX. |
| **GLEIF** | Global Legal Entity Identifier Foundation — the data source used for automated O-2 legal entity verification |
| **Internet-Draft** | `draft-rehfeld-bot-service-index-00` — the IETF submission that formalises the APIX specification |
| **PoC** | Proof of Concept — the MVP deployment described in this document |
| **STF** | Sovereign Tech Fund — the German federal funding body; primary target for APIX infrastructure funding |
| **BSF** | Bot Standards Foundation — the Swiss Stiftung that governs the APIX standard and operates the reference index |
| **UPSERT** | Insert-or-update DB operation — used for re-registration: same endpoint URL updates existing record rather than creating a duplicate |
