# Artefaktum Artifact Lineage / Relations

> Artefaktum Artifact Lineage / Relations is a paid API for AI agents from api.artefaktum.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-01).

Returns an artifact's lineage graph: the artifacts it was derived from (parents) and those derived from it (children), with relation type and direction.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability artefaktum-artifact-lineage-relations-90cfe68c
```

Example prompt: Show me the full lineage for artifact abc123 on Artefaktum — I want to see both what it was derived from and what has been derived from it, along with the relation types.

## When to prefer this

Use this endpoint when you need to understand the provenance or downstream impact of a specific artifact stored in Artefaktum — i.e., which artifacts it was built from and which artifacts were built from it. Prefer this over generic artifact metadata endpoints when lineage, derivation chains, or dependency auditing is the goal.

## Known failure modes

- artifact_id not found — 404 with error message
- wallet has not paid or account not initialized — 402 payment required
- invalid artifact_id format — 400 bad request
- artifact belongs to a different wallet — 403 forbidden
- network timeout or service unavailable — 503

## How this service works

List an artifact's lineage: the artifacts it was derived from and those derived from it, with relation type and direction. Costs $0.005 in USDC. No signup: a wallet's first payment creates its account and a default project; the same wallet later reaches the same files.

## Output

A JSON array of relation objects, each describing a linked artifact with its relation type (e.g. derived_from, derived_into) and direction (parent or child), allowing the caller to reconstruct the artifact's full provenance graph.
