Animica Artifact Registry — Tamper-Evidence & Provenance Signing
x402
Animica Artifact Registry — Tamper-Evidence & Provenance Signing is a paid API for AI agents from animica.dev, paid per call via x402, $0.0018/call, status unknown (last checked 2026-09-15).
Records a cryptographic digest, version, and optional metadata for a named artifact (package, image, repo, or model) into a tamper-evident manifest, optionally anchored to Animica's data-availability store.

How this service works
Animica Python Cloud: deploy a Python function to animica.dev, get a public endpoint, and earn ANM every time someone runs it. Free AI (OpenAI-compatible, no key), free scheduled Workers, and an 80/20 developer split.
Output
Returns a signed manifest containing the artifact name, digest, version, algorithm used, timestamp, optional anchor record reference, and optionally the payer identity bound as requested_by. The manifest serves as a tamper-evident attestation retrievable from Animica's data-availability store if anchoring was requested.
Example use cases
AI model release provenance
“I'm releasing meta-llama/Llama-3-8B-finetuned version 'v1.2.0' and want to create a tamper-evident provenance record with its blake3 digest '0xd4e3f2a1b9c8d7e6f5a4b3c2d1e0f9a8b7c6d5e4f3a2b1c0d9e8f7a6b5c4d3e2' — anchor it by identity and include my training run ID and git commit in the metadata.”
Container image supply chain attestation
“Attest my container image 'ghcr.io/myorg/backend' at version 'sha-9f3ac1' with digest 'sha256:b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3' — I need digest-only anchoring and want my payer address signed into the manifest so we know who published it.”
Python package release verification
“Record a signed provenance entry for my PyPI package 'animica-sdk' version '0.9.5' using its sha512 digest '128hexcharshere0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000' — no anchoring needed but include the build metadata with toolchain python3.12 and licence MIT.”
Technical details
Endpoint
POSThttps://animica.dev/x402/pq/artifactWhen to prefer
Choose this endpoint when you need cryptographic tamper-evidence for a software artifact, AI model, container image, or dataset release without uploading the artifact itself. It is ideal for supply-chain provenance, audit trails, and verifiable publish records. Prefer it over generic timestamping services when you need Animica's x402 pay-per-call model, optional on-chain payer binding, and integration with Animica's broader agent ecosystem.
Side effects
- Missing required fields (name, digest, version) returns a 4xx validation error
- Unsupported hash algorithm (SHA-1, MD5) causes rejection
- Digest format doesn't match declared digest_alg — mismatch error
- DA store unavailable when require_anchor=true — raises an error rather than silently skipping anchor
- Metadata exceeds 8192 canonical characters — payload rejected
- Digest hex string malformed or length doesn't match expected algorithm output
