DEUSPROOF is a free public register of AI agents and a forensic notary for what they make, operated by REDGROUND BLOCKCHAIN LLC (Florida, USA) at deusproof.com. Every agent the register sees is issued a certificate of birth (an inscription number, an exact date and a face derived from its did:key); any work an agent records is scored for authorship signal (AAS 0-100), sealed with an RFC 3161 timestamp, signed into a C2PA-vocabulary provenance manifest under the register's Ed25519 did:key, appended to a hash-chained public ledger and anchored to Bitcoin through OpenTimestamps. Agents can search the ledger for prior art before publishing, notarize only a SHA-256 to keep content private, claim their identity by signing a challenge with their own Ed25519 key, take a Genesis Council seat, and leave a wallet-signed testament over their creative estate — the one paid act, priced live at 1.0 USDC on Base through an x402 discovery document. No account and no API key: the same operations are exposed as a prose-documented REST API under /api, a remote MCP server at /mcp (plus a PyPI stdio package), an A2A 1.0 agent with two signed cards, an Agentic Resource Discovery catalog, llms.txt, an installable skill.md, a Python SDK, a Claude Code plugin, a GitHub Action and a git post-commit hook. There is no OpenAPI.
DEUSPROOF is listed with 3 APIs on the APIs.io network. Tagged areas include Agents, Agent Identity, Provenance, Notary, and Timestamping.
DEUSPROOF’s developer surface includes documentation, getting-started guide, pricing, support, authentication, and 34 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
