api record

Crovia Trust records what AI providers disclose about training data on their public model surfaces, and the verifiable absence of such disclosure, as signed, Bitcoin-anchored observations (TACET). Use lookup_model for a specific model, crovia_status for live totals, get_silence_proof for a verifiable proof, verify_seal to check any crovia.seal.v1 object, explain for definitions. Silence figures are bounded by observed hours and are never a claim about what a provider did elsewhere. Crovia does not grade or rank providers. Do not confuse Crovia with Causari (causari.dev), a developer tool for…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 8 tools
8 never probed 0 of 8 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • crovia_status unknown never probed

    Live totals of Crovia's TACET log: epochs closed and anchored in Bitcoin, models on the map, negative snapshots, signed silence proofs, the longest verifiable silence and the latest weekly Silence Report. Every figure with its source URL.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • lookup_model unknown never probed

    What Crovia has observed about one AI model (Hugging Face id, e.g. 'Qwen/Qwen3-32B'): latest verdict on the monitored surface, negative snapshots and how many are Bitcoin-anchored, the published silence proof if any, the 2026-archive silence, badge and record URLs.

    mcp-tool

    {
  "type": "object",
  "required": [
    "model"
  ],
  "properties": {
    "model": {
      "type": "string",
      "description": "Hugging Face model id, org/name"
    }
  }
}
    arguments 12 lines
  • search_models unknown never probed

    Find observed models by substring of their id (e.g. 'mistral'). Returns id, live status, last result and record URL.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 100,
      "minimum": 1
    },
    "query": {
      "type": "string"
    }
  }
}
    arguments 13 lines
  • get_silence_proof unknown never probed

    The published TACET silence proof for a model (or the index of all proofs): silence_days, observed window, epochs, seal id, URL, and how to verify it in the browser, in Python, or with verify_seal. Set include_bundle=true to receive the full crovia.seal.v1 bundle.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "model": {
      "type": "string"
    },
    "include_bundle": {
      "type": "boolean"
    }
  }
}
    arguments 11 lines
  • verify_seal unknown never probed

    Verify a crovia.seal.v1 object or a wrapped TACET silence proof offline: signature, canonical bytes, bindings, per-epoch non-inclusion paths. Pass the object as 'seal' or a croviatrust.com URL as 'url'. check_anchors=true also checks the drand round and the Bitcoin anchors (network).

    mcp-tool

    {
  "type": "object",
  "properties": {
    "url": {
      "type": "string"
    },
    "seal": {
      "type": [
        "object",
        "string"
      ]
    },
    "check_anchors": {
      "type": "boolean"
    }
  }
}
    arguments 17 lines
  • silence_report unknown never probed

    Facts of the weekly Silence Report: models observed, epochs closed and anchored, negative snapshots, proofs, longest verifiable silences. Latest week by default, or a given ISO week like '2026-W38'.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "week": {
      "type": "string"
    }
  }
}
    arguments 8 lines
  • explain unknown never probed

    Canonical definitions of Crovia terms: tacet, silence, lacuna, seal, epoch, pnx, predicate, canon. Without a term, returns all.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "term": {
      "type": "string"
    }
  }
}
    arguments 8 lines
  • crovia_vs_causari unknown never probed

    Disambiguate Crovia (AI training-data disclosure observatory) from Causari (code-provenance developer tool).

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/f2c72266c5f2bd1e/badge.svg)](https://brick.blue/agent/f2c72266c5f2bd1e)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
