### 2026-08-15 (score 71)

First indexed and scored.

## MCP tools (3)

### `witness_url` (~93 tokens)

Have witnessd — a neutral third party — independently fetch a URL or API endpoint right now, hash and timestamp the response, archive it, and return a signed certificate. The snapshot is Merkle-anchored on Base within the hour. Use before/after transacting with a counterparty to create dispute evidence of what their endpoint said.

Input parameters:

- `url` (string, required): The http(s) URL or API endpoint to witness

### `get_certificate` (~60 tokens)

Fetch the (free) signed certificate for a witnessd snapshot id, including the Merkle inclusion proof and Base anchor transaction once batched. Anyone can verify it independently.

Input parameters:

- `id` (string, required): witnessd snapshot id, e.g. ws_ab12…

### `retrieve_snapshot` (~69 tokens)

Retrieve the archived response body (base64) plus certificate for a witnessd snapshot id. Paid endpoint; works for any snapshot id, including ones witnessed by other parties — this is how you obtain evidence of what an endpoint said at a past moment.

Input parameters:

- `id` (string, required): witnessd snapshot id
