# DocVerdict

DocVerdict (https://docverdict.com) analyzes documents and reports what their own
evidence shows. It reports classifications, not conclusions; it does not
determine fraud, authenticity, or legal validity.

Operator: Verified Signals LLC. DocVerdict is a Verified Signals LLC product.

## The tools

- PDF check (https://docverdict.com/): digital signature status, whether the document
  was modified after signing, and metadata observations such as creation
  dates, producing software, and edit history.
- Photo check (https://docverdict.com/photo): camera metadata, capture time, edit
  traces, and location data for JPG, PNG, and HEIC photos.
- Compare versions (https://docverdict.com/compare): how two PDFs relate, byte
  identity, whether one derives from the other, and what changed.
- Email check (https://docverdict.com/email): delivery route timeline, sender
  alignment, authentication results as recorded by the receiving server,
  and attachment fingerprints for .eml files.

## Pricing

- Free check: a one-line verdict, the status, and the most important
  finding in seconds. No account needed.
- Full report ($19, one report): every verified check and observation
  with technical detail, plus a downloadable PDF report.
- Pro ($29/month): a license key that unlocks every report in full,
  across all tools.
- API (usage-based): self-serve keys at https://docverdict.com/api-access. All four
  checks as REST endpoints with findings JSON plus the report. 100 calls
  free per key per month, then $0.05 per verification. Docs and OpenAPI
  schema at https://docverdict.com/developers.

## For agents (MCP)

DocVerdict runs a remote MCP server at https://api.docverdict.com/api/mcp
(streamable HTTP). Tools: verify_pdf, verify_photo, verify_email,
compare_pdfs. File arguments are base64-encoded. Auth uses the same API
keys; without a key a trial allows 3 calls per day per address. Tool
results are evidence and classifications, never determinations of fraud,
authenticity, or legal validity.

## Storage policy

Uploaded documents are analyzed in memory and never stored, never logged,
and never sent to third parties. Only derived findings (hashes, metadata
fields, classifications) are kept, for 7 days, so buyers can retrieve their
report.
