What is DocImprint?

DocImprint turns any PDF or URL into a tamper-evident evidence bundle — structured data, AI-cited answers, and a cryptographic proof your agents can verify independently.

| Feature | Description | |---------|-------------| | Extract | Markdown, tables, structured data, invoice parsing | | Summarize & Q&A | AI answers with inline citations and confidence scores | | Claim-check | Verify factual claims against the source document | | Collections | Cross-document semantic search and Q&A | | Notarize | On-chain attestation via Base L2 (EAS) | | MCP server | Native tool support for Claude, GPT, and any MCP client | | x402 payments | Pay per call with USDC — no account required |

Install

npm install docimprint

Quick start

import { DocImprintClient } from 'docimprint'

const client = new DocImprintClient({ apiKey: 'dr_live_...' })

// Extract a PDF and get a verifiable evidence bundle
const result = await client.extract({
  source: 'https://example.com/contract.pdf',
  include: ['markdown', 'summary'],
})

console.log(result.bundle_id)        // ev_01j...
console.log(result.summary)          // AI-generated summary
console.log(result.manifest_sha256)  // tamper-evident hash
