Why DocImprint? - ๐Ÿ” **Cryptographic provenance** โ€” every bundle is EIP-191 signed at creation; optionally notarized on Base L2 via EAS for an immutable on-chain audit trail - ๐Ÿค– **Agent-native by design** โ€” async jobs, webhooks, idempotency keys, and legal hold built into every request, not bolted on - ๐Ÿ“Ž **Beyond OCR** โ€” citations carry exact quotes, paragraph indices, and confidence scores (`high`/`medium`/`low`), not just raw text - ๐Ÿ› ๏ธ **10 CrewAI tools out of the box** โ€” `research_tools()`, `legal_tools()`, `collection_tools()` pre-grouped for common agent workflows - โš–๏ธ **Compliance-ready** โ€” `legal_hold`, provenance logging, multi-agent handoff tracking, and on-chain notarization designed for legal and regulated industries - ๐Ÿ’ณ **Flexible payment** โ€” monthly credit plans or pay-per-call USDC via x402, no account required --- ## Agent-native features DocImprint is designed for autonomous agent workflows, not just synchronous API calls. ```typescript // Fire-and-forget async extraction โ€” returns job_id immediately const job = await client.extract({ source: 'https://example.com/large-report.pdf', async: true, webhook: 'https://your-agent.io/callback', idempotency_key: 'report-2025-q4', legal_hold: true, }) const status = await client.getJob(job.job_id) // { status: 'complete', bundle_id: 'ev_...', progress_pct: 100 } // Monitor a URL for changes โ€” get notified on diff await client.extract({ source: 'https://example.com/terms.html', monitor: { webhook: 'https://your-agent.io/changes', mode: 'diff' }, }) ``` **Python: provenance & multi-agent handoff tracking** ```python client.log_provenance(bundle_id="ev_...", agent_id="agent-research", action="extracted") client.handoff(bundle_id="ev_...", from_agent="agent-research", to_agent="agent-legal", note="ready for claim check") ``` --- ## CrewAI integration 10 purpose-built tools for CrewAI agents, organized into preset groups. ```python from docimprint.crewai import DocImprintToolkit toolkit = DocImprintToolkit( api_key="dr_live_...", collection_id="col_...", # required for collection tools ) toolkit.research_tools() # extract, summarize, qa, check_claims toolkit.legal_tools() # check_claims, verify, notarize toolkit.collection_tools() # search, ask, add_to_collection toolkit.all_tools() # all 10 tools ``` | Tool | What it does | |------|---| | `ExtractEvidenceTool` | Full evidence bundle with citations and manifest hash | | `SummarizeTool` | Key points with cited paragraph references | | `QATool` | Cited answer with confidence score | | `CheckClaimsTool` | Per-claim verdict: supported / contradicted / not_found | | `TranslateTool` | Source-cited translation | | `VerifyBundleTool` | Cryptographic integrity check โ€” manifest, hash, signature | | `NotarizeTool` | On-chain EAS attestation on Base L2 | | `SearchCollectionTool` | Semantic vector search across document collection | | `AskCollectionTool` | Cross-document RAG Q&A with cited sources | | `AddToCollectionTool` | Add bundle to collection and trigger async indexing | **ProvenanceTracker** wraps all tools to automatically log agent actions and bundle handoffs. ```python from docimprint.crewai import DocImprintToolkit, ProvenanceTracker tracker = ProvenanceTracker(client=toolkit.client) trackable = toolkit.trackable_tools() ``` **DocImprintKnowledgeSource** integrates with CrewAI's knowledge system for retrieval-augmented agents. --- ## MCP server DocImprint exposes a native MCP server for use with Claude, Cursor, and any MCP-compatible client. **Install via Smithery (one command):** ```bash npx @smithery/cli install docimprint --client claude ``` **Manual config:** ```json { "mcpServers": { "docimprint": { "type": "streamable-http", "url": "https://api.docimprint.com/mcp", "headers": { "Authorization": "Bearer dr_live_..." } } } } ``` Transport: `streamable-http` ยท Auth: Bearer token ยท [Listed on Smithery](https://smithery.ai/servers/sawftware-apps/docimprint) ยท [Listed on Glama](https://glama.ai/mcp/servers/docimprint) [![smithery badge](https://smithery.ai/badge/sawftware-apps/docimprint)](https://smithery.ai/servers/sawftware-apps/docimprint) ### MCP tools **URL tools** โ€” lean mode, no bundle stored: | Tool | Description | |------|---| | `extract_url` | Fetch URL โ†’ text + metadata | | `summarize_url` | Fetch URL โ†’ prose summary + key points | | `qa_url` | Fetch URL โ†’ cited answer to a specific question | | `translate_url` | Fetch URL โ†’ translated content | **Document tools** โ€” accepts base64 PDF or image: | Tool | Description | |------|---| | `extract_text` | OCR plain text from PDF / image | | `extract_tables` | OCR tables as Markdown from PDF / image | | `parse_invoice` | Structured invoice fields: merchant, line items, totals + citations | | `summarize_document` | Prose summary + cited key points | | `check_claims` | Per-claim verdict with evidence quotes | | `extract_structured` | Extract typed fields using a caller-defined schema | **Bundle & collections:** | Tool | Description | |------|---| | `verify_bundle` | Cryptographic integrity check (returns signed action receipt) | | `get_bundle` | Bundle metadata and notarization status (returns receipt) | | `notarize_bundle` | On-chain EAS attestation on Base L2 (returns receipt) | | `list_receipts` | List signed action receipts for a bundle | | `verify_action_receipt` | Verify a receipt signature + manifest binding | | `create_collection` | Create a named document collection | | `list_collections` | List your collections | | `add_document_to_collection` | Add bundle + trigger async indexing (returns receipt) | | `search_collection` | Semantic vector search | | `ask_collection` | Cross-document RAG Q&A | | `get_job_status` | Poll async job (extract, indexing, batch) | | `get_quota` | Check credit balance and plan status | **Guided prompts:** `claim_check_workflow` ยท `invoice_intake` **Resource:** `bundle://{bundle_id}` โ€” read bundle metadata directly --- ##

Authentication ### API key Monthly credits via Stripe โ€” sign up at [docimprint.com](https://docimprint.com), free tier available: ```typescript const client = new DocImprintClient({ apiKey: 'dr_live_...' }) ``` ### x402 USDC payments DocImprint supports the [x402 open standard](https://x402.org) โ€” pay per call in USDC on Base, straight from any EVM wallet. **No account. No sign-up. No API key.** Your agent can call the API autonomously without any human-managed credentials. The API is x402-native: it returns a standard `402 Payment Required` response with on-chain payment details, your client settles in USDC, and the request completes automatically. From $0.01 / call. **With `@x402/fetch` (automatic payment handling):** ```typescript import { wrapFetchWithPayment } from '@x402/fetch' import { createWalletClient, http } from 'viem' import { privateKeyToAccount } from 'viem/accounts' import { base } from 'viem/chains' const account = privateKeyToAccount('0x...') const wallet = createWalletClient({ account, chain: base, transport: http() }) const fetchWithPayment = wrapFetchWithPayment(fetch, wallet) const res = await fetchWithPayment('https://api.docimprint.com/v1/summarize', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ source: 'https://example.com/report.pdf' }), }) const data = await res.json() ``` **Identity on owner routes:** For `GET`/`DELETE` operations that require ownership (e.g. fetching your bundle), pass the `payment-signature` header from a prior payment response so the API can verify your wallet address without a separate login. --- ## TypeScript All request and response types are exported: ```typescript import type { ExtractRequest, ExtractResponse, Citation, CitedField, InvoiceResult, Job, Collection, SearchResult, } from 'docimprint' ``` --- ## Pricing Free tier available โ€” no credit card required.
