How DocImprint compares to parsers, scrapers, verifiable agent memory, and interaction-receipt protocols — plus a breakdown of every extract mode.
Firecrawl returns Markdown chunks without cryptographic proof of capture. DocImprint returns tamper-evident evidence bundles with manifest SHA-256, EIP-191 signatures, free offline verify, and x402 USDC pay-per-call for agents.
LlamaParse returns structured JSON with optional citations but no tamper detection. DocImprint binds captures to SHA-256 manifests, supports legal hold, on-chain notarization, and Merkle citation proofs verifiable offline.
VerifiedState and Engram are tamper-evident memory stores for agent beliefs and session knowledge. DocImprint captures PDFs and URLs into signed evidence bundles with Merkle-cited answers you can verify offline — document capture, not a general memory graph.
PEAC and similar systems sign interaction or settlement receipts (what tools ran, what was paid). DocImprint signs document captures and proves which source paragraphs support each claim. Same vocabulary; different object of proof.
Use DocImprint when agents or auditors must prove what a document said at capture time — legal, finance, compliance, and research workflows. Use scrapers for bulk Markdown when proof is not required. Closest parse tools are complements, not always replacements.
The core difference: only DocImprint produces cryptographic proof that a document has not been modified since capture.
| Firecrawl | LlamaParse | DocImprint | |
|---|---|---|---|
| Output | Markdown chunks | Structured JSON | Evidence bundle + hashes |
| Proof | None | Optional citations | Free offline verify |
| Agent pay | API keys | API keys | x402 USDC + API keys |
| Verify | — | — | Free offline + on-chain |
Firecrawl and LlamaParse are excellent tools for chunking and parsing. They do not produce cryptographic evidence or support agent-native x402 USDC payments.
Every mode is a single POST /v1/extract call. Mix lean and bundle per request.
