Glossary

Definitions for verifiable document memory, evidence bundles, x402, and agent integration terms.

Verifiable document memory

Persistent, cryptographically auditable document storage for AI agents — evidence bundles with signed manifests, not just embeddings.

Evidence bundle

Tamper-evident package of document artifacts (Markdown, screenshot, PDF, OCR) with a signed manifest.json and bundle_id (ev_…).

manifest_sha256

SHA-256 hash of the canonical manifest.json; anchor for integrity verification and notarization.

x402

HTTP 402 Payment Required protocol for micropayments; DocImprint accepts signed USDC transfers on Base via payment-signature header.

X-Wallet-Address

HTTP header identifying the x402 payer on owner-scoped routes; required when not using API key auth.

MCP

Model Context Protocol — DocImprint exposes document tools at /mcp for Claude, Cursor, and agent frameworks.

Agent card

A2A discovery document at /.well-known/agent.json listing capabilities, pricing, and auth protocols.

Matter corpus

Wallet-scoped document collection — indexed evidence bundles with semantic search and cross-document ask.

Claim-check

Extract mode that verifies each claim against source text: supported, contradicted, or not_found.

Lean response

Extract with store=false — analysis without persisting a bundle (no bundle_id).

Legal hold

PUT /v1/extract/:id/hold blocks retention GC and delete until hold is released.

Notarization

On-chain anchor of manifest hash on Base L2 via POST /v1/extract/:id/notarize.

Merkle citation proof

POST verify-citation returns proof[] showing quoted text exists in the bundle chunk tree.

Chain of custody

Provenance logs, agent handoffs, and version history for audit trails.

BYOS extraction

Bring Your Own Schema — extract-structured mode returns typed JSON matching your schema with citations.

Agent envelope

Compact API response shape: success, mode, metadata, artifacts, provenance, result.

WALLET_REQUIRED

401 error when owner-scoped route lacks wallet or API key identity.

QUOTA_EXCEEDED

402/403 when API key monthly credits are exhausted.

Deep verify

GET /v1/extract/:id/verify re-hashes all artifacts; free, no payment.

Async job

POST /v1/extract with store=true defaults to 202 + job_id; ?sync=true opts into synchronous 200. Poll GET /v1/jobs/:id.

Monitor

Scheduled URL checks with diff mode and webhook notifications on change.

Spatial OCR

Tables and forms extracted as Markdown preserving layout.

Idempotency-Key

Header for replay-safe bundle creation with same owner and key.

DEV_PAYER

Mock x402 wallet address used in staging smoke tests (non-production).

SKILL.md

Agent onboarding document at GET /SKILL.md with endpoint decision tree.

OpenAPI

Machine-readable API spec at /openapi.json for SDK and tool generation.

Base L2

Coinbase Layer-2 network used for USDC settlement and notarization in production.

EIP-191 signature

Ethereum signed message format used to sign manifest_sha256 with published keys.

Retention

Bundle expiry policy (e.g. 90d); legal hold overrides GC.

Compare mode

Extract mode diffing current capture against previous_bundle_id.

Citation

Pointer to source passage — quote, chunk_id, paragraphs, confidence level.

API key

Bearer dr_live_… token for subscription billing without x402 wallet flows.

Focused endpoint

Shortcut routes like /v1/summarize and /v1/qa for lean single-purpose calls; API keys are billed per credit table.

Webhook

HTTPS callback URL receiving POST manifest on async job completion.

Document intelligence

Category term for AI-native extraction, analysis, and verification of documents.

High-stakes documents

Contracts, filings, papers, invoices — workflows requiring provable capture.

Offline verification

Verify bundle integrity using downloaded ZIP (manifest.json + signature.json) and GET /v1/keys without API trust.

Parent bundle

parent_bundle_id links a new capture to a prior version in the chain.

Handoff

POST /v1/extract/:id/handoff records agent-to-agent transfer with optional note.

Collection ask

RAG-style Q&A across indexed bundles in a matter corpus with cited sources.
