Document Processing API | Parsewise
Parsewise
RESTful document-processing API for structured data extraction and cross-document reasoning to integrate document intelligence into apps.
Key features
- RESTful API: A simple HTTP API to upload or reference documents and receive structured JSON outputs suitable for integration into web services, backends, and pipelines.
- Structured Data Extraction: Extracts entities, key fields, tables, and relations from documents into normalized, machine-readable structures for downstream processing and analytics.
- Cross-Document Reasoning: Links facts and entities across multiple documents to answer queries that require aggregation, deduplication, or inference across a document set.
- Multi-format Ingestion: Accepts a variety of document formats and returns consistent structured outputs so applications can process PDFs, text, and other documents through a single endpoint.
- Searchable Outputs: Produces structured records and metadata that can be indexed or used directly for semantic search, filtering, and fast retrieval in applications.
- Integration-Focused Documentation: Designed for developer integration with clear REST semantics and predictable JSON responses so teams can onboard quickly and automate workflows.
- Scalable Processing: Built to handle batch and high-throughput document workloads so organizations can process large document volumes without managing ML infrastructure.
- Data Governance & Controls: Provides programmatic controls for document routing and structured output handling to support secure integrations and enterprise workflows.
- RESTful API endpoints for document ingestion and processing
- Structured data extraction (fields, entities, tables) from documents
- Cross-document reasoning and aggregation across multiple documents
- JSON-friendly outputs suitable for integration into apps and pipelines
- Designed for integration into existing technology stacks
Best for
- Automated Invoice Processing: Ingest invoices and extract supplier, totals, line-items, and dates into structured records for accounts payable automation.
- Contract Intelligence: Extract clauses, obligations, and parties from legal documents and link related contracts to answer cross-contract queries.
- Knowledge Base Construction: Convert internal reports, manuals, and documents into indexed structured records that support semantic search and enterprise Q&A.
- Compliance & Audit Trails: Pull structured facts from documents and correlate them across sources to create auditable evidence for regulatory checks.
- Claims Processing: Extract claimant information, policy details, and incident descriptions from submitted documents and reconcile across multiple files.
- Mergers & Acquisitions Diligence: Aggregate and reason over financial statements, contracts, and reports from multiple entities to surface linked insights.
- Automated extraction of structured data from invoices, receipts, and forms
- Contract analysis and extraction of key clauses/terms across a corpus
- Building searchable knowledge bases from collections of documents
- Cross-document reconciliation and entity linking for compliance and auditing
- Feeding extracted structured data into downstream workflows and analytics
Velane
Velane
Open-source integration infrastructure for AI agents — 800+ OAuth-connected APIs, sandboxed runtimes, and dev/staging/prod promotion via MCP.
Key features
- 800+ OAuth Integrations: One connection lets agents call Salesforce, Stripe, Slack, HubSpot, Notion, GitHub, Linear, Zendesk and hundreds more via the Nango catalog.
- MCP-Native Interface: Agents connect to mcp.velane.sh and drive discovery, code generation, execution, and deployment through a single MCP server.
- Bun & Python Sandboxes: Every invocation runs in an isolated ephemeral runtime, so agent code can be tested safely without touching production state.
- Dev / Staging / Prod Environments: Promote workflows through three environments with agent-issued publish_snippet calls and stable versioned HTTP endpoints.
- Shared Credential Store: One OAuth connection per provider is reused across every team member's agent — no secret ever appears in code.
- Invocation Logs & Audit Trail: Per-tenant execution logs let agents call get_logs to debug failures and give teams a full audit history.
- Role-Based Access: Invoke, manage, and admin scopes control what each teammate's agent is allowed to do.
- Self-Host or Hosted: Run Velane on your own infrastructure under AGPL-3.0 or use the managed mcp.velane.sh endpoint.
Best for
- Agent-Built Stripe→HubSpot Automations: An agent in Cursor writes a Bun workflow that reads Stripe customers and pushes them into HubSpot, tests it in dev, and promotes to prod in one conversation.
- Solo Developer Shipping SaaS Integrations: A single developer wires up Slack, Notion, and GitHub actions without maintaining an OAuth backend.
- Multi-Tenant B2B Agent Products: A team runs Velane per tenant so each customer's agent has isolated credentials, sandboxes, and audit logs.
- Safe Refactors of Live Workflows: Deploy a new version of a workflow to staging, verify with logs, then roll to prod with instant rollback.
- MCP-First Prototyping: Prototype an entire integration pipeline from an IDE chat without spinning up backend infrastructure.
