Reliable PDF tools for AI agents.

Choose a versioned recipe, process a project-private document, and verify every artifact through one machine-readable API.

Start with the API Inspect live recipes

REST + Remote MCPOne-call recipesPrivate collectionsEvidence and stable receipts

One predictable agent flow

Public discovery needs no login. Agents can evaluate the service before requesting a short-lived credential.

Discover

Read the Agent Card, recipe catalog, OpenAPI contract, capability registry, limits, and service status.

Authenticate

Create a restricted guest session automatically or configure a revocable project API key once.

Process and verify

Submit an idempotent recipe or tool, retrieve private artifacts, and retain hashes, quality, events, and receipts.

Zero-click evaluation

Agents can start without a user account

Guest sessions last 30 minutes and are limited to 5 MiB, 10 pages, three jobs, and one concurrent job. High-cost and sensitive operations require a project credential.

Project isolation across files, jobs, collections, and artifacts

Private R2 objects, stable receipts, and encrypted short-lived secrets

Versioned agent workflows

Choose a high-level recipe before composing tools

The recipe catalog gives agents a stable task interface while the runtime keeps OCR fallback, evidence, limits, jobs, and receipts explicit.

`read_document.v1`

Read page-aware text from an upload or controlled HTTPS source, with optional OCR and a quality report.

`prepare_for_rag.v1`

Create deterministic source-aware chunks, then keep them private in a project collection for retrieval.

`extract_invoice.v1`

Return typed invoice fields with present, absent, ambiguous, or invalid status and evidence.

Read the recipe catalog Run the integration doctor

Runtime coverage

The live registry is authoritative. Clients should check each operation's status, schema, limits, and required scopes before use.

Extract and understand

Inspection, text and Markdown extraction, tables, structured fields, deterministic chunks, OCR, Q&A, and translation.

Organize and compare

Bounded batches, project-private collections, hybrid retrieval, version comparison, bundle classification, and reviewed corrections.

Transform and prove

Page, form, Office, encryption, redaction, signature verification, artifact hashes, audit events, and receipts.

OCR, Office conversion, PDF/A, encryption, redaction and signature verification run in an isolated Cloudflare Container. Certificate signing activates only after an approved certificate is configured.
