Which one, for what

Extend API + MCP B

Good for Teams building production extraction with evaluation sets and versioned processors, and for agents that need to build or tune extractors as well as run them.

Ahead on

  • Reliability, 67 against 43
  • Maintenance & community, 82 against 65
  • Transparency & trust, 67 against 47

Watch for

Parse is billed on top of Extract, Split and Classify, so Performance Extract costs 5 credits a page

OpenDocRouter C

Good for Agents that need page-level markdown from PDFs and images and want to choose or compare models on price and published benchmark scores with one key.

Ahead on

  • Agent ergonomics, 84 against 68

Verdicts

Extend API + MCP

Hosted MCP with OAuth scoped to workspaces and to test or production, and a tools filter with nine groups. Parse is billed on top of Extract, Split and Classify, so Performance Extract costs 5 credits a page.

OpenDocRouter

One endpoint reaches 11 parsing models, each with a dated recipe version, a published token price and a ParseBench score, and failed pages aren't charged. The service launched on 7 October 2026, so it has no status page, incident history, SLA or changelog yet, and no key scopes were found in the reviewed documentation.

Before you call either

Extend API + MCP

  1. Connect with https://mcp.extend.ai/mcp?tools=parse,extract,files to keep the schema small
  2. Every MCP call names a workspace and TEST or PRODUCTION; start in TEST
  3. Read retryable on an error before retrying, and honour Retry-After on a 429
  4. Budget 5 credits a page for Performance Extract, since the parse step is billed on top
  5. Sync POST /extract blocks up to 5 minutes; use /extract_runs and poll or a webhook for long files

OpenDocRouter

  1. Call GET /v1/models first, which needs no key, and choose a model by avg_charge_per_page_usd and its ParseBench scores. Send its id as model
  2. Send cache: true on any request you might repeat. Without it the markdown exists only in the POST response and a resend is charged as a new request
  3. Raise the SDK timeout above its 60-second default for sync parses. Pages can run for 270 seconds and the SDKs retry a timed-out request twice
  4. Check every page's status before using its markdown. A 200 can be partial, and failed pages can be resent alone with pages
  5. Treat 402 as final until credit is added. The hold is the model's maximum charge per page times the page count, and GET /v1/credits shows available_usd

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
