Overall verdict

  • WTM API appears to be a niche data/API service, but without verified, independent, up-to-date information confirming its reliability, uptime, pricing transparency, or customer support quality, it's not possible to give a confident endorsement. Prospective users should conduct due diligence, test the API with a trial or sandbox account, and verify documentation quality and support responsiveness before committing.

Why this product is good

  • Limited independent reviews or third-party benchmarks are readily available to verify claims of performance and reliability.
  • Pricing and feature transparency should be confirmed directly on their site since public information is sparse.
  • API-based services can vary widely in documentation quality, so checking their developer docs firsthand is essential.
  • Support responsiveness and SLA guarantees are not well-documented externally, so direct testing is recommended.

Recommended for

  • Developers who are willing to test the API firsthand via a trial before committing.
  • Businesses needing a specific niche data feed that WTM API claims to provide, provided they verify data accuracy first.
  • Technical teams comfortable evaluating API uptime and documentation quality independently.
  • Not recommended for mission-critical production use without a thorough vetting period.

Questions & Answers

As answered by people managing Markdown-it and WTM API.

What makes your product unique?

WTM API's answer:

WTM API focuses on structure preservation, not just text extraction. Unlike most scrapers that return raw text, it converts HTML to proper Markdown with headings, tables, code blocks, and links intact. No headless browser needed — pure server-side parsing means sub-second responses at a fraction of the cost.

Why should a person choose your product over its competitors?

WTM API's answer:

Speed and simplicity. One POST call, any URL, clean Markdown back in under 1 second. No SDKs to install, no headless browser to maintain, no complex configuration. Generous free tier (50 calls/month) and straightforward pricing. The output is immediately usable for LLMs, RAG pipelines, or content migration.

How would you describe the primary audience of your product?

WTM API's answer:

Developers building AI/LLM applications, RAG pipelines, content migration tools, or any system that needs web content in a structured, portable format. Also useful for teams moving content to Markdown-based platforms like Notion, Obsidian, or static site generators.

What's the story behind your product?

WTM API's answer:

I was building a RAG pipeline and needed web content in Markdown format. Existing tools gave me either raw text (losing all structure) or required a headless browser (slow and expensive). I built WTM API to solve my own problem - a fast, simple API that preserves the structure of any webpage as clean Markdown. Shipped the MVP in a weekend using Next.js, Supabase, Stripe, and Vercel, all on free tiers.

Which are the primary technologies used for building your product?

WTM API's answer:

Next.js 16 (App Router), Supabase (auth and PostgreSQL), Stripe (subscription billing), Vercel (hosting), and Cheerio (server-side HTML parsing). The entire stack runs on free tiers with zero monthly infrastructure cost.

Who are some of the biggest customers of your product?

WTM API's answer:

  • Early-stage AI startups building RAG pipelines
  • Independent developers working on content tools
  • Currently in public beta and growing the user base
