Ironfang
Ironfang Render is the rendering API from Ironfang Ltd, a UK software company that builds and operates self-service developer APIs. It turns a URL or a block of raw HTML into screenshots, PDFs, templated images, QR codes, captioned video clips and scrolling site previews over plain HTTPS and JSON, with no browser fleet for the customer to run. The v1 REST API is described by a published OpenAPI 3.1 contract covering 33 operations across synchronous rendering, reusable HTML templates, signed render URLs, durable asynchronous jobs, batches of up to 100, and webhook or S3-compatible delivery destinations. A remote MCP server at mcp.ironfang.com exposes the same core to AI assistants over OAuth 2.1 with a per-connection credit budget, and an llms.txt, a TypeScript and Python SDK, a CLI and an n8n node round out the surface. Plans are hard-capped rather than metered into overage, cache hits are free, and failed renders are refunded. Ironfang's own apis.json lists five more product APIs on the same account, portal and key format, each with its own published OpenAPI 3.1 contract under api.ironfang.com, for Audit (website evidence), Finance (e-invoice validation and generation, v1 and v2), Rig (disposable integration test environments), Analytics (session replay) and Security (external security checks).
Ironfang publishes 62 API contracts indexed on the APIs.io network, including Account API, Batches API, Destinations API, and 59 more. Tagged areas include Developer Tools, screenshot-api, website screenshot, HTML to PDF, and PDF API.
The Ironfang catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 1 Spectral governance ruleset.
Ironfang’s developer surface includes engineering blog, documentation, changelog, authentication, CLI, sandbox, getting-started guide, and 34 more developer resources.
