Compare Felo OpenAPI and OpenRouter — pricing, model access, tool APIs, and which platform gives AI agents the most capabilities.

OpenRouter popularized the idea of one API key for multiple AI models. Felo OpenAPI takes that concept further by adding tool APIs, memory, and output capabilities.

Here's a detailed comparison.

What Each Platform Does​

OpenRouter​

OpenRouter aggregates multiple AI model providers into a single API:

  • Access to models from OpenAI, Anthropic, Google, and others
  • Unified API interface
  • Model routing and failover
  • Pay-per-use pricing

What it does well: Model aggregation, routing, and cost comparison across providers.

What it doesn't do: Tool APIs, memory, output generation. It's models only.

Felo OpenAPI​

Felo OpenAPI provides the full agent capability stack:

  • Model APIs — Claude Opus 4.8, Claude Sonnet 4.6, Claude Haiku 4.5, GPT-5.6 Sol, GPT-5.6 Terra, Grok 4.5
  • Tool APIs — Search, Web Fetch, X Search, YouTube Subtitles
  • Output APIs — PPT, Mindmap, Landing Page, Image Generation
  • Memory — LiveDocs with semantic retrieval
  • Workflows — SuperAgent for multi-step conversations

What it does well: Complete agent platform — models, tools, memory, and output under one key.

What it doesn't do: Model routing and automatic failover (yet).

When to Use OpenRouter​

OpenRouter makes sense when:

  • You only need model access, not tools or output
  • You want automatic model routing and failover
  • You're building custom tool integrations separately
  • You need the widest possible model selection

When to Use Felo OpenAPI​

Felo OpenAPI makes sense when:

  • Your agent needs more than models — it needs search, memory, and output
  • You want one key for everything, not models plus separate tool subscriptions
  • You need PPT generation, landing pages, mindmaps, or image creation
  • You want persistent memory (LiveDocs) for team workflows
  • You're running agents that chain tools together in workflows

Cost Comparison​

Both platforms offer competitive model pricing. The real difference comes when you factor in tools:

With OpenRouter:

  • Model API costs through OpenRouter
  • Separate search API subscription (SerpAPI, Tavily, etc.)
  • Separate memory/database solution
  • Separate output tools (PPT, image generation)
  • Multiple accounts, keys, and billing

With Felo OpenAPI:

  • Model API costs through Felo (comparable or lower)
  • Search, extraction, social data included
  • LiveDocs memory included
  • PPT, mindmap, landing page, image APIs included
  • One account, one key, one bill

For agents that use tools (which is most of them), Felo OpenAPI is more cost-effective because you're not paying for separate services.

The Missing Piece in Model-Only Platforms​

OpenRouter solves the model access problem. But agents don't just need models — they need:

  • Fresh data — models alone can't search the live web
  • Memory — models don't remember between sessions
  • Output — models produce text, not slide decks or landing pages
  • Social signals — models can't access X or YouTube data

Felo OpenAPI fills these gaps. OpenRouter doesn't.

Getting Started​

  1. Create your free API key
  2. Browse available models
  3. Explore the full tool stack

If your agent only needs models, OpenRouter works. If it needs to actually finish work, try Felo OpenAPI.
