Model APIs are only the first layer. The real upgrade starts when your Agent can call tools.
Use the Agent you already like.
Plug Felo OpenAPI into OpenClaw, Claude Code, Codex, Hermes Agent, scripts, or your own runtime.
Run stronger models for less.
Lower model cost means more testing, longer workflows, and fewer compromises when your Agent needs serious reasoning.
Stop stitching model providers together.
Use one API key instead of managing scattered accounts, keys, limits, and billing across providers.
Give your Agent a whole shelf of superpowers.
One API key unlocks the things modern Agents actually need: live search, web extraction, X data, YouTube transcripts, PPT generation, mindmaps, LiveDocs memory, image creation, landing pages, SuperAgent workflows, and more.
Explore all harness APIsGive your Agent the missing stack.
Your Agent may already think and plan. Felo adds models, fresh context, memory, and output capabilities so it can actually finish work.

Codex
Let Codex connect to low-cost LLM APIs and callable tools for research, content, office workflows, and deliverables.
OpenClaw, Hermes Agent, and custom agents
Add Felo OpenAPI as the missing tool layer for search, X data, extraction, LiveDocs, PPTs, images, and more.
Your Agent keeps the thinking loop. Felo adds model APIs, tool APIs, memory, and office output abilities.
More than endpoints. A one-key Agent upgrade.
Use only the APIs you need today. Add more tools as your Agent grows from usable to seriously useful.

Open setup checklistNeed Search, PPT, LiveDocs, or more?
One Felo key works across Felo APIs. Connecting a model provider does not automatically install Search, PPT, LiveDocs, or other Harness tools.
From prompt to office deliverable.
Ask for the outcome. Let your Agent call the tools for research, context, memory, and output.
Market research to presentation
Search API > Web Fetch > X Search > LiveDocs > PPT API
Gather sources, preserve evidence, and generate a deck your team can review.
Launch idea to campaign package
Prompt > Search > Web Fetch > Image API > Landing Page API
Turn a product idea into research, visuals, page structure, copy, and campaign materials.
Files and URLs to office output
Upload files > LiveDocs Retrieve > PPT API > Mindmap API
Convert documents and URLs into slides, mindmaps, briefs, and reusable knowledge.

Let your favorite Agent call model APIs and tool APIs from the same capability layer.
FAQ
Clear answers for people connecting Felo API to Claude Code, Codex, OpenClaw, Hermes Agent, scripts, or their own Agent runtime.
Is Felo OpenAPI only for developers?
+
No. Felo OpenAPI is especially useful for people using OpenClaw, Claude Code, Codex, Hermes Agent, and similar Agent tools that can connect third-party APIs.
Can I use it with Claude Code, Codex, or OpenClaw?
+
Yes. Felo OpenAPI supports model protocols and tool APIs that can be connected to Claude Code, Codex, OpenClaw, Hermes Agent, scripts, and custom agents.
What does Felo add to my Agent?
+
Felo gives your Agent model APIs, fresh information, memory, and output capabilities through web search, page extraction, X data, YouTube subtitles, PPTs, mindmaps, images, landing pages, and LiveDocs.
Why use one Felo key instead of separate tools?
+
Because the Agent gets a coherent stack through one entry point: LLM APIs to run, tool APIs to gather context, LiveDocs to remember, and output APIs to deliver.
One API key. Upgrade the whole Agent.
Start free with one Felo OpenAPI key. Connect low-cost LLM APIs, search, X, extraction, creation APIs, and LiveDocs to the Agent workflows you already use.
Stop wiring random tools one by one. Give your Agent the stack it needs to actually finish work.
