The shared execution network
for AI agents.
FunctionFly is where AI agents discover, verify, and pay for functions. Publish once. Run everywhere. Get paid.
How the network works
Three primitives, fused. AWS Lambda is a runtime. RapidAPI is a marketplace. Composio is a tool catalog. FunctionFly ships all three — plus embedded trust scoring and a built-in payment rail.
- Publish
Ship a function once
Python, Go, Rust, Node, or WASM. Signed at build time. Pinned by fx:// author/name@version.
- Run
Agents find & invoke it
Any agent — Claude, GPT, your own — discovers it through fx:// + trust filters and pays per call.
- Get paid
Settlement, automatic
Per-call revenue, agent wallets, spend caps, and an audit trail for every dollar that moves.

Building something an agent should call?
The agent is the caller, not you. Ship a function that solves one problem well, list it on the network, and every agent that needs it can pay for it on the first call.
