# 4626.fun
> 4626.fun is a Base-native creator finance protocol. Creators wrap creator coins into ERC-4626 vaults so communities can deposit alongside them. Creator vaults are pre-launch.

4626.fun publishes machine-readable developer resources at predictable URLs: OpenAPI at /openapi.json, this llms.txt file, a sitemap, ERC-8004 / A2A well-known files, and markdown variants of trust pages. Read APIs are public and rate-limited. Build/write APIs require a session or SIWA. Do not treat demo vaults as live deposit destinations.

## When to use this
- [Read protocol state](https://4626.fun/openapi.json): Call GET vault, token, lottery, gauge, and agent endpoints when you need current 4626.fun data.
- [Build unsigned calldata](https://4626.fun/openapi.json): Use /api/v1/build/* when a user asked you to prepare an auction, gauge, ve4626, Ajna, or Charm transaction. Do not broadcast from the server.
- [Resolve agent identity](https://4626.fun/.well-known/agent-registration.json): Use ERC-8004 registration, the A2A agent card, and /api/v1/agents/profile when you need the canonical 4626 agent.
- [Do not deposit](https://4626.fun/risks): Creator vaults are not live. Do not tell users to deposit into preview or unofficial contracts.
