### Why agents use Vaults.fyi

{% hint style="success" %}
AI agents need reliable, structured data and executable transactions to operate autonomously in DeFi. Vaults.fyi is a full suite to discover, evaluate, execute, and manage a yield portfolio — all through a single API.
{% endhint %}

* [x] **x402 protocol support** — no API key required, pay-per-request with stablecoins
* [x] **Single API, no protocol-specific logic** — agents don't need to understand dozens of contract interfaces
* [x] **Ready-to-sign transaction payloads** — agents can prepare and execute deposits and withdrawals without custom contract logic
* [x] **Reputation scores and benchmarks** — programmatically assess risk and compare yields before acting
* [x] **Advanced protocol handling** — deferred deposits and delayed withdrawals out of the box
* [x] **Reward claiming** — access to claim reward actions across providers rewards distribution providers, including Merkl
* [x] **Portfolio management endpoints** — track positions, idle assets, and PnL to inform rebalancing decisions
