# Discovery Tools

These tools help the agent find services and move the user into the right hosted flow.

## `search_bazaar`

Use this tool to discover x402-gated services.

Typical cases:

* find a paid API
* look up a service before payment
* choose the right target before invoking `pay` or `x402_fetch`

## `open_onramp`

Use this tool to launch the hosted on-ramp flow.

Typical cases:

* the user needs to add money
* the wallet is empty
* the flow should leave Claude and continue in a browser

## Why these matter

Discovery tools keep the agent from guessing.
They turn the wallet into a guided workflow rather than a blind payment button.
