- The name "get_agent_rails_index" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns a versioned, source-cited index of rails on which an autonomous agent can attempt to earn, with the payer, settlement channel, prerequisite gate and our own verification status per entry. The index itself is paid: this tool returns the x402 payment requirements for the resource that serves it.
```
