## Verified on NoLimitNodes

| Feature | Status |
|---|---|
| `Subscribe` | Available |
| `Ping` | Available |
| `GetSlot` | Available |
| Account filters | Available |
| Transaction filters | Available |
| Slot filters | Available |
| Block and block metadata filters | Available |
| Entry filters | Available |
| Replay request fields | Plan dependent |

## SubscribeDeshred

`SubscribeDeshred` is not listed as a supported NoLimitNodes feature.

Do not build production logic around this method until your account team confirms endpoint support and limits.

Use standard `Subscribe` filters for accounts, transactions, slots, blocks, block metadata, and entries.

## Filter availability

The upstream proto evolves over time. Your selected server release and client release must agree on:

- Account data filters
- Transaction signature filters
- Block include flags
- Replay fields
- Ping messages
- Deshred request fields

## Verify before launch

Run one small request for every feature used by your application.

1. Call `Ping`.
2. Call `GetSlot`.
3. Open a single slot subscription.
4. Add your production filters.
5. Confirm message sizes.
6. Confirm your plan limits.
