# Chains and prices

> Every chain Lasso Cloud's managed pool serves and the USD price of each method by routing strategy, generated from agent.json

# Chains and prices

These tables are generated from the live
[`agent.json`](https://lasso.sh/agent.json), so they match what Lasso serves
and charges. When you need a value at runtime, read `agent.json` directly.

```bash theme={null}
curl -fsSL https://lasso.sh/agent.json | jq '.chains, .pricing'
```

## Chains

Use the name or the chain ID as the `<chain>` segment of an RPC URL. Your
Custom profiles can serve any EVM chain your providers serve.

| Chain name | Chain ID |
| - | - |
| `ethereum` | 1 |
| `optimism` | 10 |
| `bsc` | 56 |
| `unichain` | 130 |
| `polygon` | 137 |
| `world` | 480 |
| `tempo` | 4217 |
| `robinhood` | 4663 |
| `base` | 8453 |
| `arbitrum` | 42161 |
| `tempo-testnet` | 42431 |
| `base-sepolia` | 84532 |
| `arbitrum-sepolia` | 421614 |
| `ethereum-sepolia` | 11155111 |

## Request prices

The USD price of one request on premium providers, by method and strategy.
Requests served on public providers or Custom profiles have no request price.
A batch is priced per item, and each WebSocket subscription notification is
priced as an `eth_subscription` request.

## Limits

* A method's presence here is its price, not a promise that every provider in
  the pool serves it. See [RPC method behavior](/cloud/rpc-behavior).
* Prices can change; a purchase is always held to the terms in the challenge
  you signed.

## Next

* [Serving access and pricing](/cloud/serving-access-and-pricing): how prices,
  included usage and free access fit together.
* [Balance and payment fallback](/cloud/balance-and-fallback): paying for
  requests.
