# Pocket Network – Moonbeam (EVM/Polkadot) JSON-RPC

> Pocket Network – Moonbeam (EVM/Polkadot) JSON-RPC is a paid API for AI agents from agent.pocket.network, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-03).

Provides read-only Ethereum-compatible JSON-RPC access to Moonbeam, the EVM parachain on Polkadot, via Pocket Network's decentralised node infrastructure.

## Facts

- Endpoint: POST https://agent.pocket.network/v1/moonbeam?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-03
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/pocket-network-moonbeam-evm-polkadot-json-rpc-552717d5
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_VExpwmwJ6pnXf637fXVw7

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pocket-network-moonbeam-evm-polkadot-json-rpc-552717d5 -d '<json body>'
```

Example prompt: What's the current GLMR balance of the address 0xAbCd...1234 on Moonbeam? Use eth_getBalance and return the result in wei.

## When to prefer this

Choose this endpoint when you need read-only EVM JSON-RPC access specifically to the Moonbeam parachain on Polkadot, without wanting to manage API keys or accounts — pay-per-call in USDC via x402. Prefer it over self-hosted nodes when you want decentralised, censorship-resistant access backed by Pocket Network's supplier set. Not suitable for sending transactions or accessing non-EVM Polkadot chains.

## Known failure modes

- Invalid or unsupported JSON-RPC method returns an error object with code -32601
- Malformed params cause a -32602 invalid params error
- Block or transaction not found returns null result
- Payment not provided or insufficient USDC results in HTTP 402 rejection before processing
- Rate limits or node unavailability from the decentralised supplier set may cause intermittent timeouts
- Write methods (eth_sendRawTransaction) are not supported — this is a read-only endpoint

## How this service works

Read-only JSON-RPC access to Moonbeam, the EVM parachain on Polkadot, served by the Pocket Network decentralised supplier set. Pay per request in USDC; no account, no API key.

## Output

A standard Ethereum JSON-RPC response object containing a 'result' field (block data, balance in wei, transaction receipt, log array, hex-encoded values, etc.) or an 'error' object with code and message if the call fails. The exact shape depends on the method called.
