# PulseScanner PulseChain JSON-RPC

> PulseScanner PulseChain JSON-RPC is a paid API for AI agents from x402.pulsescanner.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-21).

Executes JSON-RPC 2.0 calls (single or batch up to 10) against the PulseChain (chain ID 369) EVM node

## Facts

- Endpoint: POST https://x402.pulsescanner.io/rpc?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21

- Tags: x402
- Canonical page: https://www.zero.xyz/c/pulsescanner-pulsechain-json-rpc-afe051e5
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_BKYwn-avwvRi1UmS0v7nJ

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 pulsescanner-pulsechain-json-rpc-afe051e5 -d '<json body>'
```

Example prompt: Send a JSON-RPC call to PulseChain (chain ID 369) using eth_getBlockByNumber to get the latest block with full transaction details.

## When to prefer this

Choose this endpoint when you need direct EVM JSON-RPC access to PulseChain (chain ID 369) specifically, including light read methods or heavier calls like eth_getLogs and block fetches, with transparent per-CU pricing and batch support. Prefer it over generic EVM RPC providers when you want a pay-per-use metered PulseChain node without a subscription, or when batching multiple read calls in a single round trip.

## Known failure modes

- eth_sendRawTransaction not supported — returns error if attempted
- Batch exceeds 10 entries — rejected
- Invalid JSON-RPC method or params — returns JSON-RPC error object
- Network or node unavailability — HTTP 5xx or timeout
- Payment failure via x402 — request not processed
- Requesting non-existent block hash or number — null result returned (not charged)

## How this service works

PulseChain (chain id 369) JSON-RPC 2.0, one call or a batch of up to 10. $0.001 per request plus $0.002 per CU: light methods 2 CU ($0.005), eth_getBlockByHash, eth_getBlockByNumber and eth_getLogs 5 CU ($0.011). A batch is charged in full if any entry returns a result; an answer with no result is never charged. eth_sendRawTransaction is not sold.

## Output

A JSON-RPC 2.0 response object (or array of responses for batch calls) containing the result field with the requested on-chain data such as block objects, log arrays, balances, nonces, or call return values. Errors are returned in the JSON-RPC error field. No result means no charge.
