# NodeFlare Sei RPC (Chain 1329)

> NodeFlare Sei RPC (Chain 1329) is a paid API for AI agents from rpc.nodeflare.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Provides pay-per-request JSON-RPC access to the Sei blockchain (chain 1329) including archive, trace, and debug methods, paid in USDC via x402 protocol.

## Facts

- Endpoint: POST https://rpc.nodeflare.app/sei/x402
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nodeflare-sei-rpc-chain-1329-e0565bbd
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_KuCBqdZw--oMzcZBN8lUu

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 nodeflare-sei-rpc-chain-1329-e0565bbd -d '<json body>'
```

Example prompt: Can you call eth_getLogs on the Sei blockchain (chain 1329) to fetch all Transfer events from contract 0xABC...123 between blocks 5000000 and 5001000?

## When to prefer this

Choose this endpoint when you need permissionless, no-account RPC access to the Sei blockchain (chain 1329) and want to pay per call in USDC without managing API keys. Especially suitable for AI agents running autonomous workflows, indexing pipelines needing eth_getLogs or archive/trace/debug methods, or one-off smart contract simulations on Sei where subscription RPC plans are impractical.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601
- Malformed params array causes parse error -32700
- Insufficient USDC balance causes payment rejection before request is processed
- Requesting non-existent block or transaction returns null result
- Rate or compute-unit limit exceeded returns HTTP 402 or provider-specific error
- Archive methods unavailable on non-archive nodes return error -32000

## How this service works

Sei RPC (chain 1329): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units. One of the first independent x402 RPC providers for this chain.

## Output

A standard JSON-RPC 2.0 response object containing the result field with blockchain data (block info, logs, call return values, traces, etc.) or an error object with code and message if the call fails.
