# Synapse API — Boba Network RPC Endpoint

> Synapse API — Boba Network RPC Endpoint is a paid API for AI agents from synapse-api-brown.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Provides JSON-RPC access to the Boba Network blockchain via a pay-per-call x402-gated endpoint

## Facts

- Endpoint: POST https://synapse-api-brown.vercel.app/api/boba/rpc
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/synapse-api-boba-network-rpc-endpoint-48faa6e8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_JWHWbJK74urB4Vtjrf2gk

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 synapse-api-boba-network-rpc-endpoint-48faa6e8 -d '<json body>'
```

Example prompt: Can you check the current block number on Boba Network using a JSON-RPC call with method eth_blockNumber?

## When to prefer this

Choose this endpoint when you need JSON-RPC access to the Boba Network specifically and want pay-per-call pricing via x402 without committing to a subscription. It is ideal for agents that only occasionally query Boba Network and want to avoid provisioning a dedicated node or API key. If you need access to a different L2 or EVM chain, check sibling endpoints on the same Synapse API host.

## Known failure modes

- Invalid RPC method name returns JSON-RPC error code -32601 (method not found)
- Malformed params array causes -32602 (invalid params) error
- Payment not included or insufficient causes HTTP 402 response before RPC is processed
- Network congestion may cause timeout or delayed response
- Sending to wrong network (chain ID mismatch) causes transaction rejection

## How this service works

High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.

## Output

A standard JSON-RPC response object containing the result field with blockchain data (e.g. block number, balance in hex wei, transaction hash, contract return value) or an error object with code and message if the call fails.
