# Synapse API — Tron RPC Endpoint

> Synapse API — Tron 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 2026-09-13).

Proxies JSON-RPC method calls to the Tron blockchain network, enabling read and write interactions with on-chain data.

## Facts

- Endpoint: POST https://synapse-api-brown.vercel.app/api/tron/rpc
- Price: $0.01/call
- Payment: x402
- Status: unknown

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-tron-rpc-endpoint-0e9a0509 -d '<json body>'
```

Example prompt: Can you call the Tron RPC endpoint with method 'eth_getBalance' and params ['TJYQnSAAn7hqfzMEJBLVEDhCkMaSSxz9Kp', 'latest'] to fetch that wallet's current TRX balance?

## When to prefer this

Choose this endpoint when you need pay-per-call access to the Tron blockchain without running your own node or managing node infrastructure. Ideal for agents that need occasional Tron RPC calls (balance lookups, transaction broadcasts, contract reads) and want micro-payment billing via x402 rather than a monthly subscription. Prefer over self-hosted nodes when cost per call ($0.01 USDC) is acceptable and operational simplicity is a priority.

## Known failure modes

- Invalid RPC method name returns error code -32601 Method not found
- Malformed params array causes -32602 Invalid params error
- Payment not received or x402 auth failure returns 402 Payment Required
- Network congestion or Tron node unavailability causes timeout or 503
- Broadcasting invalid or unsigned transactions returns on-chain rejection error
- Rate limiting may apply if called excessively in short succession

## 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

Returns a standard JSON-RPC response object containing the result field with on-chain data (block info, balances, transaction receipts, contract outputs, etc.) or an error object with code and message if the call fails.
