## 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-latest-block-8dbd68fa -d '<json body>'
```

Example prompt: What's the latest block on the TRON blockchain right now — give me the block number, hash, and timestamp?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call access to the TRON blockchain's latest block without managing your own node infrastructure. Ideal for agents that need occasional or infrequent TRON chain queries without committing to a subscription. Prefer alternatives if you need historical block data, batch queries, or very high-frequency polling.

## Known failure modes

- TRON node unavailable or rate-limited — may return 5xx error
- Network congestion causing stale or delayed block data
- Payment failure via x402 protocol resulting in 402 Payment Required
- Malformed request body returning 400 Bad Request
- Vercel cold start latency causing timeout on first call
