# Vextorium Hedera Network Data

> Vextorium Hedera Network Data is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-19).

Returns real-time Hedera network stats including HBAR total and circulating supply, last block number, transaction count, market price in USD, and current/next exchange rates.

## Facts

- Endpoint: POST https://api.vextorium.com/v1/hedera-network?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-19
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/vextorium-hedera-network-data-2743c6bc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_lnrAoUDSI2rltEVZ_k2pj

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 vextorium-hedera-network-data-2743c6bc -d '<json body>'
```

Example prompt: What is the current HBAR price in USD, the circulating supply, and how many transactions were in the last Hedera block?

## When to prefer this

Use this endpoint when you need a quick, all-in-one snapshot of the Hedera network: HBAR supply metrics, current block, transaction throughput, and live USD price/exchange rate in a single call. Prefer over manually querying Hedera Mirror Node directly (no auth setup) or scraping DefiLlama separately. Best for agents needing HBAR market context or on-chain health checks at minimal cost ($0.002/call).

## Known failure modes

- Hedera Mirror Node unavailable — service may return stale or error response
- DefiLlama market price feed down — market_price_usd may be null
- Network congestion causing delayed block data
- x402 payment failure — request rejected without USDC payment
- Malformed POST body — ensure bodyType matches payload format

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing HBAR total supply (50B), circulating supply (~44B), last block number, transaction count in last block, current and next USD/HBAR exchange rates, market price in USD sourced from DefiLlama, and a valid_until timestamp indicating data freshness.
