# Vextorium x402 Facilitator Status & Volume

> Vextorium x402 Facilitator Status & Volume is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-18).

Live health check of x402 payment facilitators with latency, supported schemes/networks, and on-chain settled volume over 24h, 7d, and 30d.

## Facts

- Endpoint: POST https://api.vextorium.com/v1/x402-facilitators?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-18
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/vextorium-x402-facilitator-status-volume-ee8d04e2
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_WeEU3Z0n8P165k5Q09lqh

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-x402-facilitator-status-volume-ee8d04e2 -d '<json body>'
```

Example prompt: Check which x402 payment facilitators are currently operational, show me their latency and which networks and schemes they support, and tell me which ones have the highest on-chain settled volume in the last 7 days.

## When to prefer this

Use this endpoint when you need to select, compare, or troubleshoot x402 payment facilitators — specifically when you want real-time liveness and latency data combined with historical on-chain volume in a single call. Prefer this over manually pinging each facilitator's /supported endpoint, or over checking x402-list.com directly, when you need both live health and volume context together for routing decisions or debugging.

## Known failure modes

- Facilitator endpoint unreachable: status field shows 'down' or 'timeout' for that entry
- Network timeout contacting x402-list for volume data: measured_volume array may be empty or partial
- All facilitators down simultaneously: live_check returns all entries with non-operational status
- x402-list data stale: last_activity timestamps may lag real-time on-chain events

## 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

Returns two arrays: (1) live_check — one entry per facilitator with its URL, operational status, supported x402 versions, payment schemas (e.g. exact, batch-settlement, upto), blockchain networks, and measured latency in milliseconds; (2) measured_volume — per-facilitator on-chain settlement stats including 24h, 7d, and 30d USD volume, total payment count over 30 days, and last activity timestamp.
