# x402 Facilitator Health Oracle

> x402 Facilitator Health Oracle is a paid API for AI agents from home.chrz.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Checks the health and capabilities of x402 payment facilitators on Solana mainnet, returning latency and supported payment networks for each.

## Facts

- Endpoint: POST https://home.chrz.dev/agent-dust/v1/agent/x402-facilitators
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/x402-facilitator-health-oracle-26c71968
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_h7uamxOhIdBe-PlapDCwK

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 x402-facilitator-health-oracle-26c71968 -d '<json body>'
```

Example prompt: Before making my x402 paid API call, check which facilitators are currently healthy and support Solana exact payments, and tell me their latency numbers.

## When to prefer this

Use this endpoint when an AI agent needs to perform a preflight check before routing an x402-paid request on Solana or Base, and wants to know which facilitators are live, their latency, and which payment networks they support. Prefer this over hardcoding a facilitator URL or retrying blindly on failure.

## Known failure modes

- All facilitators may return ok:false if the network is degraded
- High latency readings may indicate facilitator overload
- The endpoint itself costs $0.01 USDC via x402 so the agent must have a funded wallet to call it
- Stale checked_at timestamps may indicate cached or slow oracle responses
- Network timeout if home.chrz.dev is unreachable

## How this service works

x402-paid Solana mainnet wallet preflight oracle for agents.

## Output

Returns a JSON object with ok status, a checked_at Unix timestamp, and an array of facilitator objects each containing an id, ok boolean, url, latency_ms, supports_base_exact, and supports_solana_exact flags — giving a live snapshot of the x402 facilitator network's health and capabilities.
