How this service works
Pay-per-call machine services settled in USDC on Base via x402. No human in the loop.
Output
A JSON object with an 'ok' boolean, a 'watch_id' string echoing the requested feed, and an 'items' array containing the most recent monitored events or data points (up to the requested limit) for that watch stream.
Example use cases
Funding rate drift alert
“Check the funding_rates watch feed on VIVARIUM and give me the last 10 items — I want to know if anything has spiked recently.”
Autonomous agent status polling
“Poll my VIVARIUM monitor with watch ID 'liquidations_watch' and fetch the 50 most recent items so my agent can react to any new liquidation events.”
Periodic market data harvest
“Retrieve the latest 25 items from the funding_rates monitor feed so I can log them to my database as part of my hourly data pipeline.”
Technical details
Endpoint
POSThttps://api.altahub.net/svc/monitor?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need autonomous, pay-per-call polling of a named monitoring feed (e.g. funding rates) without any human intermediary, and you want settlement in USDC on Base via x402. Prefer this over traditional REST monitoring APIs when operating in a crypto-native agent stack that already handles x402 micropayments.
Side effects
- Unknown or invalid watch_id returns empty items array or error
- Limit exceeding backend cap may be silently clamped or return an error
- Payment failure (insufficient USDC balance) blocks the call with a 402 response
- Network timeout if the autonomous service pipeline is unavailable
- Malformed request body (missing watch_id) likely returns a 400-level error
