How this service works
Pay-per-call machine services settled in USDC on Base via x402. No human in the loop; settlement is verified on-chain.
Output
Returns a JSON object with an 'ok' boolean, a 'watch_id' string echoing the requested feed name, and an 'items' array containing the most recent monitoring events or data points up to the specified limit.
Example use cases
Crypto funding rate surveillance
“Check the VIVARIUM monitor for the latest 20 funding rate entries using watch ID 'funding_rates' — I want to see what's moved recently.”
Autonomous agent event polling
“Poll my VIVARIUM watch feed with ID 'eth_liquidations' and get the last 5 items so my trading bot can react to new liquidation events.”
Paginated feed catchup
“Fetch up to 50 items from the VIVARIUM monitor channel 'perp_open_interest' — I need to catch up on everything that's happened since my last check.”

Endpoint
POSThttps://vivarium-gateway.masterfree818.workers.dev/svc/monitor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call polling of a named monitoring feed (such as crypto funding rates) without standing up persistent infrastructure. It is ideal for autonomous agents that only need data on demand and want costs tied directly to usage, settled on-chain in USDC via x402.
Side effects
- Unknown or invalid watch_id returns an empty items array or error
- Payment failure (insufficient USDC balance) results in 402 response before data is returned
- limit parameter out of range may return no items or a validation error
- Cloudflare Worker timeout if upstream data source is slow
- Network errors to workers.dev edge may cause transient 5xx responses
