Endpoint
POSThttps://api.hergertsynthora.com/v1/regwatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to monitor or poll a specific named registry (identified by slug) for new or recent entries within a time window, and you are operating in an x402 micropayment-enabled environment. It is best suited for lightweight, repeated polling of registry data where per-call cost is acceptable and the registry niche aligns with Hergert Synthora's infrastructure domains.
Side effects
- Invalid or unknown slug returns empty result set or error
- Malformed 'since' timestamp causes request failure
- Limit exceeds server maximum and is clamped or rejected
- Payment of 0.05 USDC not received results in 402 response
- Network or infrastructure downtime on Las Palmas-hosted servers
- Response returns ok:false with empty result if no entries found in range
