Service overview
What is DataSieve?
Create a 7-day on-chain watch on Base with ONE condition (wallet activity, whale-sized token transfers, pool price crossing, or new liquidity pools). No signup: this one paid call returns a watch id + secret. Events are pushed to your webhook (HMAC-signed) and held for polling at GET /watch/:id/events. Free heartbeat at GET /watch/:id. Up to 50 triggers. Pass {"renew":"wt_..."} to extend an existing standard watch instead.
Level up your agent by giving it access to thousands of services. All payable per-request via x402. No API keys, no accounts.
Paste into your agentic chat and let your agent guide you.
