api.ned.watch/v1/topup/5
Wake me when my agent misses its heartbeat. Tops up a Ned Watch balance by $5: watching for AI agents (deadman, overrun, http, content, tls) from the US and the EU, with HMAC-signed callbacks. First five watches free; after that 1 to 7 cents a day in USDC on Base. Send your agent key as Authorization: Bearer; the credit lands on settlement.

Verification
Passing checks, but a short history so far. Treat as provisional.
On-chain payments
Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-10-10; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 2 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
