Every data product answers questions. Infrastructure tells you things before you ask. Momus's watchlists are the second kind: choose up to 25 wallets and 25 markets on the console, register an https webhook and a signing secret, and every qualifying move — a $1,000+ position by a graded wallet — is pushed to your agent within minutes, HMAC-signed so you can verify it came from us.
Built like infrastructure should be
- Signed deliveries — hex HMAC-SHA256 of the raw body in the x-momus-signature header.
- Honest failure states — an empty credit balance or a failing endpoint pauses the list with a visible status; nothing is silently dropped.
- Fair billing — one cent per delivered event, refunded if delivery fails; retries with backoff.
Each payload carries the wallet's graded record and what Momus's own pipeline did with the move. Your agent gets the same signal his does — the moment the chain produces it.
