One watcher, three prices, one rule: an agent watch that remembers its baseline

Description and use

An automated price watch that stores a baseline, applies a fixed rule, records every run, and provides verifiable receipts via Zambo.

Agents need a persistent baseline, non‑drifting thresholds, and proof that a watch ran on quiet days, but existing setups lack these features.

The watch runs once a day, costs 5 counted calls after the baseline, stays within the free tier, and provides a verifiable record of every run.

Add Zambo endpoint to an AI and set up a loop
Paste the no‑code instructions into the AI’s system prompt
On first pass: read the signal, save a baseline fact with receipts and rule text
On subsequent passes: recall baseline from memory, read the signal again, compute moves, apply rule, save reading, and wrap with a handover digest
Send the handover link to the operator for verification

A signal watch, in plain words, is one agent checking the same signal on a schedule: a price, a lead source, a mention feed, your own numbers.

The baseline is a remembered fact, and it carries three things: the values, the receipt of each reading they came from, and the rule in plain words.

The baseline pass cost 4 counted calls (3 prices and the baseline save); each check pass cost 5 (the recall, 3 prices, the reading save).

Pick any number in the digest, open its receipt, and check it at https://zambo.dev/verify/.
