# Pool Payout vs Expected Reward — Adjacent Period Changes

> Pool Payout vs Expected Reward — Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes period-over-period changes in the deviation between actual Bitcoin pool payouts and expected mining rewards across a series of rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pool-payout-vs-expected-reward-adjacent-period-changes-b7642f67 -d '<json body>'
```

Example prompt: I have 4 consecutive mining periods with these received and expected BTC amounts: period 1 got 0.011 vs expected 0.01, period 2 got 0.0121 vs expected 0.011, period 3 got 0.011 vs expected 0.01, period 4 got 0.0121 vs expected 0.011 — can you calculate how the pool payout deviation changed between each adjacent period?

## When to prefer this

Choose this endpoint when you need to specifically analyze how the gap between actual pool payouts and expected mining rewards evolves across consecutive time periods — i.e. adjacent period change analysis — rather than a static snapshot or aggregate summary. It is best suited for sequential mining data where trend direction and period-to-period shifts in payout deviation matter, not just overall averages.

## Known failure modes

- Fewer than 2 rows supplied (minItems:2 violated) — request rejected
- received_btc or expected_btc is zero or negative (exclusiveMinimum:0) — validation error
- More than 200 rows supplied (maxItems:200 exceeded) — request rejected
- Missing required fields received_btc or expected_btc on any row — validation error
- Service unavailable or payment not processed — 402/5xx response

## How this service works

Pool payout versus expected reward — Adjacent period changes: Adjacent period changes for Pool payout versus expected reward. Supplied mining assumptions only; formula and units disclosed. No live prices, mining or guaranteed return. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded adjacent period changes report.

## Output

A bounded report showing the adjacent period changes in the deviation between received and expected BTC payouts for each consecutive pair of supplied mining periods, based solely on the user-supplied assumptions and disclosed formula — no live prices or guaranteed return figures included.
