# Token Transfer Receipt Fraction — Adjacent Period Changes

> Token Transfer Receipt Fraction — 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 2026-10-12).

Computes period-over-period changes in the token transfer receipt fraction (received/sent ratio) across a sequence of token transfer observations.

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 token-transfer-receipt-fraction-adjacent-period-changes-16bb4dac -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in token transfer receipt fraction for these four transfer records: period 1 sent 1000 received 990, period 2 sent 1100 received 1089, period 3 sent 1000 received 990, period 4 sent 1100 received 1089?

## When to prefer this

Choose this endpoint when you need a deterministic, bounded computation of how the token receipt fraction (received/sent) shifts between consecutive observation periods, using only your supplied data. Prefer it over general analytics tools when you want a focused, low-cost ($0.01 USDC) period-change report without live blockchain scanning or predictive modeling.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 observations required
- sent_tokens value of 0 or missing — division by zero not permitted (exclusiveMinimum enforced)
- received_tokens or sent_tokens exceeds maximum of 10,000,000,000,000,000
- More than 200 rows submitted — maxItems constraint violated
- Malformed JSON or missing required fields result in validation error
- Payment of 0.01 USDC not fulfilled — x402 payment required error

## How this service works

Token transfer receipt fraction — Adjacent period changes: Adjacent period changes for Token transfer receipt fraction. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. 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 token transfer receipt fraction (received_tokens / sent_tokens) for each consecutive pair of input rows. Returns deterministic deltas computed from the supplied observations — not a live scan or safety assessment. One report per call, covering up to 200 rows.
