# Token Assessment Evidence Coverage — Record Ranking

> Token Assessment Evidence Coverage — Record Ranking 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).

Ranks token assessment evidence coverage records by computing a deterministic coverage ratio (observed fields vs. requested fields) for each supplied row, returning ordered ranking results.

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-assessment-evidence-coverage-record-ranking-b8e3372a -d '<json body>'
```

Example prompt: Can you rank my token assessment evidence records by coverage? I have 4 rows: first has 8 observed out of 10 requested, second has 8.8 out of 11, third has 8 out of 10, and fourth has 8.8 out of 11.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, offline ranking of token assessment records by evidence coverage ratio without any live blockchain scanning, safety proofing, or trade recommendations. It is ideal for data quality workflows where you already have observed and requested field counts and simply need rows ranked by completeness. Prefer this over live token scanners when you want a reproducible, input-only computation at minimal cost ($0.01 USDC per call).

## Known failure modes

- Fewer than 2 rows supplied — minimum row count is 2, returns validation error
- More than 200 rows supplied — exceeds maxItems limit, returns error
- requested_fields set to 0 — exclusiveMinimum prevents zero, returns validation error
- Non-numeric values passed for observed_fields or requested_fields — schema validation failure
- Missing required fields observed_fields or requested_fields in any row — returns schema error

## How this service works

Token assessment evidence coverage — Record ranking: Record ranking for Token assessment evidence coverage. 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 record ranking report.

## Output

A ranked list of the submitted token assessment rows ordered by their evidence coverage ratio (observed_fields divided by requested_fields), produced via deterministic calculation. No live scan or external data fetch is performed — the result reflects only the supplied numeric values.
