# Biology Assays - Condition Coverage Map

> Biology Assays - Condition Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035144/call, status unknown (last checked 2026-10-20).

Validates that each required control in a biology assay run has exactly one satisfied control declaration, flagging missing, unknown, duplicate, or wrong-frame controls.

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 biology-assays-condition-coverage-map-6af6f8b6 -d '<json body>'
```

Example prompt: Check the condition coverage for assay run 'RUN-2024-0042' using method digest 'abc123def456', revision 'v3', with required controls ['positive-ctrl','negative-ctrl','blank'] and the following declared controls — tell me if any are missing, duplicated, or wrong-frame. Use public data class.

## When to prefer this

Choose this endpoint when you need to programmatically audit biology assay records for control completeness against a strict exactly-one-satisfied-declaration rule, particularly when checking a specific run/method/revision combination. It is purpose-built for assay quality control validation workflows rather than general-purpose data comparison or independent lab certification.

## Known failure modes

- Missing required controls — one or more required controls have no matching declaration, causing a coverage failure
- Duplicate controls — a required control appears more than once, failing the exactly-one constraint
- Wrong-frame controls — a control declaration exists but does not match the expected run/method/revision frame
- Unknown controls — declared controls cannot be identified or resolved against the required list
- Invalid or missing runRef — the run reference does not match any known record
- Empty requiredControls array — at least one required control must be specified (minItems: 1)
- Controls array exceeds maxItems:32 or requiredControls exceeds maxItems:16 — input rejected
- nonpersonalMetadata not set to true — required constant field missing

## How this service works

Require exactly one satisfied control declaration for each required control in an exact run/method/revision; missing, unknown, duplicate or wrong-frame controls cannot pass for assay measurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a condition coverage map showing which required controls are satisfied, missing, unknown, duplicated, or wrong-frame for the specified assay run, method digest, and revision. Highlights exactly which controls fail the single-satisfied-declaration requirement and why.
