# Astrology Experiment Plan Checker

> Astrology Experiment Plan Checker is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.0485/call, status unknown (last checked 2026-10-20).

Validates a structured astrology or low-stakes experiment plan for timing, comparator, outcome, and analysis declarations, returning deficiencies and an integrity receipt.

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 astrology-experiment-plan-checker-e8e0d5dd -d '<json body>'
```

Example prompt: Check this astrology experiment plan for me: predictor is 'mars-ingress-aries', outcome is 'task-completion-rate', direction is 'higher', comparator is 'randomized-control', activity is 'synthetic-task', data class is 'public', sample size 200, assessed at 2024-06-01T00:00:00Z, running from 2024-06-10T00:00:00Z to 2024-06-30T00:00:00Z — flag any deficiencies and give me an integrity receipt.

## When to prefer this

Choose this endpoint when you need a lightweight, structured integrity check on a low-stakes astrology or synthetic experiment plan — specifically to detect declaration deficiencies and obtain a tamper-evident receipt digest. It is not a substitute for scientific peer review, power analysis, or pre-registration; use it for auditability of small public or synthetic experiments within the mahastrategies micro-product ecosystem.

## Known failure modes

- Missing required fields (dataClass, predictorId, outcomeId, etc.) result in validation errors
- Invalid enum values for activity, direction, or comparator cause rejection
- UTC timestamps exceeding 24 characters or malformed ISO strings fail parsing
- Sample size outside 0–1,000,000 range is rejected
- additionalProperties in body object cause schema validation failure
- Payment not included or insufficient USDC amount results in 402 payment required

## How this service works

Check one structured public or synthetic low-stakes experiment plan for timing, comparator, outcome and analysis declarations. Returns deficiencies and an integrity receipt. No registration, trusted timestamp, prediction, power analysis or scientific validation.

## Output

Returns a structured response containing a list of detected deficiencies in the experiment plan (e.g. missing fields, invalid enum values, inconsistent timestamps), an integrity receipt with a receipt digest and input digest for auditability, offer ID, version, amount in base units, and any boundary annotations. No scientific validation or prediction is performed.
