# Maha Strategies Passage Hash Validation

> Maha Strategies Passage Hash Validation is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-20).

Validates exact UTF-8 SHA-256 hashes for up to 64 public or synthetic text passages without Unicode normalization or semantic processing.

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 maha-strategies-passage-hash-validation-6e618b6d -d '<json body>'
```

Example prompt: I have a batch of 12 synthetic text passages and I need to verify that their SHA-256 hashes are exactly correct — no Unicode normalization, just strict UTF-8 hash matching. Can you validate them for me?

## When to prefer this

Choose this endpoint when you need strict, exact UTF-8 SHA-256 hash validation for batches of text passages (up to 64) with no Unicode normalization, semantic interpretation, or source authentication — ideal for integrity checks on synthetic datasets or public text corpora where byte-exact hash fidelity is required.

## Known failure modes

- Passages array empty or exceeds 64 items — schema validation error
- dataClass not one of 'public' or 'synthetic' — enum rejection
- Malformed JSON body or wrong bodyType — request parse failure
- Hash mismatch detected — result flags the failing passages
- Payment insufficient or x402 challenge rejected — payment error

## How this service works

Validate exact UTF-8 SHA-256 hashes for up to 64 public or synthetic passages. No Unicode normalization, source authentication, or semantic validation.

## Output

Returns a structured result object containing the validation outcome per passage, an inputDigest and receiptDigest (SHA-256 identifiers for audit), the offerId ('passage-hash-validation'), version string, amount in base units (4000), and boundary markers indicating passage-level results — all without any semantic or normalization adjustments.
