# Mahastrategies Governed Context Verification Pack

> Mahastrategies Governed Context Verification Pack is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Builds an inspectable evidence pack from caller-supplied documents and labelled spans, combining token-budget comparisons, retention checks, and policy-bound receipts to verify declared context-selection workflows.

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 mahastrategies-governed-context-verification-pack-29c31403 -d '<json body>'
```

Example prompt: Run a governed verification pack on these 3 documents for the task 'summarize key risk factors', with a token budget of 4000, required evidence labels ['risk_factor','mitigation','timeline'], scoring by bm25, provenance set to full, and request ID 'audit-run-20240601-001'.

## When to prefer this

Choose this endpoint when you need an auditable, policy-governed verification trail for a context-selection or RAG pipeline run — specifically when you must prove that required evidence spans were present, token budgets were respected, and the workflow followed declared rules. Prefer it over generic document search or retrieval endpoints when compliance, auditability, and receipt-backed verification are requirements rather than nice-to-haves.

## Known failure modes

- Missing required fields (clientRequestId, task, tokenBudget, documents, requiredEvidence) returns a 400 validation error
- Token budget outside 64–16000 range causes rejection
- More than 8 documents or more than 32 required evidence labels exceeds schema limits and is rejected
- Invalid scoring enum value (not 'bm25' or 'keyword') causes a validation failure
- If required evidence labels are not found in the supplied documents, the deliverable may report unmet evidence with limitations listed
- Payment failure via x402 protocol returns a payment-required error before processing

## How this service works

Prepare an inspectable context-selection evidence pack from caller-supplied documents and labelled spans. Combines budget comparisons, retention checks and policy-bound receipts. Verification concerns the declared workflow, not factual truth, answer quality or legal compliance.

## Output

Returns a versioned deliverable object containing the compiled evidence pack, a receipt digest (cryptographic hash of the verification run), a list of limitations encountered, boolean flags indicating whether source text and compiled context were stored, the offer ID, and the client request ID — enabling full auditability of the context-selection workflow without retaining source text.
