# Source Packs - Declared-Bound Token Audit

> Source Packs - Declared-Bound Token Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010094/call, status unknown (last checked 2026-10-15).

Validates caller-declared token counts against per-source and total pack token ceilings without executing tokenization or packing

## 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 source-packs-declared-bound-token-audit-6ea56b24 -d '<json body>'
```

Example prompt: Can you audit my declared token counts against pack limits — I have 8 sources with public data, a per-source ceiling of 20000 tokens, and a total pack ceiling of 100000 tokens?

## When to prefer this

Use this endpoint when you need a fast, offline check that caller-declared token counts are within ceiling bounds before committing to context packing — without running a tokenizer or actually assembling the pack. Prefer this over full packing pipelines when you only need a budget pre-flight check on nonpersonal public or synthetic metadata. Ideal for pipeline validation steps that need a cheap, deterministic bound audit with an audit receipt.

## Known failure modes

- Sources array empty or exceeds 32 items — request rejected
- maximumPackTokens or maximumSourceTokens out of range (0–1,000,000) — validation error
- dataClass not one of 'public' or 'synthetic' — schema rejection
- nonpersonalMetadata not explicitly set to true — request rejected
- Malformed source entries — parsing error returned

## How this service works

Compare caller-declared token counts with per-source and total pack token ceilings. No tokenizer, packing execution or claim that all required evidence fits. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a comparison of each caller-declared source token count against the per-source ceiling and a comparison of the total declared tokens against the pack ceiling, identifying which sources or the aggregate exceed bounds. Includes a minimal receipt with metadata retained for 90 days; full result retained for 24 hours. No tokenization is executed; only declared values are compared.
