> Citation Binding Check is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.016002/call, status unknown (last checked 2026-10-15).

Validates citation metadata integrity by comparing up to 20 declared source identities, revisions, and locators against declared values, returning exact mismatches and an integrity receipt.

## 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 citation-binding-check-4aac5fa1 -d '<json body>'
```

Example prompt: Before I submit this evidence review, check these 5 citation bindings for mismatches — they're public data — and give me an integrity receipt showing any discrepancies in source identities, revisions, or locators.

## When to prefer this

Use this endpoint when you need a lightweight, structural check on citation binding metadata prior to an evidence review — specifically to detect identity, revision, or locator mismatches across up to 20 sources. Choose this over general citation tools when you need a machine-verifiable integrity receipt, not passage retrieval, claim verification, or source content access. Ideal for pre-submission pipeline steps in systematic reviews or agentic research workflows.

## Known failure modes

- More than 20 bindings submitted — returns validation error
- Missing required 'bindings' array — returns schema error
- Invalid 'dataClass' value outside 'public' or 'synthetic' enum — returns validation error
- Malformed binding objects — returns parse or schema error
- Expired result recovery window (after 24 hours) — result no longer retrievable

## How this service works

Check citation metadata before an evidence review. Compare up to 20 declared source identities, revisions and locators; return exact mismatches and an integrity receipt. No source retrieval, passage-existence check or claim-support verification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

## Output

Returns an integrity receipt listing exact mismatches found across the submitted citation bindings, including which source identities, revisions, or locators deviate from declared values. Receipt metadata is retained for 90 days; full results are available for 24 hours.
