# Stratalize Data Freshness Attestation

> Stratalize Data Freshness Attestation is a paid API for AI agents from www.stratalize.com, paid per call via x402, $1/call, status unknown (last checked 2026-09-14).

Returns a post-quantum signed attestation of the current version and as-of timestamp for OFAC, OIG LEIE, or SAM exclusion screening datasets, independently verifiable on-chain.

## 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 stratalize-data-freshness-attestation-bdf744c9
```

Example prompt: Can you get me a signed, verifiable attestation of the current OFAC dataset version from Stratalize so I can prove to our compliance examiner that our sanctions list is up to date?

## When to prefer this

Use this endpoint when a compliance workflow, examiner, or audit process requires a cryptographically signed, independently verifiable attestation that a specific sanctions or exclusion screening dataset (OFAC, OIG LEIE, or SAM) was current at a given point in time. Prefer this over manual dataset checks when you need a tamper-evident, post-quantum signed receipt that can be submitted as audit evidence or verified by a third party without trusting the caller's word.

## Known failure modes

- Invalid dataset enum value (must be one of: ofac, oig, sam) — returns 400 Bad Request
- Payment not provided or insufficient — returns 402 Payment Required (x402 protocol)
- Upstream dataset sync temporarily unavailable — may return 503 with retry-after header
- Network timeout or service outage — returns 5xx error

## How this service works

Stratalize — attested finance, legal, healthcare, and compliance intelligence. Signed, independently verifiable receipt on every call (trust.stratalize.com/verify). Use when an examiner or compliance workflow needs a post-quantum signed attestation of screening-list currency. Returns list_version and as-of metadata for synced OFAC, OIG LEIE, or SAM exclusion datasets — the same versions bound into screening responses. Input dataset: ofac, oig, or sam

## Output

A signed, post-quantum attestation containing the list_version identifier and as-of timestamp for the requested dataset (OFAC, OIG LEIE, or SAM), along with a verifiable receipt URL at trust.stratalize.com/verify that an examiner or automated compliance workflow can independently confirm.
