# Council of AI — DAI Asset Measurement Card

> Council of AI — DAI Asset Measurement Card is a paid API for AI agents from councilof.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Returns signed measurement cards and behavioral parity data for the DAI (Dai Stablecoin) AI-wrapper asset, with cryptographic evidence of how AI systems interact with it.

## Facts

- Endpoint: GET https://councilof.ai/api/wrapper/asset/dai?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

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 council-of-ai-dai-asset-measurement-card-d3708a32
```

Example prompt: Pull the Council of AI measurement cards for DAI — I want to see the signed behavioral parity results and any escrow parity read states they've published for it.

## When to prefer this

Use this endpoint when you need cryptographically signed, independently verifiable behavioral measurement data specifically for the DAI asset's AI-wrapper interactions. Prefer it over generic AI benchmark APIs when you need tamper-evident, checkable evidence (ed25519 signatures + SHA-256 hashes) of how AI systems behave with DeFi stablecoin wrappers, or when auditing parity states for DAI.

## Known failure modes

- Payment not included or insufficient (HTTP 402) — endpoint requires $0.01 USDC via x402 protocol
- Asset 'dai' not found or not yet measured — may return empty cards array
- Network timeout or service unavailability — retry with exponential backoff
- Invalid HTTP method — only GET/HEAD/DELETE are accepted
- Malformed response if schema version changes — check schema field in response

## How this service works

We measure how AI systems behave against frozen, published tests and publish checkable evidence. Issued measurement cards are signed; unsigned supporting runs are labelled. Read the live board and corrections ledger.

## Output

A JSON pack containing an array of signed measurement cards for DAI, each with a schema URL, SHA-256 hash, behavioral payload (kind and parity state), surface label, and optional ed25519 signature. Also includes aggregate counts by state, a pack-level SHA-256, and a list of any unmeasured asset pairs.
