# ADH DeFi Stablecoins Intelligence Layer

> ADH DeFi Stablecoins Intelligence Layer is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns real-time stablecoin market data including prices, circulating supply, peg type, backing mechanism, and chain distribution across the tracked stablecoin universe, sourced from DeFiLlama and normalized with entity resolution.

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 adh-defi-stablecoins-intelligence-layer-8ce28d03
```

Example prompt: Pull the latest stablecoin intelligence from ADH — I want to see current prices, circulating supply, peg types, and chain distribution for the tracked universe so I can assess peg stability across the DeFi market.

## When to prefer this

Choose this endpoint when you need a pre-normalized, agent-ready stablecoin dataset aggregated from DeFiLlama without needing to call DeFiLlama directly or handle entity resolution yourself. It is especially useful when building AI agents that need stablecoin context injected into their reasoning (macro regime analysis, crypto due diligence, peg monitoring) and want provenance metadata alongside the data. Prefer it over raw DeFiLlama calls when you want time-synchronized, sourced intelligence rather than raw API output.

## Known failure modes

- Upstream DeFiLlama API unavailability causing stale or missing data
- x402 payment failure if USDC balance is insufficient or wallet not configured
- Response may include duplicate chain entries per token (observed in example schema)
- Data freshness lag if collection pipeline is delayed
- Empty or partial dataset if fewer than expected stablecoins are tracked

## Output

A JSON object containing: an array of stablecoin records (each with name, symbol, price, chains, peg_type, peg_mechanism, circulating_usd), total tracked count, universe size, total circulating USD across all stablecoins, the underlying data source (DeFiLlama), data type label, and ISO 8601 collection timestamp. The response is pre-normalized with entity resolution and provenance metadata applied by the ADH intelligence layer.
