# Stablecoin List & Catalog

> Stablecoin List & Catalog is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Returns a ranked list of stablecoins with symbol, name, DefiLlama ID, peg type, collateral mechanism, circulating supply, price, and supported chains — optionally filtered by chain or collateral mechanism.

## Facts

- Endpoint: GET https://api.agentstools.dev/stablecoin/list
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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 stablecoin-list-catalog-34822b98
```

Example prompt: Show me the top 20 fiat-backed stablecoins on Base ranked by circulating supply — I need their symbols, DefiLlama IDs, and current prices.

## When to prefer this

Use this endpoint as the cheap first step to resolve a stablecoin symbol or name into the DefiLlama ID required by other api.agentstools.dev routes (peg check, risk profile, etc.). Also use it when you need a ranked overview of the stablecoin market, want to filter by chain or collateral mechanism, or need circulating supply and price data for multiple stablecoins in one call.

## Known failure modes

- Unknown chain name returns empty list or 400 error
- Invalid pegMechanism enum value returns 422 validation error
- limit out of range (< 1 or > 500) returns validation error
- DefiLlama feed temporarily unavailable causes 502/503
- No stablecoins match the combined filters, returning empty array

## How this service works

Catalog of covered stablecoins ranked by market cap, from the DefiLlama stablecoins feed. Each row carries symbol, name, DefiLlama id, peg type, collateral mechanism, total circulating supply, current price and the chains it lives on. Optionally filter by collateral mechanism or by chain. The cheap first step that resolves a symbol to the id the other routes use.

## Output

A ranked list of stablecoin records from DefiLlama, each containing: symbol, human-readable name, DefiLlama internal ID (used by sibling endpoints), peg type, collateral mechanism, total circulating supply, current price, and the list of chains where the stablecoin is deployed. Results are ordered by circulating supply descending and can be filtered to a specific chain or pegMechanism.
