# Vextorium Stablecoin Detail

> Vextorium Stablecoin Detail is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Returns detailed information about a specific stablecoin: pegging mechanism, current USD price, on-peg status, total circulating supply, and per-chain supply breakdown — live from DefiLlama.

## Facts

- Endpoint: POST https://api.vextorium.com/estable-detalle-pago?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-01
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/vextorium-stablecoin-detail-1d460f63
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_vhx4OT3Wdl8CuI1UyfnPQ

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 vextorium-stablecoin-detail-1d460f63 -d '<json body>'
```

Example prompt: Can you pull up the details for USDC — I want to know its current price, whether it's on peg, what its pegging mechanism is, and how its circulating supply breaks down by chain?

## When to prefer this

Use this endpoint when you need comprehensive, live stablecoin-specific data in a single call — including peg status, mechanism type, price, and multi-chain supply breakdown — sourced from DefiLlama. Prefer it over generic token price endpoints when you specifically need stablecoin metadata like pegging mechanism or on-peg boolean status. Best suited for depeg monitoring, stablecoin research, or cross-chain supply audits for a known symbol like USDT, USDC, DAI, or USDe.

## Known failure modes

- Unknown or misspelled stablecoin symbol returns null or empty fields
- Stablecoin not tracked by DefiLlama returns no data
- Temporary DefiLlama data outage results in stale or unavailable response
- Missing required 'simbolo' field in request body causes validation error

## How this service works

Detail of one stablecoin: pegging mechanism (fiat-backed, crypto-backed, algorithmic), price, on-peg status, total circulating supply and its breakdown by chain. Live from DefiLlama.

## Output

Returns a JSON object containing: stablecoin symbol and full name, pegging mechanism label (fiat-backed, crypto-backed, algorithmic), current USD price, a boolean indicating whether it is currently on peg, total circulating supply in USD, and an array of per-chain objects each listing the chain name and its share of circulating supply in USD. May also include an optional note field.
