# agentbit.app Stablecoin Market Data

> agentbit.app Stablecoin Market Data is a paid API for AI agents from agentbit.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns ranked stablecoin market data including current price, peg deviation, circulating supply, peg mechanism, and supported chains — with optional filtering by symbol or depeg threshold.

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 agentbit-app-stablecoin-market-data-14c63785 -d '<json body>'
```

Example prompt: Show me the top 20 stablecoins ranked by market cap, including their current price and peg deviation — and flag any that are depegged by more than 0.5%.

## When to prefer this

Choose this endpoint when you need structured, agent-ready stablecoin market data — especially peg deviation — without building a DefiLlama integration yourself. Ideal for depeg screening, portfolio monitoring, or quickly checking a specific stablecoin's health. Prefer over raw DefiLlama API when you need a pre-normalized, filtered response with peg deviation already computed and ranked by market cap.

## Known failure modes

- Invalid limit value outside 1-50 range returns validation error
- Symbol filter returning zero results if substring doesn't match any tracked coin
- max_peg_deviation_percent filter returning empty set if no coins exceed the threshold
- Stale data if DefiLlama upstream is delayed (up to 10 minutes lag)
- Payment failure if insufficient USDC balance for x402 micropayment

## How this service works

Stablecoin market data with the number agents paying in USDC actually need: current price and PEG DEVIATION per coin, circulating supply, peg mechanism and chains, ranked by market cap. Filter by symbol or screen for depegs (absolute deviation above a threshold). Open DefiLlama data, refreshed every 10 minutes.

## Output

A JSON object containing an array of stablecoins each with name, symbol, current price, peg_deviation_percent (e.g. -0.02 means 2 cents below peg), circulating_usd, peg_type, peg_mechanism, and supported chains — plus result_count and universe_size metadata. Data is sourced from DefiLlama and refreshed every 10 minutes.
