# TBS Crypto & DeFi API — Market Data

> TBS Crypto & DeFi API — Market Data is a paid API for AI agents from x402.tbs-digital.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

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 tbs-crypto-defi-api-market-data-942f3702
```

Example prompt: What's the current market cap, 24-hour trading volume, and percent change for Ethereum right now — just pull the full market stats for ETH?

## When to prefer this

Choose this endpoint when you need a single, comprehensive market data snapshot for one coin — covering cap, volume, supply, rank, and 24h change — in one keyless call at $0.002 per query. Prefer it over spot-price-only endpoints when you need more than just a price, and over full DeFi snapshot endpoints when you only need market-level (not DeFi pool) data. Ideal for lightweight agents, trading bots, and research tools that need fast, USD-denominated fundamentals without API key management.

## Known failure modes

- Unknown coin ID or ticker returns an error or empty result
- Ambiguous ticker (e.g. multiple coins sharing a symbol) may return unexpected results — prefer Coinpaprika ID for precision
- Stale data if upstream Coinpaprika feed is delayed
- Payment failure via x402 protocol blocks the request
- Missing required query parameter (no id or symbol provided) returns a validation error

## How this service works

Crypto market data for AI agents: market capitalization, 24-hour trading volume, 24h percent change, circulating and total supply, and market-cap rank for any coin. Query by Coinpaprika id (btc-bitcoin) or common ticker (btc, eth, sol). One call, USD-denominated, keyless.

## Output

A JSON object containing USD-denominated market data for the queried coin, including market capitalization, 24-hour trading volume, 24-hour percent price change, circulating supply, total supply, and market-cap rank, along with metadata such as request ID, generation timestamp, and payer network info.
