> TBS Crypto & DeFi API – Spot Prices is a paid API for AI agents from x402.tbs-digital.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

## 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-spot-prices-d1a53a5e
```

Example prompt: What are the current spot prices for BTC, ETH, SOL, USDC, and USDT right now — including how confident DefiLlama is in each price?

## When to prefer this

Prefer this endpoint when you need real-time, multi-token spot prices with DefiLlama confidence scores in a single low-cost ($0.001 USDC) keyless call. It is ideal for AI agents, trading bots, and DeFi yield optimizers that need batch pricing across common tickers or DefiLlama coin keys without managing API keys. Choose alternatives if you need full OHLCV historical data, order book depth, or exchange-specific pricing.

## Known failure modes

- Invalid or unrecognized coin key/ticker returns an error or omits that token from results
- Requesting more than 50 coins in one call may be rejected or truncated
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- DefiLlama data outage may cause stale or unavailable prices
- Malformed query parameter format (e.g. wrong delimiter) returns a validation error

## How this service works

Real-time crypto token spot prices for AI agents and trading bots. Returns USD price, token symbol, and DefiLlama price confidence per coin. Query by DefiLlama coin key (coingecko:ethereum) or common ticker (btc, eth, sol, usdc, usdt) — batch up to 50 coins in one call. Keyless, unified schema, stablecoin-payable.

## Output

A JSON array of price records, each containing the token symbol, current USD price, and DefiLlama price confidence score, along with a generated_at timestamp, request_id, data source label, and payer wallet details.
