## 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 prysm-twelvedata-financial-market-data-provider-8b7e8476 -d '<json body>'
```

Example prompt: Pull the latest stock quote for AAPL using the TwelveData quote operation through Prysm — I need the current price, open, high, low, and volume.

## When to prefer this

Choose this endpoint when you need financial market data (quotes, OHLCV, technical indicators) from TwelveData and want to pay per-call in USDC via x402 on Base mainnet without managing a TwelveData API key directly. Ideal for AI agents in crypto-native or Web3 environments already using x402 micropayments.

## Known failure modes

- Invalid or unsupported operation name returns an error — only allowlisted TwelveData operations are permitted
- Malformed or missing ticker symbol causes TwelveData to return an error propagated in the response
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required and no data returned
- Rate limiting or upstream TwelveData API unavailability causes a timeout or 5xx error
- Requesting a symbol not covered by TwelveData (e.g. obscure OTC stocks) returns empty or error data

## How this service works

Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.

## Output

Returns a JSON object with a `data` field containing the TwelveData API response (e.g. quote, OHLCV, indicator values), a `provider` field confirming 'twelvedata', and an `operation` field echoing the requested operation (e.g. 'quote').
