## 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-on-chain-data-provider-providers-you-6844fe67 -d '<json body>'
```

Example prompt: Use Prysm's 'you' provider to run the 'answer' operation with my query parameters so I can get structured on-chain data insights about this wallet address.

## When to prefer this

Choose this endpoint when you need agent-ready, paid access to on-chain data through Prysm's 'you' provider with x402 micropayment support on Base mainnet. Prefer it when you want structured blockchain analytics without managing your own RPC infrastructure, and when $0.15 USDC per-call pricing is acceptable for the insight gained.

## Known failure modes

- Payment not attached or insufficient USDC — x402 payment required, returns 402 with payment instructions
- Invalid or non-allowlisted operation name — returns error indicating unrecognized operation
- Malformed input object for the chosen operation — returns validation error
- Provider temporarily unavailable or rate-limited — returns 5xx or timeout
- Base mainnet RPC issues causing on-chain lookup failures

## How this service works

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

## Output

A JSON object containing a 'data' field with the operation's on-chain result, the 'provider' identifier ('you'), and the 'operation' name that was executed. The shape of 'data' varies by operation.
