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.
Example use cases
Wallet on-chain activity lookup
“Pull on-chain activity data for wallet address 0xAbC123... using Prysm — I want to see what the 'answer' operation returns for this address.”
DeFi protocol data query
“Query Prysm's you-provider with the 'answer' operation to get on-chain metrics for the Uniswap contract at 0xDEF456 on Base mainnet.”
Agent-driven blockchain analytics
“I need Prysm to analyze on-chain data for token 0x789GHI — run the allowlisted operation and give me the structured result so I can include it in my report.”
Technical details
Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/you?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
