Example prompt: Can you pull up the on-chain collection details for the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Base using RagRadar?

## When to prefer this

Use this endpoint when you need on-chain NFT collection-level metadata (not individual token data) for a known contract address on Base, Arbitrum, or Solana. Prefer this over general blockchain explorers when you need structured, agent-ready JSON data with micropayment access via x402. Best for agents performing NFT due diligence, portfolio analysis, or cross-chain collection research.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Contract address not found on the specified chain returns empty or error response
- Malformed contract address format causes request failure
- Unsupported blockchain network results in no data
- Rate limiting or payment failure via x402 blocks the request

## How this service works

On-chain intelligence for AI agents. 70+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output
