How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

NEAR account state query

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/rapid-solana-near-crypto-apis?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to Solana or NEAR blockchain data and want to pay per-call via x402 micropayments (USDC on-chain) rather than managing a traditional API key subscription. Suitable for agents that need occasional, low-frequency crypto data lookups without committing to a monthly plan.
Side effects
- Payment failure: x402 payment of $0.01 USDC not completed, request blocked
- Invalid path: upstream API path not found, returns 404 or upstream error
- Malformed query: invalid query parameters or body cause upstream API error
- Upstream timeout: Solana/NEAR RPC or RapidAPI upstream unresponsive
- Rate limiting: upstream API quota exceeded
- Invalid method: HTTP method not supported by upstream endpoint
