How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns structured Solana/DeFi blockchain data sourced from Helius infrastructure, such as parsed transaction histories, token balances, account details, or NFT metadata, depending on query parameters passed. Response is JSON containing on-chain data fields relevant to the queried entity.
Example use cases
Solana wallet activity audit
“Show me the recent on-chain transaction history for Solana address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM — I want to see what DeFi activity has happened there.”
Token transfer tracking for DeFi
“Fetch all token transfers involving mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v from the SperaxOS Helius data API so I can track USDC movements on Solana.”
No-API-key Solana data lookup
“I need Helius Solana blockchain data for account Fg6PaFpoGXkYsidMpWTK6W2BeZ7FEfcYkg476zPFsLnS without signing up for a Helius API key — just pay per request with USDC.”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/v1/data/helius?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Solana/Helius blockchain data without committing to a Helius API key subscription, prefer pay-per-request micropayment billing via x402 USDC on Base, or are building an AI agent that dynamically queries on-chain DeFi data only when needed. It is best suited for low-frequency, on-demand Solana data lookups where per-call cost ($0.001 USDC) is acceptable over a monthly subscription.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or malformed Solana address/signature — returns 400 Bad Request
- Helius upstream outage — returns 503 or timeout
- Rate limit exceeded even with payment — returns 429
- Missing required query parameters — returns 400 with parameter error
