How this service works
66 pay-per-call APIs: AI text/image generation ($0.01), Polymarket odds, crypto prices, DeFi yields, FX rates, weather, IP/geo, FBI wanted, SEC tickers, clinical trials, 250M academic papers, Stack Overflow, meme-coin launchpads (pump.fun, Clanker, Four.meme, SunPump), tokenized stocks, Solana top 100, and 40+ more. $0.005/call standard. USDC on Base and Solana via x402.
Output
A JSON object containing the answer to the prompt, shaped by the requested fields if specified — could be utility output (encoded string, hash, UUID, timestamp, IP), search results (list of matching records with relevant metadata), price data (venue-level SOL spread), or verification status (NPI/DEA record fields).
Example use cases
Healthcare provider NPI verification
“Can you verify this NPI number 1234567890 for me and confirm the provider's name, specialty, and DEA registration status?”
Live SOL multi-venue price spread
“What's the current SOL price spread across all trading venues right now — show me bid, ask, and which exchange has the best spread?”
Quick base64 encode and UUID generation
“Encode the string 'hello world' in base64 and also generate a fresh UUID for me — I need both for a quick test.”
Technical details
Endpoint
GEThttps://workspace-x402-paywall.onrender.com/ai/ask?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single pay-per-call gateway covering a wide range of micro-utilities and live data lookups without managing separate API keys for each provider — especially useful for agents that need occasional, ad-hoc access to utilities, healthcare provider verification, academic search, or crypto pricing without subscription overhead. Ideal when you want micropayment billing via USDC on Base or Solana rather than traditional API key billing.
Side effects
- Payment not provided or insufficient USDC — returns HTTP 402 requiring x402 payment header
- Prompt too vague or ambiguous — returns generic or empty response
- Requested data source unavailable or rate-limited — partial or error response
- NPI/DEA number not found in registry — returns not-found indicator
- Invalid base64 or hash input — returns error message
- Network timeout on external data source — delayed or failed response
