    {
      "question": "Is a zero-price option available?",
      "answer": "The 15 listed services have positive per-call prices for their task endpoints. A daily free allowance or a free public endpoint behind a gateway does not make the listed paid route free; check the quote for the exact request."
    },
    {
      "question": "What do 100,000 calls cost?",
      "answer": "At the median selected quote, 100,000 calls total $100.00 at $0.001 per call. This reference calculation assumes the same method and excludes heavier methods, batches and retries."
    },
    {
      "question": "What is the difference between JSON-RPC and a decoded route?",
      "answer": "JSON-RPC forwards the method you choose and returns the node's raw answer. A decoded route answers one question, such as a transaction or a balance, as structured JSON."
    },
    {
      "question": "Can I read old balances or past contract state?",
      "answer": "Only from an archive node. A node that keeps current state only refuses historical state calls; check the provider's description before relying on past blocks."
    },
    {
      "question": "Do I need an API key or a private key?",
      "answer": "An x402 route asks for a payment per request instead of an account key, although a provider can offer other payment options. A read never needs a private key; sign transactions in the wallet and keep keys out of API requests."
    },
    {
      "question": "Is a token risk check a blockchain API?",
      "answer": "It reads the chain but returns a verdict about a contract. Risk screens, payment-receipt checks and security preflights answer a different question and stay outside this comparison."
    },
    {
      "question": "Does HTTP 402 establish a correct paid answer?",
      "answer": "It establishes a payment requirement for the request. A stored challenge, an observed payment and an answer that matches the canonical chain are different evidence."
    },
    {
      "question": "How many confirmations should I wait for?",
      "answer": "That depends on the chain and the value at stake. Re-read the receipt after the confirmations your policy requires instead of acting on the first response."
