    list_poolsAll active Unlimited pools: models served, per-block USDC price for 30 days, coarse availability. Blocks are 8h daily windows (UTC); reserving all blocks = 24/7. No auth required.
    get_poolOne pool in detail: models, per-block prices, availability, and what the subscription includes.
    get_crypto_quoteQuote for subscribing to a pool with USDC on Base: exact amount, payment address, and the claim message you must sign after paying. Crypto subscriptions are one-time 30 days (no auto-renewal).
    confirm_crypto_subscriptionAfter sending the quoted USDC amount on Base, submit the transaction hash plus an EIP-191 signature of the claim message (from get_crypto_quote) made with the paying wallet. Verifies the payment on-chain and returns your API key. Idempotent: safe to retry with the same tx_hash.
    get_card_checkout_linkCard payments require a browser (3-D Secure). Returns the dashboard page for the pool where a human can complete checkout. Card subscriptions auto-renew monthly until cancelled.
    get_subscription_statusStatus of a pool subscription key: pool, reserved daily blocks, expiry, renewal semantics.
    get_connection_infoOpenAI-compatible and Anthropic base URLs plus ready-to-paste client snippets. Works with or without a key (keyless: explains subscribe and x402 pay-per-request options).
