• GET/api/weather-current—No price listedCurrent weather conditions for any location on Earth: temperature, feels-like, humidity, wind speed/direction/gusts, precipitation, cloud cover, pressure, and human-readable condition. No key, global. Also on x402 Bazaar
• POST/api/scrypt-derive—No price listed
• POST/v1/auto/chat/completions—No price listedOpenAI-compatible chat completions with the model chosen server-side: omit model and the gateway routes the prompt to the top-ranked model for its task (code, reasoning, long-context, general) from a fixed eval-derived ranking, failing over automatically on provider errors. Flat price per call, 16k chars in, 1024 tokens out, streaming supported. Use it as a drop-in OpenAI base_url when you want good answers without picking a model. Also on x402 Bazaar
• POST/api/evm-rpc—No price listedRead-only JSON-RPC against Ethereum, Base, Polygon, Arbitrum, or Optimism with built-in multi-endpoint failover - one paid call, no node or API key of your own. Prefer the named reads (block-number, chain-info, block-info, event-logs, erc721-owner, contract-code) for common tasks - they validate inputs and cost less; use this when you need a whitelisted method they do not wrap. Also on x402 Bazaar
• POST/api/email-validate—No price listedValidate an email address: syntax check plus live MX record lookup on the domain (deliverability signal, not a guarantee). Also on x402 Bazaar

• GET/api/chain/nonce—No price listedThe transaction count of an account, which is the nonce its next transaction must carry. Ask for block "pending" to include transactions already in the mempool, which is what you want before signing; the default "latest" counts only mined transactions. Returns the count as a decimal string and as hex. EVM chains: ethereum, base, polygon, arbitrum, optimism. Also on x402 Bazaar

• POST/api/matrix-multiply—No price listed
• POST/api/iso-week—No price listedGet the ISO 8601 week number, ISO day-of-week, quarter, and day-of-year for any date. Useful for fiscal/reporting calendars, weekly aggregations, and sprint planning. Also on x402 Bazaar

• POST/api/perp-dexs—No price listedEvery builder-deployed perpetuals dex on Hyperliquid (HIP-3): dex name, full name, deployer, oracle updater and fee recipient, how many markets it lists (active vs delisted, so a wound-down dex reads as one), how many assets carry a streaming open-interest cap and the cap total, plus the current perp-deploy auction (start, end, start/current/end gas). The native dex is not a row; use perp-markets for it. Keyless public data. Also on x402 Bazaar
• POST/api/dex-pool—No price listedRead on-chain state of a Uniswap V3 pool: token0/token1 addresses + decimals, fee tier, current sqrtPriceX96, tick, in-range liquidity, and the decoded human-readable spot price (token1 per token0).
