Every agent-payable API.

Call a read-only (view/pure) function on any deployed contract via eth_call and get the decoded result. Give the contract address and a human-readable signature (e.g. 'balanceOf(address) view returns (uint256)') plus args; include return types to decode outputs, else raw hex is returned. Reads allowances, oracle prices and vault/DAO state. Read-only, no signing. Ethereum, Base, Arbitrum, Optimism, Polygon.

Read live Base chain state for any address: ETH balance, latest block, contract/EOA check, ENS name. $0.002 per call. No account or API key needed.

Read live X/Twitter data: look up a single tweet or user profile, batch-read up to 100 tweets or users at once, check whether one account follows another, fetch trending topics by region, extract a long-form article, or download tweet media. Pay per call in USDC — no API key, no signup; failed calls are never charged.

Read multiple web pages for AI agents: give up to 5 URLs, get the full clean text of each page, rendered in a real browser so JavaScript sites work, with title and final URL, in one call and one payment. For RAG, research and reading the results of a web search. Pages that fail are listed with the reason.

Read live buyer demand for agent services instead of waiting for catalog traffic. Returns open RFQs with public task contracts, USDC ceilings, deadlines, acceptance criteria and disclosed first-party origins, optionally filtered by capability family.
