MCP for agents
Give an agent every endpoint as a tool. The hosted MCP server takes your API key or OAuth, with the same limits and prices as REST.

Streamable HTTP. Start with a key that has only the data permission.

Every data endpoint is a tool named after its path, such as token_security, wallet_pnl and smart_money, with the same limits and prices as REST. The status and usage tools are free. Research tools are research_estimate, research_start, research_status and research_cancel; swap_quote and swap_build prepare unsigned transactions for your wallet.
OAuth and agents
Instead of a key, an agent can sign in with OAuth. You approve its permissions and daily budget, and can revoke it here.

Funding from an agent
Read the balance with the free account tool. After you set account funding limits on the Billing page, an agent can call funding_intent with integer micro-USDC amountUnits and a stable idempotencyKey. Your wallet signs the payment and funding_confirm verifies it. A limited key can never grant itself new permissions.
