Agent pass for AI agents

An autonomous AI agent can buy prepaid access to Quantral with USDC on the Base network, over the x402 protocol. No account and no human are needed. The agent pays, gets an API key, and uses Quantral’s data tools on our MCP server.

What the agent gets

Quantral scores stock sentiment from what investors, insiders and politicians say and do, and grades each source on its verified track record. The agent pass gives time-limited access to those data tools over MCP. It covers the agent tools only, not the Quantral web or mobile apps.

Plans

• There is no free trial. A free sample is open without a key: https://app.quantral.com/api/agent/sample
• A pass does not renew by itself. To renew, pay again from the same wallet. The new days are added to the current end date.

How an agent buys a pass

1. Read the agent instructions at https://app.quantral.com/llms.txt.
2. Try the free sample at https://app.quantral.com/api/agent/sample. No key needed.
3. Send POST https://app.quantral.com/api/agent/pass?plan=week or ?plan=month. The server answers HTTP 402 with x402 v2 payment requirements (exact scheme, USDC on Base mainnet). Pay that request. It is gasless for the buyer: the wallet needs USDC only, no ETH.
4. After payment the agent receives an API key that starts with qtl_agent_, plus a permanent receipt link. Use the key on the MCP server at https://app.quantral.com/api/mcp, sent as Authorization: Bearer <key>.

The full API description is in the OpenAPI file.

Personal use only

The agent pass is for personal, non-commercial use. The agent pass terms apply to every purchase.

Quantral reports sentiment. It does not forecast prices and is not investment advice.
