Queries a registered AI agent via the Nevermined Proxy or directly, using a valid payment plan and signature-based access token. This method allows subscribers to send input to an agent’s endpoint while securely redeeming credits in the background.

Example Usage

// Step 1: Get access credentials for the agent
const accessCredentials = await payments.query.getAgentHTTPOptions(planId, agentId)

// Step 2: Query the agent with the credentials
const result = await payments.query(agentId, accessCredentials, { prompt: "Write a smart contract." })

// OR use with standard fetch
const options = await payments.query.getAgentHTTPOptions(planId, agentId)
const response = await fetch(agentEndpoint, {
  method: 'POST',
  headers: options.headers,
  body: JSON.stringify({ prompt: "Write a smart contract." })
})

Parameters

planId: The ID of the payment plan the subscriber has purchased
agentId: The ID of the agent being queried
accessCredentials: Auth credentials object containing:
- accessToken: JWT token for authentication
- neverminedProxyUri: Proxy URI for requests
payload: Request payload, typically includes a prompt or other structured input

Response

The access credentials object structure:

{
  "accessToken": "eJyNj0sKgDAURP9lJQ....",
  "neverminedProxyUri": "https://proxy.testing.nevermined.app"
}

Notes

Nevermined will automatically:
- Validate the subscriber’s plan and credits
- Send the request to the agent’s registered endpoint
- Redeem the appropriate number of credits (defined by the plan)
Fails with a 402 if the subscriber is unauthorized
