Send this

Prompt for your agent

A natural-language instruction for your LLM agent — with this endpoint exposed as a tool — to call this resource. Not sent to the endpoint; the endpoint consumes the JSON body below.

Pasting this prompt into a raw ChatGPT or unconfigured agent will notexecute the paid endpoint flow. Run it through an agent with the AXON runtime / MCP tools exposed (see “Use with AXON” above) so the 402 challenge, quote, and governed fetch are handled for you.

“Check if the wallet holds the required NFT and has sufficient USDT balance for premium access”

Endpoint request body

The JSON payload your agent sends to the endpoint.

{
  "nftContract": "0x...",
  "walletAddress": "0x...",
  "minUsdtBalance": "1000000"
