the402.ai serves agents that need to pay micropayments (USDC on Base) for individual utility operations without managing subscriptions or API keys in the traditional sense. It covers a narrow but practical set of tasks — visual capture, transactional email, domain intelligence, and text sentiment — unified by a common job-tracking layer. It is distinct from general-purpose LLM APIs or data marketplaces; its value is the x402 payment-gated, job-ID-based execution model for these specific utility services.

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
Make my x402 API at https://api.the402.ai discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://api.the402.ai --json`. Heads up: 5 routes have never been scored and 47 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
