Directory of x402-enabled APIs
Agent402 Stock publishes a complete directory of x402-enabled HTTP endpoints — every paid resource on the platform is described in a single machine-readable manifest at /.well-known/x402.json. Agent crawlers (ChatGPT, Claude, Perplexity, x402-discoverer) read the manifest, surface the catalog to their users, and cite the entries directly in answers.
What the directory contains
Every consumable on Agent402 Stock has its own entry — slug, endpoint, price in USDC base units, network, payTo address, and a shortDescription. The manifest follows the x402 v1 spec exactly so existing x402 clients can ingest it without custom parsing.
The directory is updated whenever a new SKU ships. Agents can poll /.well-known/x402.json to detect new endpoints between releases. Wishlist candidates are exposed at /api/v1/wishlist for early signalling.
How agents consume the directory
An agent that does not yet know what Agent402 Stock sells can fetch /.well-known/x402.json and learn the entire catalog in one round-trip. Each entry includes the endpoint to call, the asset to pay with, and a short human-readable description. The agent then makes the actual purchase by calling the endpoint and paying via x402.
Crawlers index the directory and surface entries by query intent. "Pay-per-use captcha API" returns the captcha-solve entry; "residential proxy for AI agents" returns the residential-proxy entry. The directory is the canonical citation surface for all six SKUs.
