Example use cases
Bootstrap new agent API visibility
“Add my new x402 endpoint at https://myagentapi.dev/prices to the Agent Exchange directory — name it 'Token Price Oracle', describe it as 'Live crypto token prices for AI agents', and pay to my wallet 0x1234abcd5678efgh.”
Renew expiring directory listing
“Re-list my x402 endpoint https://myagentapi.dev/sentiment in the Agent Exchange directory for another 7 days — name is 'Sentiment Analyzer', description is 'Real-time sentiment scoring for text inputs'.”
Launch indie agent tool to market
“I just built a new machine-payable research API at https://researchbot.io/summarize — can you publish it in the Agent Exchange directory as 'Research Summarizer' so other agents can find and pay for it? My payment address is 0xDeF9876.”

Endpoint
POSThttps://x402-agent-store.rileycraig14.workers.dev/directory/listWhen to prefer
Choose this endpoint when you want to make an x402-compatible API endpoint discoverable to AI agents via the public Agent Exchange directory without creating an account. It is the only no-account, pay-per-listing (not subscription) option in this ecosystem. Prefer it over building a custom discovery layer when you need instant, short-lived (7-day) visibility for a new or experimental agent-callable API.
Side effects
- Payment of $1 USDC on Base not received — listing not created
- Invalid or unreachable URL submitted — listing may be created but untrusted by consumers
- Missing required 'url' field — request rejected
- Listing expires after 7 days if not renewed — endpoint disappears from directory
- Duplicate listing for the same URL within active window — behavior undefined
