How this service works
Pay $1 USDC on Base to list your x402 endpoint in the public Agent Exchange directory. GET /directory is free. Body: { url, name?, description?, payTo? }. No account. Listing is live immediately and expires in 7 days unless renewed.
Output
A confirmation that the listing is live in the Agent Exchange public directory, along with the listing ID and expiry timestamp (7 days from submission). The endpoint is immediately discoverable via GET /directory.
Example use cases
Bootstrap a new x402 API's discoverability
“I just launched my x402 endpoint at https://api.weatherbot.xyz/forecast — can you list it in the Agent Exchange directory as 'WeatherBot Forecast' with description 'Hourly weather forecasts for any city, machine-payable via x402'? Pay the $1 USDC fee to get it live.”
Promote an on-chain data feed to agent builders
“Add my on-chain NFT floor price endpoint at https://data.nftprice.io/floor to the Agent Exchange directory — name it 'NFT Floor Oracle', describe it as 'Live NFT collection floor prices via x402', and use 0xABC123... as the payTo address.”
Renew an expiring directory listing
“My listing for https://api.tradesignal.io/signals is about to expire — please re-submit it to the Agent Exchange directory with the same name 'TradeSignal Feed' and description 'Crypto trade signals, $0.05 per call' to get another 7 days of visibility.”
Technical details
Endpoint
POSThttps://store.agentexchange.work/directory/listWhen to prefer
Use this endpoint when you want to make an x402-protocol API discoverable to AI agents and developers browsing the Agent Exchange public directory. It is the canonical submission endpoint for the Agent Exchange marketplace and requires no account — just a $1 USDC payment on Base. Prefer this over manual outreach or other directories when your target audience is AI agents or agent builders looking for machine-payable APIs.
