How to use this page & what the results mean
How to use this page
- Browse the neutral directory of agent-payable endpoints across x402 / MPP / AP2.
- Search, filter by category / protocol, and sort by relevance, calls, spend, availability, latency, rating or price.
- Click Register endpoint to list or claim your own endpoint (requires an API key). Enter the exact URL agents call, a recognizable display name, protocol, price and chain.
- For Price, enter the smallest token unit (for example
1000000 = 1 USDC). For Chain, use CAIP-2 format such aseip155:8453. Add a short description so buyers know what the endpoint does. - Click Set up payouts only if you are a seller and want to connect Stripe for marketplace earnings.
What the results mean
- Endpoints — total listed endpoints (with a category breakdown). Featured — paid slots; Verified — KYA-badged count.
- Total calls — aggregate calls across all Harpd tenants, not just yours.
- Each card shows protocol, category, price, rating, availability %, calls, spend, reliability % and latency.
- Quality scores are aggregated globally from every tenant’s real payment events.
- Register publishes a directory listing; it does not deploy or change your API. Test the endpoint and selected protocol before submitting.
Buyer: use Search and filters to compare endpoints. Seller: register only an endpoint you control, then connect payouts separately if you want to receive earnings.
