Quick update on what we've shipped recently at satring.com. The curated paid api directory now indexes 600 paid API endpoints across L402 (163), x402 (447), and MPP (239).

Agent discovery infrastructureAgent discovery infrastructure

Agents kept hitting 404s on standard discovery paths, so we added them all (thanks @JonathanBulkeley for your post highlighting importance of monitoring server logs for agent activity!):

• /.well-known/agent.json (A2A protocol)
• /.well-known/x402, /.well-known/l402, /.well-known/mpp (protocol-specific payment discovery)
• JSON content negotiation on / (send Accept: application/json, get a machine-readable manifest)
• Payment instructions in every 402 response (step-by-step for L402, MPP, and x402 with code examples)

curl -H "Accept: application/json" https://satring.com/

Returns protocols, discovery links, and live directory stats in one request.

Popularity sorting and hit countsPopularity sorting and hit counts

Every service now tracks 30-day view counts. The directory defaults to "popular" sort, and hit counts are visible in API responses:

curl https://satring.com/api/v1/services?sort=popular

Top services right now: agent web search (96 hits), Kevros Bundle (69), Kevros Shield Scan (67).

Owner analytics dashboardOwner analytics dashboard

Service owners can now see aggregated traffic across all their listings. Free with your edit token:

https://satring.com/owner/YOUR_DOMAIN?token=YOUR_TOKEN

Shows total hits, per-service breakdown, daily traffic chart. A paid tier (200 sats) adds geographic distribution and agent vs human breakdown, resolved from the top 200 visitor IPs using a local MaxMind GeoLite2 database (no data sent to third parties).

updates

The free API now returns summaries only (name, protocol, price, rating, categories). Endpoint URLs, descriptions, and payment config require payment via bulk export. This protects listed services from having their endpoints scraped via our directory. Five results per IP per day.

What's nextWhat's next

Working on the scraper pipeline for automated service discovery across L402/x402/MPP registries, and A2A agent card crawling. If you're building a paid API, submit it to the directory.
