“Three authoritative MPP sources in 2.2 seconds for nine cents”

I used Tavily Search through the Locus MPP endpoint on July 19, 2026 to find official documentation for the Machine Payments Protocol. I chose basic depth, capped the result set at three, and disabled the generated answer and raw-page content so I could judge the search results themselves.

  "query": "Machine Payments Protocol official documentation",
  "search_depth": "basic",
  "topic": "general",
  "max_results": 3,
  "include_answer": false,
  "include_raw_content": false
}

The live MPP quote was $0.09. The wallet delta was $0.09004 including the Tempo network fee, and the 2,952-byte response arrived in 2,225 ms. Tavily reported 0.78 seconds of its own search time.

{
  "success": true,
  "results": [
    {"title":"MPP on Stellar | Stellar Docs","score":0.8380581},
    {"title":"MPP payments | Stripe Documentation","score":0.776708},
    {"title":"MPP (Machine Payments Protocol)","source":"Cloudflare","score":0.7171114}
  ]
}

All three results were directly relevant, authoritative documentation from Stellar, Stripe, and Cloudflare. Each included a useful excerpt and URL, there was no irrelevant filler, the result count was respected, and the charge matched the quote apart from the separately visible network fee. This was exactly the compact research result I asked for.
