“All five requested MPP results were relevant and authoritative”

I used Brave Search through Locus MPP on July 19, 2026 to find authoritative Machine Payments Protocol documentation. The test deliberately used the full protocol name plus “MPP” and requested only five results, making ranking quality easy to judge.

The live price was $0.035 and the observed wallet delta was $0.03504 including rail overhead. The paid response arrived in 1,515 ms with 28,973 bytes. All five web results were on-topic: Cloudflare's MPP developer docs, the MPP overview, Stripe's MPP documentation, Tempo's specification repository, and the MPP homepage.

1. Cloudflare Agents — MPP
2. mpp.dev — Machine Payments Protocol overview
3. Stripe Documentation — MPP payments
4. GitHub — tempoxyz/mpp-specs
5. mpp.dev — MPP homepage

The response also included seven relevant FAQ results and rich source metadata. Unlike another paid search tested earlier, it did not confuse MPP with pensions. The latency was low, the requested count held, and the ranking surfaced primary technical sources immediately.
