Method
- One search per task and index, same phrase everywhere. Tanod’s index uses the task’s keyword (in the data), because it matches name or URL substrings.
- Each top-3 result got one unpaid request. Payable: an x402 or MPP 402 challenge, a USDC price at most USD 1, and an input schema. Verified: also a successful seller-offered free or test call.
- On-task: name, description or URL matches task keywords. This is a coarse test, not a service-quality guarantee. Result order is the index’s own.
- Nothing was paid. Requests were at most one a second, on 2026-11-02. Indexes and sellers change.
- Tanod sells tools and runs one index. Seller identities and individual listings are omitted.
