A4.2/5.0
Scored across 1 tool
Disambiguation5/5
There is only one tool, so there is no possibility of misselection between tools. The tool's purpose (find paid x402 APIs matching an agent's need) is stated explicitly and unambiguously.
Naming Consistency4/5
The single name find_paid_api follows a clear, readable verb_noun snake_case convention. With only one tool there is no pattern to compare against, which caps the confidence slightly, but nothing is inconsistent.
Tool Count3/5
A single tool is thin for a discovery-and-verification service; the description crams four distinct capabilities (search, lite detail, live 402 pick, market report) into one entry. It works as a focused entry point but leaves the surface feeling under-decomposed.
Completeness3/5
Search is covered with filters and ranking, but the deeper operations (/v1/lite, /v1/pick, /v1/market) exist only as prose in the description rather than as distinct callable tools. An agent cannot reliably discover or invoke those capabilities as tools, leaving notable gaps in the lifecycle from discovery to verification.

Which paid API should my agent call? Searches the 36,000+ paid x402 resources on the public x402 discovery indexes and returns how many match your need, how many seller hosts there are, and the top 3 services ranked by relevance, 30-day unique payers and calls, recency and price (service name, USD price, networks, payers). Optional max_price and network filters. Free preview tier. The paid x402 routes add resource URLs and usage detail for the top 5 (/v1/lite), live 402 checks of the top candidates with a best verified pick (/v1/pick) and a market report with price quartiles and top sellers (/v1/market).
Inputs: need (required), network, max_price.
