Scored across 2 tools
The two tools have clearly distinct roles: list_apis provides the API index and counts, while search_plans retrieves plan-level results. The descriptions explicitly guide the agent to use list_apis first when API names are unknown, then search_plans, leaving little room for misselection.
Both names follow a consistent snake_case verb_noun pattern: list_apis and search_plans. The naming is predictable and directly reflects each tool's action and resource.
Two tools is minimal but well matched to a focused read-only API-plan directory: one to list APIs and one to search plans. It is slightly below the typical 3-15 tool range, but the small surface is reasonable for the scope.
For a read-only directory, the surface covers both browsing the API index and searching plan details with filtering, sorting, and pagination. No create/update/delete operations are expected, and the available tools provide a complete discovery workflow.

2 toolslist_apisList the APIsARead-onlyIdempotentInspect
Lists the APIs on Datacircle's sheet and the number of plans and providers for each. Pass an API's name to search_plans. It takes no arguments and gives the whole sheet in one answer, every API in the sheet's order, with no paging: each API's name (api), how many plans (plans) and providers (providers) it has, its sheet (sheetPage) and, where it has one, its best page (bestPage), which ranks its providers on our benchmark. Call it first when you don't know an API's name; when you do, call search_plans with it straight away. Free, no key, read-only.
Inputs: no named parameters. Returns: apis
search_plansSearch the API plansARead-onlyIdempotentInspect
Searches Datacircle's sheet of API plans and gives the ones that match, best first unless you sort them. Call list_apis first for the APIs' names, then pass one as api for that API's plans; leave api out to search every API at once. Add query to find a provider or a plan by name, and sort by price for the cheapest first. Each plan holds every key of the sheet's JSON download: its provider, plan, billing, $ per 1,000 (perThousand), score out of 100 (score), rate limits, speed, the fields it returns and its page on datacircle.dev (page). What each key means: https://datacircle.dev/fields. With api, the answer links the API's sheet (sheetPage) and its best page (bestPage), which ranks its providers on our benchmark. total counts every plan found, and plans holds up to limit of them (10 unless you say, at most 50) from offset: page through the rest with offset. When no plan matches, you get total 0 and an empty plans list, not an error; an argument its schema doesn't allow, like an api list_apis doesn't give, is an error that says what it takes. Free, no key, read-only.
Inputs: api, sort, limit, query, +1 more. Returns: plans, total, offset, bestPage, +1 more
