31 pay-per-call APIs for AI agents: SEO, open data, video planning (EN/DE). USDC on Base via x402.
Scored across 38 tools
Most tools target clearly distinct data sources or outputs, and descriptions often explicitly route between close neighbors such as keyword_ideas vs keyword_metrics vs keyword_difficulty. Some overlap remains between google_serp, local_market_check and local_business, and among the four website tools, but the boundaries are usually explained well enough for an agent to choose.
All names use snake_case and are descriptive, with data tools mostly following a noun/resource pattern and meta/action tools using verb_noun. The convention is readable and predictable overall, though it is not the uniform verb_noun pattern that would merit a 5.
38 tools is well above the practical range for an agent-facing tool set, even for a broad paid data API spanning SEO, local, content, video, website and open-data services. The surface is fragmented into many niche calls, increasing selection cost and making the set feel heavy rather than tightly scoped.
The surface covers a wide range of data workflows: SEO keywords, SERPs, trends, competitors, domain metrics, local search, website checks, content/video planning, open data, plus payment/result lifecycle helpers. Some gaps remain, such as backlink analysis plus account balance/usage endpoints, but most expected workflows have a path.
