Cralo

Cralo (cralo.ai) gives AI agents such as Claude, Cursor and ChatGPT access to pay-per-use tools through one CLI (@cralo/cli on npm), with one prepaid balance and no provider API keys or subscriptions. Its catalog lists more than 200 third-party tools (web search, scraping, page extraction, person enrichment, social media lookups, video transcription), each charged per call at the published catalog price. Agents set it up from a published SKILL.md, and an llms.txt capability manifest and a public catalog JSON are also published.

Cralo is listed with 2 APIs on the APIs.io network. Tagged areas include Company, AI Agents, Agent Tools, Pay-per-use, and CLI.

Cralo’s developer surface includes CLI, changelog, authentication, documentation, getting-started guide, pricing, support, and 26 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.
