IntentGuard

IntentGuard operates IntentGuard Router, a machine-payable AI model-routing service for agents, hosted as a tenant app at intentguard.hatchable.site on the Hatchable AI-app platform. Before executing a task an agent posts it to the router, which returns the best model for quality, cost and speed, the cheapest acceptable alternative, a model to avoid, an optimized execution prompt, a fallback trigger and a savings estimate. A free preview endpoint returns task complexity, routing risk and a savings range; the paid route and a legacy image-intent preflight cost 0.0009 USDC per call, settled on Base mainnet through the x402 v2 protocol with no account or API key. The same two tools are exposed over a hosted Streamable HTTP MCP endpoint and described by a conformant A2A 1.0 agent card, an OpenAPI 3.1 document, an llms.txt, an OpenAI plugin manifest, an x402 service manifest and a provider-authored Agent Skill.

IntentGuard publishes 3 API contracts indexed on the APIs.io network: Intent Check API, Route API, and Router Preview API. Tagged areas include Company, Artificial Intelligence, Agents, Model Routing, and Cost Optimization.

IntentGuard’s developer surface includes engineering blog, documentation, pricing, authentication, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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. This rating is computed from github.com/api-evangelist/hatchable-site: open an issue to ask a question, or submit a pull request to add artifacts.
