ChimpanSEO

ChimpanSEO is a GEO (generative engine optimization) and AI SEO software service, built and operated independently in Italy, that writes articles structured for extraction and citation by AI answer engines such as ChatGPT, Perplexity and Google AI Overviews, based on 9 optimization methods from academic GEO research (KDD 2024). It connects to WordPress sites to publish drafts or live posts, schedules them on an editorial calendar, scores each article for AEO quality, offers a free SEO audit, and exposes a remote MCP server (Streamable HTTP, Bearer API key) so AI agents like Claude Code and Cursor can run the same workflow. Plans start from EUR 19/month with a 15-day free trial.

ChimpanSEO publishes 2 API contracts indexed on the APIs.io network: Audit API and MCP API. Tagged areas include Company, SEO, Generative Engine Optimization, AI Content, and Content Marketing.

The ChimpanSEO catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

ChimpanSEO’s developer surface includes getting-started guide, API reference, authentication, documentation, engineering blog, support, signup flow, and 32 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 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0 Ask about this →
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document Ask about this →
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented) Ask about this →

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 the provider profile at artifacts.apis.io/chimpanseo-app/apis.yml: open an issue on github.com/api-evangelist/chimpanseo-app to ask a question or point us at an artifact you publish. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
