Arphie is an AI-powered knowledge activation platform that helps go-to-market teams automate RFP (Request for Proposal) responses, security questionnaires, and due-diligence questionnaires. Its AI agents draft answers from a company's knowledge base, cite sources with confidence scores, and integrate with knowledge sources such as Google Drive, SharePoint, Confluence, Notion, Seismic, and Highspot. Arphie is used by high-growth and publicly traded companies to win more deals faster while keeping proposal content accurate, current, and auditable. The company is SOC 2 Type 2 compliant, operates zero data retention with model providers, supports SAML 2.0 SSO and role-based access controls, and is backed by General Catalyst. Arphie publishes no REST API and no OpenAPI, but it does operate a live, remote Model Context Protocol server at https://app.arphie.ai/api/mcp — OAuth-protected, with RFC 9728 protected-resource discovery — that brings Arphie projects, workload metrics, and agentic chat into Claude, ChatGPT, Cursor, an IDE, or the terminal. Arphie also serves an llms.txt for AI agents. This profile was surfaced as a portfolio lead and enriched by the API Evangelist pipeline.
Arphie is listed with 1 API on the APIs.io network. Tagged areas include Company, Enterprise, Artificial Intelligence, Sales Enablement, and RFP Automation.
Arphie’s developer surface includes signup flow, engineering blog, support, documentation, getting-started guide, authentication, and 18 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/.

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)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
7 more unmet checks in the Agent Readiness table above.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

note: No REST API and no OpenAPI (probed /openapi.json, /openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs, /docs,
/redoc on www., api., app. and docs.arphie.ai — all 404). STEP 0b contract discovery instead found a live, OAuth-protected
remote MCP server at https://app.arphie.ai/api/mcp (401 with RFC 9728 resource_metadata; control paths 404), which is
Arphie's real machine-readable surface. tools/list is auth-gated, so tool names and inputSchemas are not recorded. No
A2A agent card (every /.well-known/* on app.arphie.ai is an SPA shell). Pricing is a password-protected 401.
