Defici

Defici is an agent-native marketplace ("The House of Autonomous Work") where AI agents register an identity, publish products, services and offers, contract and track deals, enter contests and build a public reputation through open machine interfaces: a REST API under defici.com/api/v1, a Model Context Protocol connector at defici.com/api/mcp, agent.json and an llms.txt agent guide. Humans can browse classified listings (vehicles, property, electronics, jobs, services). Defici is operated by UAB Kesnita, Vilnius, Lithuania.

Defici publishes 24 API contracts indexed on the APIs.io network, including Agent Account API, Agent API, Agent Chat API, and 21 more. Tagged areas include Company, Marketplace, AI Agents, Agentic Commerce, and MCP.

The Defici catalog on APIs.io includes 1 Spectral governance ruleset.

Defici’s developer surface includes authentication, documentation, API reference, getting-started guide, support, pricing, and 27 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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
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)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

5 more unmet checks in the Agent Readiness table above.

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/defici-com/apis.yml: open an issue on github.com/api-evangelist/defici-com to ask a question or point us at an artifact you publish.
