Breef
Breef is an online agency marketplace and payments platform that connects brands with vetted marketing, creative, digital and web agencies. Founded in New York in 2019 as Curated and rebranded to Breef in 2021, the company is now headquartered in Denver. Brands scope a project on the platform, receive curated pitches from hand-picked agencies across 50+ project types in days rather than months, and then run contracts, milestones and payments through Breef — including Breef(Pay), its agency-now-pay-later payment product. The network spans roughly 25,000 vetted agencies across 27 countries. Breef is a hosted end-user SaaS product: it publishes no public developer program, API reference, SDK or webhook surface.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Breef the way a machine reads it — 2 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Breef scores 22.2/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Breef ships only an end-user SaaS product: its 483-URL sitemap carries no developer, API, docs or integrations page, no api./developer./docs./app./mcp.breef.com hostname resolves at all, and no npm, PyPI, RubyGems, crates.io or Packagist package exists — the only machine-readable contract on the estate is the customer application's own Django REST Framework schema at projects.breef.com/api/schema/, which negotiates application/vnd.oai.openapi but answers anonymous callers with 403 "Authentication credentials were not provided", so it is an internal app backend rather than a published developer program.
This is an honest zero, not a gap in our research. Breef does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Breef
Each block below is one kind of artifact we hold for Breef. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.

PLANSSecurity Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Breef, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
