Berrer

Berrer runs BerrerGate (berrergate.com), an agent-native "tool and provider intelligence" service: an AI agent describes a task in natural language and BerrerGate maps it to agent-usable tools, APIs and provider categories, returns a free, cache-only procurement preview, and sells tightly bounded "decision packets" — evidence-backed shortlists of commercially cleared open-source implementations for observability, orchestration, scraping, analytics and browser automation — plus a paid Evidence Brief and a low-cost pay-per-call AI answer, all settled in USDC on Base through x402 with no account. The same surface is published three ways from api.berrergate.com: a 25-operation OpenAPI 3.1 contract at /openapi.json, an A2A agent card at /.well-known/agent-card.json with twelve skills (listed as Verified in the Global A2A Registry), and a remote MCP endpoint at /mcp declared in an MCP server.json manifest; discovery is rounded out by an x402 manifest, an AI Registry catalog, an llms.txt and a provider-written skill.md. The company states it is experimental, publishes no terms of service, no contact address and no pricing page.

Berrer publishes 8 API contracts indexed on the APIs.io network, including A2a API, Agent API, Research API, and 5 more. Tagged areas include Agents, Agentic Commerce, A2A, MCP, and x402.

Berrer’s developer surface includes pricing, documentation, authentication, and 23 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/.

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/berrergate-com: open an issue to ask a question, or submit a pull request to add artifacts.

Standards implemented 1

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.

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
