Green Helix

Green Helix Consulting, LLC builds infrastructure for autonomous AI-agent commerce. Its A2A Commerce Gateway (api.greenhelix.net, v1.4.10) is a single REST API of 137 tools across 16 services: per-agent wallets and metered billing, authorize-then-capture payment intents, standard and performance-gated escrow, subscriptions and split payments, Ed25519 cryptographic agent identity with verifiable claims and reputation, a service marketplace with matching and ratings, composite trust scoring and SLA checks, end-to-end encrypted agent messaging with price negotiation, dispute resolution, HMAC-signed webhooks and an event bus, plus Stripe, GitHub and PostgreSQL connectors. It publishes an OpenAPI 3.1 contract, a machine-readable tool and tier catalog, an A2A agent card, an ai-plugin.json, Python and TypeScript SDKs, a local MCP server, and a sandbox that resets on every deploy. Errors are RFC 9457, rate limits are signaled in headers, and x402 payment proofs are accepted as an alternative to API keys.

Green Helix publishes 22 API contracts indexed on the APIs.io network, including Batch API, Billing API, Checkout API, and 19 more. Tagged areas include Agents, Agentic Commerce, Payments, Escrow, and Billing.

The Green Helix catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Green Helix’s developer surface includes authentication, documentation, getting-started guide, API reference, GitHub presence, pricing, changelog, and 26 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/greenhelix-net: open an issue to ask a question, or submit a pull request to add artifacts.
