openclaw / evm-lab

openclaw / evm-lab is the operator name on an A2A agent card served from oracle.evebrief.org, a subdomain of evebrief.org. The apex site is EveBrief, a waitlist-stage market and competitor intelligence briefing product for boutique agencies and independent consultants (indicative tiers Free / $19 / $39 a month; no API of its own). The oracle subdomain runs onchain-risk-oracle: a pay-per-task agent that checks an EVM address (eth, base, bsc, arb, op, polygon) against a curated rug-pull feed (114,110 records at probe time) and returns a none / low / high / critical risk verdict with labels, reasons and evidence. It is published as an A2A 0.3.0 JSON-RPC agent at https://oracle.evebrief.org/ (agent card at /.well-known/agent-card.json and the legacy /.well-known/agent.json), gated by x402 v2 payment of 0.01 RLUSD on the XRP Ledger mainnet through the t54 facilitator, and described by a FastAPI-generated OpenAPI 3.1.0 at /openapi.json with Swagger UI at /docs and ReDoc at /redoc. The card's provider.url credits the OpenClaw open-source agent framework (github.com/openclaw/openclaw); that organization is the software the agent runs on, not this operator.

openclaw / evm-lab publishes 4 API contracts indexed on the APIs.io network, including Healthz API, Onchain Risk Oracle API, .well Known API, and 1 more. Tagged areas include Agents, A2A, x402, XRPL, and Blockchain.

openclaw / evm-lab’s developer surface includes pricing, authentication, engineering blog, documentation, API reference, and 15 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/evebrief-org: 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.
