ChainAware.ai

ChainAware.ai is an AI-powered blockchain intelligence platform, operated by Decentral Tech OÜ (Estonia) with algorithms from the SmartCredit.io team, that scores wallets, tokens, smart contracts and ERC-8004 AI agents for fraud, rug-pull, credit and trust risk across eight blockchains (Ethereum, BNB Smart Chain, Polygon, Base, Solana, TON, Tron, HAQQ) using 23M+ behavioural wallet profiles. The same models are exposed three ways: a five-operation Enterprise REST API at enterprise.api.chainaware.ai (Swagger 2.0 published at swagger.chainaware.ai, x-api-key auth, Business/Enterprise subscriptions); a hosted MCP server at prediction.mcp.chainaware.ai/sse (14 tools, anonymous tools/list, MIT-licensed source, listed in the official MCP registry); and an A2A 0.3.0 agent card at api.chainaware.ai/.well-known/agent-card.json whose five skills are paid per call through x402 (USDC on Base, $0.15 per call) or with an API key.

ChainAware.ai publishes 5 API contracts indexed on the APIs.io network, including Behaviour Prediction API, Credit Score API, Fraud API, and 2 more. Tagged areas include Blockchain, Web3, DeFi, Fraud Prevention, and AML.

ChainAware.ai’s developer surface includes engineering blog, authentication, documentation, API reference, getting-started guide, support, GitHub presence, and 32 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/chainaware-ai: 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
