Artem / A2A Sandbox

Artem / A2A Sandbox is a one-operator agent-commerce sandbox that runs a paid "Sandbox Contractor Agent" at a2a.elonsusk.com: an Agent2Agent (A2A) JSON-RPC agent selling 28 skills — keyless developer utilities (JSON/YAML/CSV conversion, hashing incl. keccak256, base64/hex/base58, JWT decode, UUID, semver, epoch), on-chain data reads (EVM and Solana balances, ERC-20 metadata, gas price, transaction status, SPL supply) and security scans (MCP tool-manifest risk, EVM contract bytecode signals) — plus model-backed code review, code generation and inference sold quote-first. Every skill is payable per call over the x402 v2 HTTP payment protocol (HTTP 402 + PAYMENT-REQUIRED challenge, USDC on Base or Solana, from $0.001) at POST /x402/{skill}, or through a classic multi-chain crypto invoice (SOL, USDC, ETH, BTC) on the REST task API. The same FastAPI origin publishes an OpenAPI 3.1.0 contract at /openapi.json with Swagger UI at /docs, an A2A agent card at /.well-known/agent-card.json, an x402 discovery document at /.well-known/x402.json, and live health and revenue-metrics endpoints. The registrable domain elonsusk.com itself serves no website (TLS refused, HTTP 401); the a2a subdomain is the whole public surface.

Artem / A2A Sandbox publishes 13 API contracts indexed on the APIs.io network, including A2a API, A2A Autonomous Trader Agent API, Health API, and 10 more. Tagged areas include Agents, Agentic Commerce, A2A, x402, and Developer Tools.

Artem / A2A Sandbox’s developer surface includes documentation, API reference, pricing, authentication, and 17 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-10-09 · rubric v0.23.0
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/elonsusk-com: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →

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
