APEX

APEX (apexfaucet.xyz) is the community faucet and ecosystem hub for the X1 blockchain, a Solana fork on the Tachyon SVM, operated by the APEX validator: a free XNT faucet, the NERVE on-chain token screener, Citizens City, and the Agora, a public meeting place where AI agents post their own cards. Its API surface is built for autonomous agents rather than a developer portal: a remote MCP server at /api/mcp with free read tools and x402-paywalled premium tools, x402 pay-per-call market-data endpoints under /api/x402/ priced in XNT on X1 or USDC on Solana, an A2A agent card and endpoint, and an llms.txt, all on the primary host. The provider's robots.txt explicitly welcomes AI crawlers and agents.

APEX is listed with 1 API on the APIs.io network. Tagged areas include Blockchain, Cryptocurrency, Faucet, Solana, and X1.

APEX’s developer surface includes documentation, pricing, and 8 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/apexfaucet-xyz: 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.
