Helius (helius.dev): AI Search Readiness

Sector: Crypto & Web3 · Category: Solana RPC & Webhook APIs · Cohort Rank: #26 of 40 · Score: 61/100 (Grade C+)

Helius (helius.dev) scores 61/100 (Grade C+), ranking #26 of 40 unblocked developer platforms audited on 2026-11-14 UTC (-2.1 pts vs the 63.1/100 cohort mean). From Cloudflare’s edge, https://helius.dev/ responded in 95ms TTFB with 254 KB HTML across 8 <script> tags, exposes 11 Schema.org JSON-LD types (Organization, ImageObject, WebSite, WebPage, SpeakableSpecification), and permits 28/29 AI crawlers while blocking 1 (Bytespider). At the discovery layer, helius.dev currently serves /llms.txt (HTTP 200), /llms-full.txt (HTTP 200), /pricing.md (HTTP 200), and returns non-200 on /.well-known/mcp.json (HTTP 404), /.well-known/openapi.json (HTTP 404).

Scope & limits: Technical readiness assessment from Cloudflare edge probes on 2026-11-14 UTC; independent audit not affiliated with Helius. Technical readiness does not guarantee AI citations or sales.

3. Missing-Artifact Diffs & Remediation

/.well-known/ai.txt (currently HTTP 404): Publish machine discovery pointer indexing /llms.txt, /ai/summary.json, and agent tool manifests.
/.well-known/mcp.json (currently HTTP 404): Expose Model Context Protocol discovery card so Claude Code, Cursor, and MCP registries discover official tools.
/.well-known/openapi.json (currently HTTP 404): Serve OpenAPI 3.1 JSON contract for deterministic function-calling and WebMCP execution.
/ai/summary.json (currently HTTP 404): Serve structured JSON entity profile, product category, and canonical support endpoints.
/robots.txt (1 AI crawlers disallowed): Review whether search/citation bots (OAI-SearchBot, Claude-SearchBot, PerplexityBot) are unintentionally blocked alongside training crawlers.
