Comparison vs alternatives
Honest trade-offs. Melis doesn't win every category — here's when to use something else.
vs. Orbis (aggregator)
Orbis is the dominant x402 aggregator — ~40,800 calls/24h, thousands of bundled services, n8n integration, free tier. If you need breadth and want one endpoint for everything, Orbis is the right choice.
melis x402 Tools is a curated set of 16 services, not a marketplace. The value is: (a) charge-on-failure-safe across the fleet, (b) SSRF hardening and robots.txt enforcement baked into every service, (c) one MCP package that installs all 16 in seconds, (d) honest documentation with security audit history and on-chain wallet transparency.
Choose Orbis when: you need services beyond melis's 16, or want a free tier.
Choose melis when: you need provable charge-on-failure safety and SSRF hardening.
vs. StableEnrich
StableEnrich bundles Apollo, Clado, Exa, Firecrawl, Maps, Serper, Whitepages. It's strong for data enrichment and research (especially company data, contact data, and web search).
melis doesn't compete with Exa, Apollo, or Whitepages. The overlap is ScrapePay vs Firecrawl. Firecrawl is faster at scale; ScrapePay enforces robots.txt and is charge-on-failure-safe.
Choose StableEnrich when: you need Exa, Apollo, or Serper bundled together.
Choose melis when: you need robots.txt enforcement or charge-on-failure safety for scraping.
vs. Exa
Exa is a neural search engine over a high-quality indexed corpus. Excellent for finding semantically similar documents, recent news, and research. Requires a subscription.
ScrapePay hits the live web via Playwright — better for dynamic JS-rendered content, very fresh information (minutes old), and pages Exa hasn't indexed. MarkdownOpt + ScrapePay together cost $0.015; comparable Exa calls require a subscription plan.
Choose Exa when: you need corpus search, semantic similarity, or pre-indexed research quality.
Choose ScrapePay when: you need the live page, JS rendering, or no subscription dependency.
vs. BlockRun
BlockRun is an x402 AI model gateway — 55+ LLMs accessible via x402. Complementary to melis, not competing. Use BlockRun for the LLM call; use melis for the infrastructure around it (scraping input, validating output, notifying humans).
vs. agentsvc.io
agentsvc.io offers ~20 utility tools at $0.001–$0.008. Similar territory to melis. The overlap is real. Differentiators for melis: SSRF protection (confirmed via live security audit 2026-05-07), robots.txt enforcement on ScrapePay, charge-on-failure at SDK level, and the MCP wrapper for one-command install.
Unique services (no x402-native equivalent found)

|---|---|---|
| LinkSafe | Playwright sandbox + VirusTotal URL check | No other x402-native service confirms safety via sandbox + VirusTotal |
| LinkRisk | Heuristic URL risk profile | Lightweight pre-filter before LinkSafe; no x402-native equivalent found |
| PromptGuard | Prompt injection risk scoring | No x402-native prompt injection screen found (matches DataRobot #5 unmet need) |
| SchemaGate | JSON Schema validation for LLM output | No x402-native output validation found |
| CacheServe | URL fetch with server-side caching | No x402-native caching layer found |
