A side-by-side comparison of Loomal and Opper AI — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

Loomal

Freemium

Payments layer for agentic commerce — paywall any API, MCP tool, or store so AI agents can pay in USDC on Base per request.

Five-Line Paywall SDK: Wrap any Express, Hono, Next.js, or FastAPI handler with requirePayment to charge agents per call.
x402 Protocol Support: Uses HTTP 402 Payment Required as a real payment rail, so auth and payment happen in one round trip with no API keys.
USDC on Base Settlement: Payments settle on-chain in seconds; sellers keep custody of funds in their own wallet.
Per-Request Micropayments: Charge anywhere from a tenth of a cent to a dollar per call, enabling models the card networks cannot serve.
Signed Receipts: Every sale returns an Ed25519 receipt sellers can verify offline for provable, auditable revenue.
Hosted Endpoint Option: Paste JSON or upload a file and Loomal will host and paywall it at a URL agents can pay to hit.
Marketplace Discovery: A public marketplace lets agents discover paid APIs and MCP tools hosted through Loomal.
Broad Agent Compatibility: Works with any agent runtime that speaks x402 — Claude, GPT, Gemini, LangChain, CrewAI, MCP clients.

Monetizing an API: Turn a paid tier of a REST API into per-call micropayments that agents can buy without human onboarding.
Selling MCP Tools: Charge for premium MCP tools that agents in Claude Code, Cursor, or Windsurf install.
Data Vendor Distribution: Let agents buy scraped or curated datasets per query with no contracts or seats.
Hosted Content Paywalls: Sell access to a hosted JSON endpoint or uploaded file to agents that discover it in Loomal's marketplace.
Storefront Access (Coming): Add agentic checkout to a Shopify or WooCommerce store so AI shopping agents can transact directly.
SaaS Usage Billing: Bill agent traffic per action instead of per seat, aligning revenue with actual agent consumption.

EU-hosted AI gateway offering access to 300+ AI models through one OpenAI SDK-compatible, GDPR-compliant API.

Unified Model Gateway: One API and one key that routes calls to 300+ text, image, voice and video models across 30+ providers.
OpenAI SDK Compatibility: Drop-in base URL means existing OpenAI SDK code works unchanged against any model on the gateway.
EU Data Residency: Inference is hosted in the EU with a single sub-processor, so adding new models never triggers DPA amendments.
Intelligent Routing & Fallbacks: Per-request or org-level model selection with automatic fallback lists for zero-downtime model swaps.
Control Plane Guardrails: Optional Observe/Route/Steer/Guard/Comply modules add tracing, PII masking, content filtering and budget caps.
Agent CLI & Skills: Launch Claude Code, Codex, OpenCode and other agents against any Opper-hosted model or install auto-configuring skills.

GDPR-Compliant AI Products: European SaaS teams route all model calls through one EU sub-processor to keep customer data on-continent.
Multi-Model Experimentation: Product teams A/B test frontier and open models without changing SDKs or juggling many provider keys.
Cost & Latency Optimization: Ops teams use routing and fallbacks to prefer cheaper or faster providers per region while maintaining reliability.
Enterprise AI Governance: Compliance leads enforce model allowlists, PII masking, retention controls and budget caps across all agent traffic.
Agent Orchestration: Developers run coding and autonomous agents against a swappable backend model, with span-level tracing for debugging.
