Stellar API Provider
Comparison
Compare Stellar API provider options across Horizon support, Soroban RPC, rate limits, analytics, monitoring, reliability, and pricing to find the best fit for your application.
How We Compare Providers
Choosing a Stellar API provider is not just about rate limits and pricing. The right provider depends on your technical requirements, team capacity, and product roadmap.
API Coverage
Which Stellar APIs are supported: Horizon REST, Soroban RPC, streaming, and historical data access.
Reliability
Uptime guarantees, rate limit handling, burst capacity, and behavior during network congestion.
Developer Experience
Onboarding speed, documentation quality, SDK support, and how fast you can go from signup to first request.
Value-Added Features
Analytics, monitoring, decoded transactions, smart contract tools, and other capabilities beyond raw API proxy.

Decision Guide
Use this guide to determine which option best fits your specific requirements and constraints.
Choose Public Stellar Endpoints If...
- - You are building a prototype or proof of concept
- - Your application has very low traffic (under 1,000 requests/day)
- - You do not need an uptime guarantee or SLA
- - You are comfortable handling rate limit errors in your code
Choose Self-Hosted Infrastructure If...
- - You have strict data residency requirements
- - Your team has experienced DevOps/SRE engineers available
- - You need unlimited throughput with zero external dependencies
- - You are already running Stellar Core for validation or anchoring
Choose a Generic Provider If...
- - You are building a multi-chain application and need a single vendor
- - You only need basic Horizon API proxy access (no analytics or Soroban)
- - Your primary chain is not Stellar but you need occasional Stellar data
Choose LumenQuery If...
- - You are building a Stellar-first application and need deep ecosystem support
- - You need both Horizon and Soroban RPC access from a single endpoint
- - You want built-in analytics, transaction monitoring, and decoded operations
- - You want to start free and scale as your application grows
- - You need features like natural language querying, whale alerts, or portfolio tracking

Frequently Asked Questions
What are the main Stellar API provider options?
The main options are: (1) the SDF-operated public Horizon and Soroban RPC endpoints, (2) self-hosting your own Horizon and Stellar Core instances, (3) generic blockchain API providers that include Stellar as one of many chains, and (4) Stellar-specialized providers like LumenQuery that focus exclusively on the Stellar ecosystem.
Is the public Stellar Horizon API suitable for production?
The SDF public Horizon endpoint is intended for development and testing. It has no SLA, variable rate limits, and no support channel. Most production applications eventually hit reliability or rate limit issues that require migrating to a managed provider or self-hosted infrastructure.
How much does it cost to self-host a Stellar Horizon node?
A production-grade Horizon instance requires a PostgreSQL database with significant storage (500GB+), a Stellar Core instance for ingestion, monitoring, and regular maintenance. Infrastructure costs typically range from $200-$500/month, plus engineering time for operations, upgrades, and troubleshooting.
What makes LumenQuery different from generic blockchain providers?
LumenQuery is built exclusively for the Stellar ecosystem. This means native support for both Horizon and Soroban RPC, Stellar-specific analytics (TPS, fee stats, token velocity), decoded transaction operations, smart contract exploration, and features like natural language querying that are tailored to Stellar data models.
Do generic blockchain API providers support Soroban?
Most generic providers have limited or no support for Soroban smart contracts. They typically offer basic Horizon proxy access but lack Soroban RPC endpoints, contract event streaming, storage state queries, and the specialized tooling needed for Soroban development.
How should I choose a Stellar API provider?
Consider your specific needs: rate limits and throughput requirements, whether you need Soroban RPC access, the importance of analytics and monitoring features, your budget, and the level of support you need. For most production applications, a Stellar-specialized provider offers the best balance of features, reliability, and cost.
