Locus product guide · Updated
Is there an OpenRouter for APIs?
Yes. The OpenRouter model, one account and one balance in front of many providers, exists for paid APIs and data too. Locus Pro is one option: one credit balance for thousands of APIs, called per use over MCP, CLI, or API. RapidAPI, x402 Bazaar, Composio, Eden AI, and ToolRoute each cover part of the same need.
What does OpenRouter do, and why do people want it for APIs?
OpenRouter puts many language models behind one API and one prepaid balance. You pay model prices without markup, plus a fee when you buy credits (5.5% by card, 5% in crypto). You never open an account with each model lab.
Agents hit the same wall with tools. A research agent may need web search, scraping, email lookup, and speech in one task. Each provider wants its own signup, key, plan, and invoice. People searching for an OpenRouter for APIs want that list to collapse into one account.
Which products offer one account for many APIs?
Several products do, and they solve different parts of the problem. Some sell calls from one balance. Some list APIs you still subscribe to one by one. Some connect the accounts you already own.
| Product | What it covers | How you pay | Signup or plan per provider? | Agent access |
|---|---|---|---|---|
| OpenRouter | Language models only | Prepaid credits at model prices, fee on credit purchases | No | OpenAI-compatible API |
| Locus Pro | Paid APIs and data: search, scraping, enrichment, media, LLMs | Prepaid credits, charged per call, price shown before the call | No | Hosted MCP, CLI, API |
| RapidAPI | Marketplace of third-party APIs | A pricing plan per API, monthly subscription plus overage | Yes, a plan for each paid API | REST with one RapidAPI key |
| x402 Bazaar | Catalog of x402 payment-gated services | Pay per request in USDC from your own wallet | No accounts, the wallet pays each call | Discovery API and MCP |
| Composio | Over 1,500 app toolkits with managed auth | Free up to 100,000 tool calls a month, Pro $29 a month plus $0.0003 per extra call | Usually yes, you connect your own app accounts | SDK and MCP |
| Eden AI | Over 500 AI models: LLM, OCR, speech, translation, vision | Pay as you go at provider prices, 5.5% fee on credit purchases | No | Unified REST API |
| ToolRoute | Registry of 87 tools behind one key | Free 100 requests a day, Pro $29 a month for 10,000 requests | No | One API endpoint |
What should you look for in an OpenRouter for APIs?
Look for five things. Each one removes a step your agent or your team would otherwise do by hand.
- One balance. Every call draws from the same prepaid funds, so there is one invoice and one place to top up.
- Prices before the call. The agent should see what a call costs before it runs, not after the monthly bill.
- No per-provider keys. If you still sign up with each vendor, you have a directory, not a router.
- MCP access. Agents in Claude Code, Cursor, Codex, and similar hosts find and call tools through MCP without custom glue code.
- Spending controls. Caps per call and per period stop a looping agent from draining the balance.
How does Locus Pro work as one key for all APIs?
You sign up once, add credits, and connect your agent. The agent searches the catalog, reads the price, and calls the endpoint. Locus holds the provider accounts, so you never see a provider key.
The catalog lists over 15,000 endpoints, including Exa, Tavily, Brave, Firecrawl, Parallel, Perplexity, Hunter, Apollo, ElevenLabs, and OpenRouter itself. Fixed-price calls show their credit cost up front. Variable-price calls return a quote first, and you can set a hard ceiling.
Prices are per endpoint, not a flat pass-through. Some match the direct price closely. Others cost more than going direct. Check the price in the catalog before you commit a high-volume workload.
Which option fits which job?
Pick by what you already have and what your agent needs to reach.
- You only need language models: OpenRouter.
- Your agent needs paid data and APIs from one balance, with no vendor signups: Locus Pro.
- You want a large API directory and do not mind a plan per API: RapidAPI.
- You run your own wallet and want to pay x402 services directly: x402 Bazaar.
- Your agent acts inside apps you already use, like Gmail, Slack, or GitHub: Composio.
- You want many AI model types, like OCR or translation, behind one API: Eden AI.
Frequently asked questions
Is OpenRouter itself an option for non-LLM APIs?
No. OpenRouter routes language model requests. It does not sell search, scraping, or data APIs. You can reach OpenRouter models through Locus Pro, but not the other way around.
Is one API key for all APIs less secure?
It moves the risk to one credential. That credential should have spending caps and be easy to revoke. With Locus Pro, MCP clients sign in with OAuth, and you can remove an agent without touching any provider account.
Do I pay more than going direct?
Sometimes. OpenRouter and Eden AI state provider prices plus a fee on credit purchases. Locus Pro prices each endpoint, and some cost more than the direct plan. You save the signups, keys, and minimum plans. Compare the per-call price for your heaviest endpoint.
What if the API I need is not in a catalog?
Then you still integrate it directly. No router covers every API. Search the catalog first. On Locus Pro, the agent can run a catalog search before it decides.
