Our Mission

We believe developers and AI agents should have access to powerful, reliable, and affordable data APIs that accelerate building better applications and intelligent workflows. Our mission is to provide high-quality API services that are easy to integrate — whether you're calling from application code, an LLM tool function, or an autonomous agent framework.

Built for AI Agents

● agent integration

All API Pick endpoints are simple JSON REST APIs — straightforward to expose as tools for any LLM or agent framework:

LLM Tool Calling

Compatible with OpenAI function calling, Claude tool use, Gemini function declarations, and any model that supports structured tool calls.

Agent Frameworks

Easily wrapped as LangChain tools, CrewAI actions, AutoGen functions, or custom MCP server endpoints.

Workflow Automation

Drop into n8n, Zapier, or Make as HTTP nodes to enrich data at scale inside automated pipelines.

Predictable Responses

Consistent JSON schema, well-defined error codes, and deterministic output make parsing trivial for automated consumers.

Why Choose Us

Credit-Based Pricing

Transparent pay-per-use pricing with free credits to get started. No subscriptions or hidden fees. Credits are only consumed on successful responses — ideal for agent retry logic.

Privacy Focused

We don't store your query data. All requests are processed securely and discarded immediately, making us safe to use in privacy-sensitive AI workflows.

Developer & Agent Friendly

Simple REST endpoints with structured JSON responses. No SDKs required — any HTTP client, LLM framework, or automation tool can call our APIs out of the box.

Reliable Infrastructure

Deployed on Vercel edge infrastructure for low-latency responses globally. Real-time results with no caching delays — essential for synchronous agent tool calls.
