[ 03 ]

Composable building blocks.

Each endpoint is a single tool function — JSON in, JSON out. Snap them together inside agents, workflows, and RAG pipelines.

  1. 01

    Spec

    ::spec

    Pick endpoints from the catalog. Each one ships with an OpenAPI schema and a function-calling signature.

  2. 02

    Compose

    ::compose

    Wire endpoints into LangChain, OpenAI tools, or n8n nodes. No glue code, no scraping infra.

  3. 03

    Ship

    ::ship

    Deploy with predictable per-call pricing. Watch credits and latency from the dashboard.

[ 04 ]AI Agent Integration

Built for AI Agents & LLM Workflows

All endpoints are simple JSON REST APIs — easy to wire up as tools for OpenAI function calling, LangChain agents, Claude tool use, or any autonomous agent framework.

LLM Tool Calling

OpenAI / Claude / Gemini

Define any endpoint as a tool function. The agent autonomously decides when to call it and passes structured JSON arguments.

Workflow Automation

n8n / Zapier / Make

Drop in as an HTTP node in any automation workflow. Enrich leads, validate contacts, and research companies at scale.

Agent Frameworks

LangChain / CrewAI / AutoGen

Wrap any endpoint as a LangChain tool or CrewAI action. Predictable JSON responses make parsing straightforward for agents.

Frequently Asked Questions

What is API Pick?

API Pick is a curated collection of REST APIs purpose-built for builders and AI agents — real-time web search, content extraction, structured data lookups, and contact enrichment. Every endpoint is JSON-in / JSON-out with simple auth and credit-based pricing.

Are API Pick APIs free?

Every new account gets 100 free credits with no credit card. After that, credit packs start at $5 for 5,000 credits and credits never expire.

How does credit-based pricing work?

Each endpoint has a fixed credit cost per call (Web Search: 15, URL Extract: 2 per URL, Email Validator: 1, etc.). Credits are only deducted on successful HTTP 200 responses — failed retries are free.

Which AI agent frameworks does API Pick support?

OpenAI Assistants, Anthropic Claude tool use, Google Gemini, LangChain, LlamaIndex, CrewAI, AutoGen, n8n, Zapier, and any platform that can make an HTTP call with an API-key header.

How do I add an API Pick endpoint as a tool to my agent?

Each endpoint exposes a tool-schema route (e.g. GET /api/search/web/tool-schema) that returns ready-to-paste OpenAI function and Claude tool use definitions. No hand-writing JSON schemas.
