Curated API registry with implementation metadata builders need before shipping: auth style, tool-calling support, pricing hints, docs quality, and known integration gotchas.
6 APIs
OpenAI
Unified response endpoint for text, tools, and multimodal interactions.
Auth: api_key
Rate limits: Tier-based limits per model and account.
Pricing: Token-based pricing by model family.
Gotcha: Schema/tool definitions can drift across model upgrades; pin regression checks.
Anthropic
Claude model runtime with long-context reasoning and structured tool use.
Auth: api_key
Rate limits: Tiered request/token limits; throughput varies by model.
Pricing: Input/output token pricing varies by model size.
Gotcha: Tool argument formatting and stop reasons need strict parser handling.
OpenRouter
Multi-provider model routing API for fast experimentation and fallback.
Auth: api_key
Rate limits: Provider-dependent quotas plus account-level controls.
Pricing: Pass-through pricing plus routing overhead depending on model/provider.
Gotcha: Model availability and capabilities can shift by upstream provider.
Pinecone
Managed vector database for retrieval and long-term agent memory.
Auth: api_key
Rate limits: Index size and operation-based limits by plan.
Pricing: Usage and capacity based.
Gotcha: Index design and metadata filtering strategy directly impact latency.
LangChain
Tracing, eval, and observability tooling for LLM and agent workflows.
Auth: api_key
Rate limits: Event and trace ingestion limits by plan.
Pricing: Usage-based tracing/eval tiers.
Gotcha: Without consistent run metadata, comparisons become noisy quickly.
Browserbase
Cloud browser sessions for autonomous browsing and workflow automation.
Auth: api_key
Rate limits: Concurrent session quotas by plan.
Pricing: Session-minute based pricing.
Gotcha: Session warm-up and anti-bot behavior can distort benchmark timings.

Work at OpenAI is being transformed by agents, in every department. Across our entire company, people are using Codex to do work that is more complex, longer-running, and increasingly cross-functional. Our internal usage offers an early look at how agentic tools may reshape https://t.co/BwFTgBRfjZ
