What Was API World 2023?
API World 2023 was a developer and API conference held in Santa Clara, California, USA, from 24 to 26 October 2023. It brought together software engineers, API architects, product managers, and technology leaders to explore API design, integration patterns, and the software infrastructure connecting the modern internet, including Web3 and blockchain APIs. The official page sat on the API World site. It is a software development conference with a strong Web3 track rather than a pure crypto event.
APIs are the connective tissue of the internet, and Web3 has its own rapidly growing API layer. To follow tech and crypto gatherings, see CoinGabbar's crypto events calendar and our Web3 tech events list.
Key Themes at API World
The agenda spanned the full software API landscape:
- API design and architecture.
- Web3 and blockchain APIs.
- AI and LLM integration.
- Developer tools and infrastructure.
The Web3 track drew blockchain builders. Many guests also tracked broader blockchain events through CoinGabbar.
How Web3 APIs Are Growing in the United States
The United States is the world's largest developer ecosystem, and its API infrastructure powers much of the global internet, including Web3. As the US crypto landscape matured, with spot Bitcoin and Ethereum ETFs launching in 2024 and the GENIUS Act of 2025 establishing the first federal stablecoin framework, the demand for reliable, developer-friendly Web3 APIs has grown in step. Node providers, indexing services, wallet SDKs, and on-chain data APIs are now a substantial segment of the developer tooling market.
Silicon Valley's Santa Clara is the centre of that developer ecosystem, hosting the engineering talent and technology companies that build the API infrastructure underpinning both Web2 and Web3. For Web3 builders, the overlap with traditional API conferences matters: the same security, scalability, and design patterns that apply to Web2 APIs apply to blockchain infrastructure, and cross-pollination between communities advances both.

Impact of the Event on Web3 Development
A major developer conference in Silicon Valley advances Web3 infrastructure. It connects blockchain API builders with the broader software community. It spreads best practices across Web2 and Web3. And it grows the pool of developers comfortable with both paradigms. Each edition advances the Web3 developer stack.
Why Sponsors, Exhibitors and Projects Should Join
A developer conference reaches builders with shipping velocity. Strong fits include:
- Blockchain node and RPC providers: reach developers directly.
- On-chain indexing and data APIs: demo to builders.
- Wallet SDKs and account abstraction: onboard engineers.
- Smart contract and tooling platforms: find contributors.
- Web3 security firms: educate developers.

Why KOLs, Media and Influencers Attend
Developer infrastructure shapes the future of software. Creators meet the engineers building the tools that power both Web2 and Web3. Coverage can spread through the crypto press release network.
Why Builders and Participants Join
For Web3 developers, this conference bridges worlds. You learn from Web2 API best practices, meet node and indexing providers, and explore how AI is intersecting with on-chain development. Many leave with better tooling knowledge, new provider relationships, and a broader view of software architecture.

Glossary of Key Terms
- API: Application Programming Interface — a way for software systems to communicate.
- RPC: Remote Procedure Call — the standard way to query a blockchain node.
- Indexer: a service that reads blockchain data and makes it queryable via API.
- SDK: a Software Development Kit that helps developers build apps faster.
- Account abstraction: a Web3 design pattern that makes wallets behave more like web accounts.
