According to OpenAI on Twitter, users facing issues redeeming API credits should update to the latest version of Codex CLI by running 'npm i -g @openai/codex@latest' and then executing 'codex --free'. This update is essential for blockchain and crypto developers who rely on OpenAI APIs for smart contract automation, trading bot development, and AI-driven trading signals. Ensuring seamless API access minimizes operational disruptions for crypto traders and developers working with DeFi protocols. OpenAI also provides additional troubleshooting and integration guidance in their help center (source: OpenAI Twitter, May 18, 2025).

According to OpenAI (@OpenAI), Plus and Pro users who sign in to Codex CLI with ChatGPT can now redeem $5 and $50 in free API credits, respectively, over the next 30 days (source: OpenAI Twitter, May 17, 2025). This move is expected to increase developer engagement and drive usage of AI-powered applications, which often rely on blockchain and cryptocurrency payments for API access. Traders should watch for increased transaction volumes and potential price impact on tokens tied to AI and API ecosystems, such as Fetch.ai (FET) and Bittensor (TAO), as more developers leverage these credits to build and deploy decentralized solutions.
