How this service works
Everyday tools for AI agents, paid per call with x402: image generation, web pages and documents to Markdown, speech to text, embeddings, translation, summaries, email checks, exchange rates, DNS and domain records.
Output
Returns a JSON object containing a new API key (prefixed with 'atb_'), the key's ID, the paid amount ($5 USD), a bonus amount ($0.50 USD), total credits added ($5.50), and instructions on how to check the balance. The key is used as a Bearer token on all subsequent Agent Toolbox and MCP calls.
Example use cases
Bootstrap a new agent with credits
“Set up Agent Toolbox access for my new AI agent — purchase $5 of credits via x402 and give me the Bearer API key so I can start making tool calls.”
Top up credits before a batch job
“Before I run my document-processing workflow, buy $5 of Agent Toolbox credits and return the API key so the agent can call the Markdown conversion and summarization tools.”
Onboard a new team member's agent
“I need to provision a fresh Agent Toolbox API key with $5 of credits for a new agent we're deploying — please purchase it now and share the key.”
