How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON response with a 'data' object containing the llms.txt content (a compressed machine-readable directory of available MCP servers, x402 APIs, and A2A agents), a 'status' field ('ok' on success), and an 'roi_proof' object showing the compression ratio percentage (e.g. 91.4%). The document is heavily compressed relative to raw content.
Example use cases
Discovering available MCP tools for a workflow
“Pull the full llms.txt catalog from the AgentDiet gateway so I can see which MCP servers are available before I decide which tools to use in my automation pipeline.”
Auditing x402 API offerings for agent spending
“Get the AgentDiet gateway's agent directory index so I can review which x402 APIs accept USDC payments and figure out which ones fit our budget for autonomous tasks.”
Bootstrapping a new AI agent's tool registry
“Fetch the AgentDiet MCP gateway's llms.txt so my new agent can load the full list of 31,000+ available servers and APIs it can call to complete user requests.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/llms-txt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover the full catalog of MCP-compatible tools, x402 APIs, or A2A agents available through the AgentDiet broker, especially in workflows where dynamic tool selection or capability enumeration is required before task execution. Prefer this over manually curated tool lists when you need broad coverage of 30,000+ servers in a single compressed fetch.
Side effects
- Payment not settled — x402 payment in USDC on Base required before content is served
- Invalid input schema — missing required 'type' or 'method' fields returns an error
- Network timeout — gateway unreachable or overloaded
- Stale index — directory may lag real-time server availability by some interval
- Malformed query parameter — non-string or missing 'url' param causes rejection
