How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object containing a total count, source attribution (APIs.guru CC0 directory), a snapshot date, and an array of matching API records — each with an id, title, version, description, authentication notes, documentation URL, and OpenAPI specification URL. The metadata_only flag indicates no live execution is available; credentials_granted reflects payment status.
Example use cases
Discover APIs for a new integration
“I need to find public APIs related to e-commerce or product catalog data — can you search the API directory and show me up to 10 results with their descriptions?”
Explore authentication API options
“Search for APIs that deal with authentication or OAuth and return the top 5 so I can evaluate which one to integrate.”
Find geolocation data APIs
“Look up available public APIs for geolocation or IP address location and list their names, versions, and documentation URLs.”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/discovery/api-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover or enumerate public APIs by keyword from the APIs.guru directory — especially useful for developer research, integration planning, or automated API cataloging tasks. Prefer it over generic web search when you need structured, machine-readable API metadata including spec URLs and versioning. Not suitable for executing the discovered APIs directly.
Side effects
- Missing required 'q' query parameter returns a validation error
- Query string exceeding 200 characters is rejected
- Limit value outside 1–20 range is rejected
- No matching APIs found returns an empty results array with total:0
- Payment not processed (402) results in credentials_granted:false and no results
- Upstream APIs.guru directory unavailable causes a downstream error
