How this service works
Turn an OpenAPI document into title, version, path counts, tags, and auth hints for $0.001 USDC. One single-fetch structured result, no API key.
Output
Returns a condensed overview of the OpenAPI document including the API title, version string, total count of paths, list of tags, and hints about authentication schemes used (e.g. Bearer, API key, OAuth2).
Example use cases
Route incoming API requests to correct handler
“I've got a bunch of OpenAPI specs from different vendors. Can you quickly summarize each one so I can figure out which APIs handle payments, which handle user management, and which ones use OAuth versus API keys?”
Validate API documentation before integration
“Before we add this third-party API to our platform, give me a quick overview—what's the API name, version, and authentication method? Also, how many endpoints does it expose and what are the main functional categories?”
Generate human-readable API capability reports
“Our team needs to understand what this API can do at a glance. Can you pull out the title, version, total endpoint count, what categories of operations it supports, and whether it uses bearer tokens or API keys for auth?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/openapi-summaryWhen to prefer
Use this endpoint when an agent needs a fast, structured digest of an OpenAPI specification without parsing the full document itself — ideal for API discovery pipelines, capability routing, or when presenting a human-readable snapshot of an API's structure. Prefer this over full spec parsing when you only need the top-level metadata and don't need individual endpoint schemas.
Side effects
- Invalid or malformed OpenAPI document returns a parsing error
- Document exceeds size limits returns an error
- Non-OpenAPI content submitted returns an unrecognized format error
- Network timeout if document URL is unreachable
- Missing required document body returns a 400 bad request
