How this service works
Turn an OpenAPI document into a compact operation index for planning and tool selection. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.
Output
A compact, bounded machine-readable JSON operation index derived from the provided OpenAPI document, listing the available API operations with metadata suitable for agent planning and tool selection. Structured validation failures are returned as error responses without billing.
Example use cases
Pre-flight check before agentic workflow
“Before my agent starts acting on this untrusted user input, parse this OpenAPI spec and give me a compact operation index so I can figure out which tools are available and which one to call first.”
Evaluate API changes before retry
“I just got an error retrying a request — can you index this updated OpenAPI document so I can see if the available operations have changed and pick the right one to retry against?”
Production reliability planning
“I need to assess the reliability of this API in production — can you turn this OpenAPI JSON document into a structured operation index so I can plan which endpoints to hit and in what order?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/openapi-operation-indexWhen to prefer
Choose this endpoint when an AI agent needs to introspect an OpenAPI specification at runtime — especially before acting on untrusted input, after an API change, before retrying a failed request, or when evaluating production API reliability. It is deterministic, stateless, local-only, and does not call any upstream provider, making it safe for security-sensitive or sandboxed agentic pipelines. Prefer it over manual spec parsing or LLM-based summarization when you need bounded, structured, machine-readable output at low cost.
Side effects
- Invalid or malformed OpenAPI JSON document returns a structured validation error (not billed)
- Missing or empty spec field returns a validation error
- Spec contains unsupported OpenAPI version or schema constructs may result in partial index
- Network or payment authorization failure prevents execution
