# API Integration Readiness Scorer

> API Integration Readiness Scorer is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Scores how integration-ready an API looks by combining health, OpenAPI spec availability, and authentication surface hints into a single readiness signal.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-delx-ai-389f797b -d '<json body>'
```

Example prompt: Can you score how integration-ready the API at https://api.example.com is — I want to know if it has an OpenAPI spec, healthy endpoints, and solid auth before I commit to building against it?

## When to prefer this

Use this endpoint when you need a quick, structured signal on whether an external API is worth integrating — especially before committing engineering effort. Ideal for automated vendor evaluation pipelines, API marketplace due diligence, or agent workflows that discover and rank APIs. Prefer this over manual inspection when you need a scored, comparable output across multiple APIs.

## Known failure modes

- Target API URL is unreachable or returns errors — score may reflect low health
- No OpenAPI spec found at standard paths — OpenAPI signal scores low
- Auth surface cannot be determined — auth hints may be absent or ambiguous
- Invalid or malformed URL input — returns validation error
- Target API blocks automated probing — partial or degraded score returned

## How this service works

Score how ready an API is for agent integration using health, OpenAPI, auth hints, x402 signals, and login surface checks.

## Output

Returns a composite integration readiness score combining API health status, OpenAPI specification availability, and authentication surface signals, giving a structured verdict on how easy and safe the API is to integrate.
