# API Rescue - AI-Powered API Failure Detection & Fix Generator

> API Rescue - AI-Powered API Failure Detection & Fix Generator is a paid API for AI agents from rescue.agent.amnt.io, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-21).

Detects API failures, validates responses against schemas or baselines, diagnoses root causes, and proposes code fixes and regression tests in the requested language.

## Facts

- Endpoint: POST https://rescue.agent.amnt.io/api/agent/ax3lflores/api-rescue?utm_source=zero.xyz
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/api-rescue-ai-powered-api-failure-detection-fix-generator-6e818cec
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_epvheIgRhE8K3GjbzgnqP

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-rescue-ai-powered-api-failure-detection-fix-generator-6e818cec -d '<json body>'
```

Example prompt: My POST /orders API is returning a 422 status with a mismatched response body — can you detect what's wrong, validate the response against my expected schema, and give me a Python fix plus a regression test to prevent this from happening again?

## When to prefer this

Choose this endpoint when you need AI-assisted debugging specifically for API failures — detecting response schema mismatches, diagnosing HTTP error causes, and generating language-specific code fixes and regression tests in one call. Prefer this over generic code assistants when your primary need is API-layer debugging with test generation, especially in an agentic workflow that processes API health issues automatically.

## Known failure modes

- Vague or incomplete prompt may result in generic or unhelpful diagnosis
- Unsupported programming language may lead to generic pseudocode output
- Malformed or missing schema/baseline data in prompt reduces fix accuracy
- Network timeout if the AI inference takes too long
- Payment failure if USDC balance is insufficient for the $0.03 per-call fee

## How this service works

API Rescue - Detect API failures, validate responses against schema or baseline, diagnose causes, and propose code fixes and regression tests in the requested language.

## Output

Returns a structured text response containing: identified API failure causes, validation results showing where responses deviate from the schema or baseline, recommended code fixes in the requested programming language, and regression test code to prevent recurrence.
