# Strale API — HTTP Error Explainer

> Strale API — HTTP Error Explainer is a paid API for AI agents from api.strale.io, paid per call via x402, $0.054/call, status unknown (last checked 2026-09-13).

Takes an HTTP error code or message and returns a plain-language explanation of what it means and how to fix it, with optional context and language support

## Facts

- Endpoint: GET https://api.strale.io/x402/v2/error-explain
- Price: $0.054/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/strale-api-http-error-explainer-ad41b18a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_xy5l6cSZqlbcQv6a_wXlf

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 strale-api-http-error-explainer-ad41b18a
```

Example prompt: Can you explain what the HTTP 429 error means — I'm hitting it when calling a third-party API and I need to understand why it's happening and what I can do about it?

## When to prefer this

Choose this endpoint when an AI agent or developer tool needs a structured, auditable explanation of an HTTP error code or message — especially in multi-agent pipelines where traceability matters. Useful when you want explanations available in multiple languages or when you need cryptographic audit trails attached to diagnostics.

## Known failure modes

- Missing required 'error' query parameter returns a 400 Bad Request
- Unrecognized or malformed error string may return a generic explanation or null result
- Payment failure (insufficient USDC balance) blocks the call entirely
- Unsupported language value may fall back to English without warning

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

A plain-language explanation of the given HTTP error, including what the status code or message means, likely causes, and recommended remediation steps. Response is accompanied by an audit record with cryptographic chain hashing for traceability.
