Diagnose and fix ElevenLabs API errors by HTTP status code. An agent skill from jeremylongshore/tons-of-skills-marketplace.

  • Works in 3 steps: Quick Diagnostic → Map the Status Code to a Fix → Debug Checklist
  • Encountering ElevenLabs errors
  • SKILL.md covers Overview, Prerequisites, Instructions and Output, plus 4 more sections
  • Calls curl and jq; reaches api.elevenlabs.io; needs ELEVENLABS_API_KEY

What it does

Elevenlabs Common Errors is an agent skill from jeremylongshore/tons-of-skills-marketplace. Diagnose and fix ElevenLabs API errors by HTTP status code. Use when encountering ElevenLabs errors, debugging failed TTS/STS requests, or troubleshooting voice cloning and streaming issues. Trigger with "elevenlabs error", "fix elevenlabs", "elevenlabs not working", "debug elevenlabs", "elevenlabs 401", "elevenlabs 429", "elevenlabs 400".

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/error-reference.md`). Compatibility notes: Designed for Claude Code

It sits in Media & Creative, covering Text to speech and voice. It works with ElevenLabs. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Encountering ElevenLabs errors
  • Debugging failed TTS/STS requests
  • Troubleshooting voice cloning and streaming issues
  • With elevenlabs error

Example prompts

  • “elevenlabs error”
  • “fix elevenlabs”
  • “elevenlabs not working”
  • “/elevenlabs-common-errors”

Requirements

  • A credential in ELEVENLABS_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Bash(curl:*), Bash(node:*)

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Quick Diagnostic
  2. Map the Status Code to a Fix
  3. Debug Checklist

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(curl:*)
    • Bash(node:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.elevenlabs.io

    Also links to:

    • status.elevenlabs.io
    • help.elevenlabs.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • ELEVENLABS_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Elevenlabs Common Errors loads about 1.5k tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 518 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ElevenLabs Common Errors

Overview

Quick diagnostic reference for ElevenLabs API errors organized by HTTP status code: run the connectivity probe, map the observed status code to a fix, then confirm with the debug checklist. This file is the fast index; the full per-error catalog (payloads + code fixes for every status code) lives in references/error-reference.md.

Prerequisites

  • ElevenLabs SDK installed
  • API key configured (ELEVENLABS_API_KEY)
  • Access to error logs or console output

Instructions

Step 1: Quick Diagnostic

Run the connectivity probe to isolate auth from quota from request problems:

bash
# Test API connectivity and auth
curl -s -w "\nHTTP %{http_code}" \
  https://api.elevenlabs.io/v1/user \
  -H "xi-api-key: ${ELEVENLABS_API_KEY}"

# Check character quota
curl -s https://api.elevenlabs.io/v1/user \
  -H "xi-api-key: ${ELEVENLABS_API_KEY}" | \
  jq '.subscription | {tier, character_count, character_limit}'

# List available voices (confirms API access)
curl -s https://api.elevenlabs.io/v1/voices \
  -H "xi-api-key: ${ELEVENLABS_API_KEY}" | jq '.voices | length'
Step 2: Map the Status Code to a Fix

Match the HTTP status code (and the detail.status string in the response body) to its row below, then open the linked catalog entry for the exact payload and copy-paste fix:

Statusdetail.statusRoot causeFirst move
401invalid_api_keyKey missing/malformed/revokedRe-check ELEVENLABS_API_KEY, regenerate if needed
401quota_exceededMonthly character limit hitCheck usage, upgrade or enable usage-based billing
400voice_not_foundBad voice_id in pathGET /v1/voices to list valid IDs
400text_too_longTTS text > 5,000 charsChunk text with previous_text/next_text
400model_not_foundBad model_id stringUse an exact model ID (see catalog)
429too_many_concurrent_requestsOver plan concurrencyQueue requests to your plan limit
429system_busyElevenLabs under loadRetry with backoff (maxRetries)
422invalid_voice_sampleClone audio bad format/too shortMP3/WAV/M4A/FLAC, ≥30s, clean speech
—WebSocket fails silentlyMissing xi_api_key / eleven_v3 on WSSend key in first WS message, use eleven_flash_v2_5

Full payloads, causes, and fix snippets for every row: references/error-reference.md.

Step 3: Debug Checklist
  1. Verify API key: curl -s https://api.elevenlabs.io/v1/user -H "xi-api-key: $ELEVENLABS_API_KEY"
  2. Check quota: Look at character_count vs character_limit in the response
  3. Verify voice_id: GET /v1/voices to list valid IDs
  4. Check model_id: Must be an exact match (see catalog)
  5. Check request size: Text must be under 5,000 characters
  6. Check concurrency: Are you exceeding your plan's concurrent limit?
  7. Check ElevenLabs status: https://status.elevenlabs.io

Output

Working through this skill produces:

  • A resolved HTTP status code and detail.status string identifying the exact failure.
  • The applied fix (corrected key/quota, valid voice_id/model_id, chunked text, request queue, or WebSocket handshake correction).
  • A clean re-run of the Step 1 probe returning HTTP 200 from /v1/user and a non-zero voice count, confirming the request path is healthy.

Error Handling

HTTPErrorRetryableAction
400Bad requestNoFix request parameters
401Auth/quotaNoCheck key or upgrade plan
404Not foundNoVerify voice_id/model_id
422ValidationNoFix input data format
429Rate limitYesBackoff + queue requests
500+Server errorYesRetry with backoff

Examples

401 after key rotation — the probe returns HTTP 401 with invalid_api_key. The old key is still in the shell env:

bash
echo "${ELEVENLABS_API_KEY:0:8}..."   # confirms which key is loaded
# export the freshly generated key, then re-run the Step 1 probe → HTTP 200

429 under load — batch TTS returns too_many_concurrent_requests. Cap concurrency to the plan limit instead of firing all requests at once:

typescript
import PQueue from "p-queue";
const queue = new PQueue({ concurrency: 5 }); // Match your plan
await queue.add(() => client.textToSpeech.convert(voiceId, options));

400 on long input — a 7,000-character request returns text_too_long. Split it and preserve prosody across chunks:

typescript
const audio = await client.textToSpeech.convert(voiceId, {
  text: currentChunk,
  previous_text: previousChunk,  // Helps maintain flow
  next_text: nextChunk,          // Helps maintain flow
  model_id: "eleven_multilingual_v2",
});

See references/error-reference.md for the full payload and fix for every status code above.
