How to integrate Tavily AI Search with OpenClaw

Direct answer: To integrate Tavily AI Search with OpenClaw, treat Tavily as an external REST API: create an OpenClaw skill (installed/configured via ClawHub) that holds no long-lived secret state, store Tavily credentials (API key or OAuth client) in ClawHub-managed secrets, have the skill call Tavily’s HTTP endpoints to run queries and indexing operations (or accept webhooks from Tavily and validate their signatures), and push any stateful or long-running work (large document ingestion, retries, scheduling) to external infrastructure (worker queues, object storage, databases). Authenticate and authorize explicitly (API keys or OAuth tokens with correct scopes), log and surface API errors, and test with direct cURL/HTTP calls before wiring the skill into agents.

 

Overview  

  • Conceptual model: OpenClaw runs small, explicit skills/agents that make outbound API calls. Tavily is an external service you call via REST (or webhook callbacks).
  • Key responsibilities: ClawHub holds installation/configuration and secrets. The skill contains code that calls Tavily’s API. External systems handle durable state, heavy ingestion, and scheduled jobs.

 

Prerequisites  

  • Access to a Tavily account and API credentials (API key or OAuth client id/secret). If you don’t know the exact endpoint names for Tavily, use the vendor-provided docs to get base URLs and available endpoints.
  • ClawHub access to install and configure skills and to store secrets/environment variables for the skill runtime.
  • A place for durable storage and background processing (S3-compatible storage, a database, and a worker/queue system like RabbitMQ, SQS, or a managed job worker), if you plan to index large datasets or need retries.
  • Basic debugging tools: curl, HTTP client (Postman), and logs from the skill runtime (via whatever logging ClawHub exposes).

 

Authentication & Secrets  

  • API key model: Store the Tavily API key as a secret in ClawHub (environment variable). Ensure the skill reads it at runtime and sends it in the Authorization header (or as vendor docs require).
  • OAuth model: If Tavily requires OAuth, register your application with Tavily and configure redirect URLs as Tavily requires. Use ClawHub to store the client ID and secret. Implement the OAuth flow externally (web server) or implement a token exchange flow in a secure host — avoid embedding client secrets inside browser-executable code. Persist refresh tokens in a secure store external to the agent runtime if long-lived access is required.
  • Least privilege: Use the minimum scopes necessary for search and index operations. Rotate keys periodically and be prepared to revoke them via Tavily’s console if compromised.

 

Skill design & runtime behavior  

  • Keep skills stateless: The skill should perform request → call → response and not try to be a database. For indexing and large uploads, accept an instruction to schedule work and hand off to an external worker/job queue.
  • Timeouts: Keep API calls bounded with timeouts. If a query or an indexing job takes longer than the skill runtime allows, return an acknowledgement and continue asynchronous processing outside the agent.
  • Retries and backoff: Implement exponential backoff for transient failures (5xx, rate limits). Prefer external workers with durable queues for retry logic rather than retrying in-memory inside the agent for long periods.
  • Webhook handling: If Tafily emits webhooks (status of indexing, callbacks), host a small HTTPS endpoint in your external service to receive and validate signatures, then notify the OpenClaw agent (for example, via a stored job status that the agent can query) or emit events into your queue.

 

Implementing queries: example (Node.js)  

  • Below is a minimal, generic example of how a skill handler might call Tavily’s search endpoint. Replace TAVILY_BASE and path with Tavily’s real URLs and use the secret stored in ClawHub as TAVILY_API\_KEY.
const fetch = require('node-fetch');

async function runTavilySearch(query, apiKey) {
  const url = 'https://api.tavily.example/v1/search'; // <b>//</b> replace with Tavily's real search endpoint
  const body = { query }; // <b>//</b> payload shape depends on Tavily's API
  const res = await fetch(url, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${apiKey}`,
    },
    body: JSON.stringify(body),
    // <b>//</b> choose an appropriate timeout mechanism in real code
  });

  if (!res.ok) {
    const text = await res.text();
    throw new Error(`Tavily API error: ${res.status} ${text}`);
  }
  const json = await res.json();
  return json;
}

// <b>//</b> Example usage inside a skill runtime where process.env.TAVILY_API_KEY is set by ClawHub
// (Wrap in your skill handler code)

 

Implementing indexing / ingestion  

  • Small uploads: For few documents, the skill can POST documents directly to Tavily (if the API allows). Observe request size limits.
  • Large datasets: Use object storage (S3) and a worker process. The skill should create an ingestion job (e.g., call Tavily to start a job and pass an S3 URL), or upload in chunks using pre-signed URLs if Tavily supports them.
  • Durable jobs: Store job metadata (status, job id, file locations) in an external database so you can query status independent of the agent runtime. Webhooks from Tavily should update that database; the agent can query it when a user asks for job status.

 

Webhook security & validation  

  • Signature verification: If Tavily supports webhook signatures, validate the signature header (HMAC or similar) using the secret provided. Always check timestamp headers to prevent replay attacks.
  • Reject unsigned requests: Return a 401/403 for invalid signatures. Log and alert on unexpected events.

 

Testing & debugging checklist  

  • Test Tavily endpoints directly with curl or Postman first to confirm credentials, scopes, and payload shapes.
  • Verify the skill can read secrets from ClawHub (e.g., print a masked confirmation or try a harmless test call).
  • Check HTTP response bodies and headers for rate-limit info, error codes, and diagnostic fields from Tavily.
  • Enable structured logs in the skill runtime and capture request/response pairs (mask PII before storing logs).
  • When something fails, inspect: network connectivity, DNS, Authorization header value, token expiry/refresh, and HTTP status/response body. Reproduce failing calls with curl using the same credentials to isolate issues.

 

Observability, metrics, and production hardening  

  • Emit metrics: request rate, error rate, latency, and job statuses. Tie them to Datadog/Prometheus via your external infra or ClawHub logging if available.
  • Rate limiting: implement client-side throttling and honor Tavily’s rate-limit headers. Use a queue to smooth bursts.
  • Secrets management: rotate API keys, limit access to ClawHub secrets, and log key usage anomalies.
  • Auditability: persist job traces (who triggered the ingestion or search and when) in an external DB for compliance and debugging.

 

Example curl checks  

  • Use curl to confirm a simple query — substitute your real endpoint and API key.
curl -X POST 'https://api.tavily.example/v1/search' \
  -H "Authorization: Bearer TAVILY_API_KEY_GOES_HERE" \
  -H "Content-Type: application/json" \
  -d '{"query":"find the invoice for order 12345"}'

 

Common failure modes & what to check  

  • Authentication errors (401/403): Check API key spelling, token expiry, OAuth scopes, and that the key is correctly injected from ClawHub environment variables.
  • Bad request (400): Validate payload schema against Tavily docs; test with curl and examine response body for field-level errors.
  • Rate limits (429): Respect Retry-After headers, back off, and move heavy operations to background workers.
  • Timeouts / connectivity: Increase client timeout for valid long operations or move to asynchronous job model. Check VPC, outbound firewall rules, and DNS resolution.
  • Webhook issues: Ensure the webhook endpoint is publicly reachable, uses HTTPS, and validates signatures.

 

Operational pattern summary  

  • Short synchronous interactions: Use the OpenClaw skill to accept a user query, call Tavily synchronously, format the result, and return it.
  • Long-running work: Use the skill to accept the request, enqueue work for an external worker (upload to S3, create job record), and respond with an acknowledgement. Update job status via webhooks or polling.
  • Security & maintenance: Keep secrets in ClawHub, rotate keys, restrict scopes, and validate webhooks.

Troubleshooting Tavily AI Search and OpenClaw Integration

1

Why does ClawConnector return "401 Unauthorized" when configured with Tavily API key in ClawAuthToken?

 

Direct answer

 

ClawConnector returns 401 Unauthorized because the Tavily API key in ClawAuthToken is not being presented exactly as Tavily expects (wrong header/prefix, extra whitespace, expired/invalid key) or the OpenClaw runtime isn't loading the env var/token. Verify header name/format, token validity, and that the connector sends the value to the correct base URL and environment.

 

Steps to debug

 
  • Check env var: ensure ClawAuthToken is set in the runtime and visible to the agent.
  • Confirm header: Tavily may expect x-api-key vs Authorization: Bearer.
  • Test directly with curl or fetch and inspect response body/logs.
# // test the key and header format
curl -i -H "x-api-key: $ClawAuthToken" https://api.tavily.example/health
// // Node fetch example
fetch('https://api.tavily.example/endpoint',{headers:{'x-api-key':process.env.ClawAuthToken}})

How to fix vector dimension mismatch error in ClawIndex when storing Tavily embeddings (e.g. 1536 dims)?

Direct answer: Ensure the vector size stored in ClawIndex matches the Tavily embedding dimension (1536). Either recreate/configure the index with dimension=1536, or transform each embedding to 1536 floats (truncate, pad with zeros, or re-embed). Verify the Tavily response, your env vars, and reindex after fixing.

 

Step-by-step fix

 

Practical checks and actions:

  • Verify embedding length from Tavily before storing.
  • Configure ClawIndex schema to 1536 dims or transform vectors to that size.
  • Reindex if schema changed and inspect logs/API responses.
# verify and fix embedding length
def fix_embedding(vec, target=1536):
    // truncate or pad with zeros
    if len(vec) > target:
        return vec[:target]
    if len(vec) < target:
        return vec + [0.0] * (target - len(vec))
    return vec

# usage before storing
emb = get_tavily_embedding(text)  // returns list[float]
emb = fix_embedding(emb, 1536)
store_vector(id, emb)

3

Why do metadata fields (title, url, tags) disappear after ClawPipeline ingest from Tavily document payload?

 

Direct answer

 

The metadata is being lost because the ClawPipeline ingest step is transforming or replacing the Tavily document payload without copying the payload's title, url, and tags into the pipeline's output schema. In practice this happens when field names are nested/renamed, omitted by a mapping/transform, or overwritten by a later processing stage.

  • Inspect the raw Tavily JSON to confirm where metadata lives (top-level vs nested).
  • Check the ingest mapping/transform in the skill or pipeline that consumes Tavily — that's where fields get dropped.
  • Confirm post-ingest object in logs or API response to see which stage removed them.

Example payload pattern to preserve:

{ 
// content for ingestion
"content":"...",
// preserve metadata explicitly
"metadata": { "title":"My Title", "url":"https://...", "tags":["a","b"] }
}

How to prevent duplicate or missing updates in ClawSyncJob when Tavily webhook triggers ClawWebhook?

Direct answer: Make the ClawWebhook-to-ClawSyncJob flow idempotent and verifiable — validate the Tavily signature, extract a stable event_id/version, persist an enqueue record (or lock) in an external store, immediately ack the webhook, and have ClawSyncJob check that store (or use an upsert with version checks and a unique constraint) before applying updates. Use short distributed locks to prevent concurrent processing and compare versions/timestamps to avoid out-of-order misses.

 

Implementation pattern

 

Practical steps:

  • Validate signature to avoid forged retries.
  • Deduplicate on event_id before enqueue using a DB unique key or Redis SETNX.
  • Ack quickly and enqueue; don’t do long work in the webhook handler.
  • ClawSyncJob must be idempotent: check processed flag or do INSERT ... ON CONFLICT ... WHERE version < EXCLUDED.version.
  • Use locks for concurrent workers and record processed timestamps to handle out-of-order delivery.
// express webhook handler
app.post('/claw/webhook', async (req,res)=>{
  // validate signature
  const evt = req.body;
  const id = evt.id;
  // dedupe: Redis SETNX
  const ok = await redis.set(id,'1','NX','EX',60);
  if(!ok) return res.status(200).send('duplicate');
  await queue.add({id,evt});
  res.status(200).send('ok');
});

// worker
queue.process(async job=>{
  const {id,evt}=job.data;
  // upsert with version check (Postgres)
  await db.query(
    `INSERT INTO events(id,version,status) VALUES($1,$2,'processed')
     ON CONFLICT (id) DO UPDATE SET version=EXCLUDED.version,status='processed'
     WHERE events.version < EXCLUDED.version`, [id, evt.version]
  );
});
