firecrawl agent

AI-powered autonomous extraction. The agent navigates sites and extracts structured data (takes 2-5 minutes).

Before starting autonomous extraction for structured records or listings, check firecrawl search alexandria '<data you need>' for a ready-made workflow or data provider. Inspect a matching contract with firecrawl list <provider> <capability> --pretty and execute with firecrawl scrape --alexandria <provider>/<capability> --options '<input JSON>' if it covers the task. Use the exact provider, capability, and input fields from that contract. Continue with Agent when no suitable tool exists or the task requires autonomous navigation.

Quick start

# Extract structured data
firecrawl agent "extract all pricing tiers" --wait --json -o .firecrawl/pricing.json

# With a JSON schema for structured output
firecrawl agent "extract products" --schema '{"type":"object","properties":{"name":{"type":"string"},"price":{"type":"number"}}}' --wait --json -o .firecrawl/products.json

# Focus on specific pages
firecrawl agent "get feature list" --urls "<url>" --wait --json -o .firecrawl/features.json

Run firecrawl agent --help for the full option list.

Done when: the output file contains valid JSON answering the request — or a job ID was intentionally returned for later polling.

Job IDs

Omitting --wait returns a job ID. A UUID positional argument is auto-detected as a status check:

# Check once (equivalent to adding --status)
firecrawl agent "<job-id>"

# Wait on an existing job, polling every 10 seconds for up to 5 minutes
firecrawl agent "<job-id>" --wait --poll-interval 10 --timeout 300

# Cancel an active job
firecrawl agent "<job-id>" --cancel

Tips

Use --wait for inline results; omit it only when you want a job ID to poll later (see Job IDs).
Use --schema for predictable, structured output — otherwise the agent returns freeform data.
Agent runs consume more credits than simple scrapes. Use --max-credits to cap spending.
For simple single-page extraction, prefer scrape — it's faster and cheaper.

Alexandria session feedback

To report an Alexandria session outcome or a provider/capability gap, use firecrawl alexandria feedback --rating good|partial|bad --url <website> --requested-functionality '<what was needed>' --rationale '<what happened>' --json. Use observed results in the rationale. No job ID is needed; this session feedback has no job-age deadline and no credit refund. Optional --provider-feedback and --capability-feedback JSON arrays describe specific gaps; inspect firecrawl alexandria feedback --help for their fields. Use the capability issue missing_capability when a provider exists but lacks the needed capability, and new_capability_request (with requestedFunctionality) to ask for one.
