How this service works
Extracts OpenGraph tags, description, keywords, and page header meta tags.
Output
Returns a JSON object containing the page title, meta description, Open Graph tags (og:title, og:description), a supported flag, a confidence level (e.g. 'high'), a data_as_of timestamp, optional warnings, and a disclaimer. The response indicates whether metadata was successfully extracted and how reliably it was parsed.
Example use cases
Link preview card generation
“Fetch the Open Graph title, description, and any og: tags from https://techcrunch.com/2025/01/15/ai-agents-explode so I can render a nice preview card for our newsletter.”
SEO metadata audit
“Read all the meta tags and page title from https://mystore.com/products/running-shoes and tell me what title, description, and OG data is currently set — I want to audit their SEO.”
Content scraping for enrichment pipeline
“I have this URL — https://blog.openai.com/introducing-gpt-5 — can you extract the page title, description, and confidence level that the metadata was successfully read?”
Technical details
Endpoint
POSThttps://codepulse-api.hahavoid0.workers.dev/web/metadataWhen to prefer
Choose this endpoint when you need to quickly extract structured metadata (title, description, OG tags) from a URL without setting up browser automation or a full scraping pipeline. It is ideal for building link preview cards, auditing SEO metadata, or enriching content databases with page descriptions. At $0.01 per call with no API key required (x402 USDC on Base), it is a good fit for lightweight, pay-per-use metadata lookups in agentic workflows.
Side effects
- URL is unreachable or returns a non-200 status — supported may be false or confidence may be 'low'
- Page uses heavy JavaScript rendering and meta tags are not present in static HTML — incomplete extraction
- Malformed or missing og: tags — output fields may be null or absent
- Rate limiting or bot-blocking by the target site — request may fail or return partial data
- Invalid URL format in the body — likely returns a validation error
