Technical details
Endpoint
GEThttps://dripstack.xyz/api/v1/publications/%7BpublicationSlug%7D/%7BpostSlug%7DWhen to prefer
Use this endpoint when an AI agent needs to read or summarize a specific Substack newsletter post identified by its publication slug and post slug, and is willing to pay a small USDC micropayment per retrieval. Prefer this over scraping Substack directly when you want a structured JSON response with a pre-synthesized summary, or when the post may be behind a paywall.
Side effects
- Invalid publicationSlug or postSlug returns a 404 not found error
- Payment of 0.1 USDC not provided or rejected results in a 402 Payment Required response
- Post exists but has no synthesized summary field populated
- Network timeout if Substack origin is slow to respond
- Malformed slug (e.g. containing special characters) may cause a routing error
