Substack Newsletter Scraper
Pricing
from $1.00 / 1,000 saved post metadata
Substack newsletter scraper for metadata from known public RSS or Atom feeds. Get one stable row per unique item with titles, dates, authors, links, source IDs, and clear run outcomes. The Actor reads the feed only.
M09 final repair: fixed escaped schema patterns and UTC fractional-date parity, removed false truncation when the finite response exactly meets the cap, and bounded production resource handling without changing the 60-second deadline.
Preserved the v1 metadata fields, IDs, limits and explicit feed input. Added standard platform start pricing ($0.00071) with the row rate unchanged.
M09 maintenance refresh (2026-10-09): added a small no-input UI prefill while
preserving runtime defaults, refreshed Store/SEO copy and the README hero,
upgraded safe transitive dependency resolutions and pinned the remaining
basic-ftp fix through an exact override. Local acceptance is 38/38 with
zero production npm audit findings; Cloud candidate/canary evidence is
recorded separately in the M09 workflow closeout.
Closed post-Publish release 0.1.6 on 2026-09-18 UTC: independently
verified the public Store state, unchanged icon, $0.001 post-saved price,
exact source parity, one bounded public canary (zuyDNiC8orDJJmAyk, 20/20
rows/events), Dataset/KVS/output reconciliation and synchronized Git. No
source defect or replacement build was needed; rollback and maintenance
records are in docs/release/.
Completed the independent TZ-06 certification on merged-main build 0.1.6
(OBIvtWak9x1ovm2wc): fresh seven-run private matrix, exact live 20/200
proof, progressive Dataset writes, charge-boundary reconciliation and
synchronized metadata-only copy. After owner deletion of the five historical
builds and fresh inventory read-back, status is
CERTIFIED_READY_FOR_MANUAL_PUBLISH. Actor remains private, icon unchanged
and Publish untouched.
Completed TZ-05 private finalization with exact build 0.1.5
(bw5D8CLW3aabX7qrM): applied $0.001 post-saved PPE pricing with no
start fee, promoted the exact build to private latest/production, and
recorded final positive, charge-cap, production, empty, mixed and
20-feed large checks. Public visibility, icon and Publish remain owner-only.
Implemented the bounded public Substack RSS/Atom metadata reader.
Added exact-pinned TypeScript/Apify runtime dependencies, Docker packaging, Dataset/KVS adapters and the metadata-only output contract.
Added deterministic tests for URL/DNS safety, XML parsing, identity and date handling, limits, retries, redaction, cancellation and write/charge acknowledgement behavior.
Completed historical private technical acceptance on candidate 0.1.3, including
1,000-item deterministic reconciliation, near-limit public-feed evidence,
exact total-cap accounting and output/identity checks. The Actor remains
private and metadata-only.
Completed TZ-04 competitive validation and owner-reviewable publication preparation: current Top-10/Top-5 evidence, bounded paid comparisons, sanitized sample, Store copy, support, SEO, monitoring, rollback, pricing decision and release checklist. Its price recommendation was subsequently applied privately in TZ-05; no public setting or icon was applied.
