8. Hiring Signals
The cleanest sources in this entire category — all free, no auth, public, stable:
- Greenhouse Job Board API — per-customer, fully public per
clientname. 5/5 viability. - Lever Postings API —
/v0/postings/{clientname}?mode=json. Free. - Ashby Job Postings API — Newest of three. Schema occasionally adjusts.
- Workable Public Jobs Feed —
/api/v1/widget/accounts/{clientname}. Free.
Aggregators and gated:
- LinkedIn Jobs — No official API; high-risk in 2026. Tier-D.
- Indeed APIs — Publisher Jobs API deprecated; only Job Sync / Sponsored Jobs APIs (partner programs). Tier-D.
- Glassdoor — Enterprise partners only since 2024. Same parent as Indeed (Recruit Holdings). Tier-C/D.
- TheirStack Job Postings API — $59-169/mo (same vendor as tech-stack product). Tier-A.
- JobsPikr — ~$500-2k+/mo; 70k+ employer career sites, 50+ countries. Tier-B.
- Diffbot KG (hiring view) — Tier-B.
9. Funding / M&A
- SEC EDGAR APIs — Free, 10 req/sec. Form D = US private placement signals (filed within 15 days of first sale). Parse XML/HTML for issuer + amount + signatories. Tier-A. Already in finance agent.
- sec-api.io — $69/mo for pre-parsed EDGAR incl. Form D as structured JSON. Saves weeks of XBRL work. Tier-A.
Recommended "Tier Zero" build set for Vivly
Ship these first — cheapest, most stable, highest-leverage:
- Greenhouse / Lever / Ashby / Workable job board APIs (free, no auth) — hiring signal backbone.
- SEC EDGAR + sec-api.io (free / $69/mo) — Form D = real-time private funding signals.
- YC directory mirror (free, daily) — startup discovery.
- Hunter.io ($34/mo) — clean email discovery.
- PDL Pro ($98/mo) — best dev DX for person/company enrichment.
- TheirStack ($59-169/mo) — modern tech-stack + hiring intent.
- Product Hunt v2 (free) — launch signals.
- Apple iTunes Search (free).
- Shopify / BigCommerce / WooCommerce / Etsy / eBay APIs (free, per-store OAuth).
- Keepa (€49/mo) — Amazon price history.
Total: ~$500/mo of API spend to cover ~80% of the company-intel surface. Crunchbase Pro ($99/mo) optional 11th if named-investor and round-level data without enterprise commitment is needed.
Cross-Cutting Legal Findings
LinkedIn-derived data is high-risk in 2026. Proxycurl shut down July 2026 after LinkedIn sued. hiQ v. LinkedIn (CFAA) does not protect commercial resale, fake accounts, or scraping behind auth. Coresignal, Bright Data, ContactOut all carry residual risk.
GDPR / DPDP: Public availability is not a lawful basis. Vivly must establish lawful basis, opt-out, retention rules, DSAR handling for any EU/India personal data. Cognism and FullContact are most defensible.
The post-Clearbit/post-Proxycurl world: Two most-popular enrichment APIs of 2020-24 are effectively gone. Design enrichment abstractions so the underlying provider is swappable.
Glassdoor closed, Indeed Publisher dead, AngelList API never returned. All three are scrape-only or aggregator-only as of 2026.
Amazon SP-API now has a $1,400/yr developer fee (Jan 2026). PA-API v5 retires May 15, 2026 — migration to Creators API needed.
