Score API — "Is it worth it?"

The SaaSTweaks Score (deterministic 6-pillar 0–100), band, verdict and review URL for any published tool. 404 JSON for unscored slugs.

Score badge (SVG)

Embeddable badge — "SaaSTweaks Score 84 · STRONG BUY" in the band colour. Unknown slugs get a neutral "not yet scored" badge, never a broken image. Embed terms: link the badge back to the tool's review page.

Savings Arbitrage feed

The live arbitrage boards as one JSON document: startup credits founders pay past (the "$2M+ free-money pile", with heuristic eligibility gates), verified locked-savings deals (Score ≥ 60), and annual-billing spreads. Null gates mean "verify on the program page" — never assume.
