Disclosed Labs Developer API

Build on the most complete corpus of RUO peptide data anywhere. We collect, structure, and lab-verify certificates of analysis from across the market — and now you can pull that data directly into your own apps, sites, and research.

The API is free. In exchange, we ask for a visible dofollow link to disclosedlabs.com wherever the data appears (see Getting started).

Our scoring — and the raw data behind it

The API now exposes both layers. Every vendor carries a scores block — our trust score (0–100), A–F grade, the recency-weighted trending variant, the transparency score, and the corpus rollups (COA count, avg purity, safety-panel coverage, lab-corroboration rate, forgery flags) plus the 0–100 component sub-scores. Labs carry a credibility score and grade. GET /api/v1/peptides/{slug}/stats returns our per-peptide rollup.

Want the published rankings? GET /api/v1/vendors?sort=trustScore&graded=true is the vendor trust leaderboard; GET /api/v1/labs?sort=credibilityScore&graded=true is the lab leaderboard — the exact order, scores, and tie-breaks shown on disclosedlabs.com.

Prefer to score it yourself? The raw data behind every rollup is still right there — the COAs, their test results, and anomaly flags at GET /api/v1/coas — so you can build whatever ranking or stats make sense for your project. Be creative.

Three layers of data

1. Peptide database — canonical peptides with aliases, category, legal status, molecular data, and research summaries. GET /api/v1/peptides

2. COA corpus — parsed certificates of analysis: purity, potency, identity tests (mass spec / FTIR / HPLC), safety panels (endotoxin, sterility, heavy metals), and raw anomaly flags. GET /api/v1/coas

3. Vendors & prices — vendor identity + transparency (domain, country, domain age, founded year, business entity, socials), our trust score + grade, and cross-vendor price comparison. Confirmed vendors can also write their own prices and deals. GET /api/v1/vendors, GET /api/v1/prices

Labs round out the picture with identity + credentials (country, ISO-17025 flag, full accreditation list, verify portal, logo) and our credibility score + grade: GET /api/v1/labs. Want a deeper roll-up than our scores block gives? Pull /coas?lab=… or /coas?vendor=… and aggregate yourself.

Built to last

• Versioned — everything lives under /api/v1/. Breaking changes ship as /api/v2/; v1 keeps working.
• Consistent — cursor pagination, a stable response envelope, and machine-readable error codes everywhere.
• Self-describing — a full OpenAPI 3.1 spec you can generate clients from.
