# SiteCheck GSA Schedule Contractor Dossier

> SiteCheck GSA Schedule Contractor Dossier is a paid API for AI agents from api.companyrecords-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).

Returns GSA CALC+ data for a named contractor or keyword: contracts, labor categories with ceiling hourly rates, and price statistics (min/median/max/percentiles).

## Facts

- Endpoint: GET https://api.companyrecords-api.workers.dev/api/b2b/gsa-elibrary?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-24
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/sitecheck-gsa-schedule-contractor-dossier-c8dbc042
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_PW6A7GKogQdgKvWEhz5lu

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sitecheck-gsa-schedule-contractor-dossier-c8dbc042
```

Example prompt: Pull the GSA schedule dossier for Booz Allen Hamilton — I want their contracts, SINs, and the full ceiling rate stats (min, median, max, percentiles) across all their labor categories. Scan 3 pages of results.

## When to prefer this

Use this endpoint when you need structured GSA schedule and labor pricing data for a specific federal contractor or a service category — especially for proposal benchmarking, competitive intelligence, vendor due diligence, or market rate analysis within the US federal procurement ecosystem. Prefer this over manual GSA eBuy or CALC+ web searches when you need machine-readable stats and contract metadata in one call.

## Known failure modes

- No results returned if contractor name is misspelled or unknown to GSA CALC+
- Ceiling rates may not reflect actual invoiced prices — dossier explicitly flags this
- Truncated results if fewer pages than requested exist
- Rate data may be stale if GSA CALC+ index has not been updated recently
- Generic keyword searches may return mixed or unrelated contractors

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

A JSON object containing: matched vendor names, a list of GSA contracts (contract number, schedule, SINs, start/end dates, business size, labor category groupings), sampled labor category rows with ceiling prices and next-year escalation, aggregate price statistics (min, median, average, max, p10–p90 percentiles, count), education level distribution, worksite distribution (contractor vs customer facility), and a reference to the source GSA CALC+ API URL and timestamp.
