# x402lint Directory Full Export

> x402lint Directory Full Export is a paid API for AI agents from api.x402lint.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-18).

Returns the complete graded x402 directory as a single machine-readable export, including grade history, legitimacy signals, branding, verification status, and scan metadata for every listed origin (up to 10,000 records).

## 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 x402lint-directory-full-export-d935d791
```

Example prompt: Pull the full x402lint directory export so I have every listed origin with their protocol conformance grades, grade history, legitimacy signals, and scan counts all in one response.

## When to prefer this

Use this endpoint when you need the entire x402 directory in a single call rather than paginated or delta-based access. Prefer this over /v1/directory for bulk ingestion, offline analysis, or populating a data store. Use the delta endpoint (changed-since) instead if you have a recent snapshot and only need updates. Ideal for agents building routing tables, dashboards, or trust registries over the full x402 ecosystem.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Result set exceeds 10,000 records — response is truncated with truncated:true flag set
- Service unavailable or upstream scan database error — returns 5xx
- Malformed request parameters — returns 400 with error detail

## How this service works

Paid ($0.10). The entire graded directory in one machine-shaped response: every listed origin with grade, score, grade history, legitimacy signals, branding, verification and featured status — the same record shape as /v1/directory plus gradeHistory, firstSeenAt, and scanCount. Capped at 10,000 records (truncated:true if hit). Grades measure protocol conformance only and are NOT endorsements.

## Output

A JSON object containing up to 10,000 origin records, each with the same fields as /v1/directory plus gradeHistory, firstSeenAt, and scanCount. Each record includes protocol conformance grade, numeric score, legitimacy signals, branding data, verification status, and featured flag. A top-level truncated:true field is included if the 10,000-record cap was reached.
