## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 719 tokens (~143/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

## MCP tools (5)

### `x402_get_categories` (~88 tokens)

List all 33 x402 service categories with aggregate stats: services
count, 24h volume, transaction count, real-volume %, and label
distribution. Use this to understand the shape of the x402 ecosystem
before drilling into specific services or wallets.
Free tier. No payment required. Returns wash-filtered data using the
same v2.0 algorithm as the paid endpoints.

### `x402_get_service` (~116 tokens)

Get the full detail record for one x402 service: name, description,
seller address, chain, price, 24h and total transaction stats, 30-day
daily volume time series, buyer-label distribution, and top buyers.
Use this to evaluate a single service's traffic composition.
Free tier. No payment required. Returns wash-filtered data using the
same v2.0 algorithm as the paid endpoints.

Input parameters:

- `service_id` (integer, required): Numeric x402 service id (visible in /services list and detail URLs).

### `x402_check_wash` (~173 tokens)

Get the aggregate wash-report dataset: 30-day total active buyers,
real-volume %, suspected_wash and self_test counts, full 8-label
distribution, 14-day wash percentage time series, and five anonymized
case studies (Service A through E) with pattern signals.

For per-address real-time wash analysis with full signal breakdown,
use the paid POST /api/v1/wash/check HTTP endpoint ($0.05 USDC) —
that endpoint speaks x402, agents pay and receive data in a single
HTTP round-trip.
Free tier. No payment required. Returns wash-filtered data using the
same v2.0 algorithm as the paid endpoints.

Input parameters:

- `address` (string): Optional wallet or seller address. When provided, the response includes a hint about the paid per-address endpoint.

### `x402_search_services` (~220 tokens)

Search the index of 36k+ x402 services with filters. Returns a
paginated list of matching services with their stats and label
mix. Use this to find services by topic, chain, or seller wallet.
Free tier. No payment required. Returns wash-filtered data using the
same v2.0 algorithm as the paid endpoints.

Input parameters:

- `category` (string): Filter to a single category slug (e.g. 'ai_inference', 'wallet_analytics').
- `chain` (string): Filter to one chain: 'base', 'solana', 'arbitrum', 'base-sepolia'.
- `page` (integer): 1-indexed page number.
- `page_size` (integer): Page size (max 200; default 24).
- `search` (string): Free-text match against name, description, or seller address.
- `sort` (string): Sort key: tx_24h | volume_24h | tx_total | price | real_pct | wash_pct | first_seen | alpha.

### `x402_get_trends` (~122 tokens)

Get the last-24-hour trends snapshot: new services count vs the
previous 24h, total transaction count, total USDC volume, active
buyer count, daily new-services bar (14 days), recent new services
(top 10), category volume movers, and hot services with traffic
surges (>= 100 24h tx and >= +50% growth). Refreshed every 5 min.
Free tier. No payment required. Returns wash-filtered data using the
same v2.0 algorithm as the paid endpoints.
