## 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**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1365 tokens (~151/item across 9 items; 9 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.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## MCP tools (9)

### `apihub_search` (~296 tokens)

Read-only. Searches onboarded APIHub services by free-text query, with optional category, price, and type filters. Returns up to 10 matches ranked by uptime and endpoint count, each with slug, description, endpoints array, min price in microdollars, provider name, and quality score. No authentication required. Use this when you need to find an API by capability; use apihub_list_services to browse without a query, apihub_search_external to include the external x402 catalog, or apihub_get_service when you already know a slug. Does not call any upstream API or debit credits.

Input parameters:

- `category` (string): Optional exact-match filter. Valid values: ai, data, search, finance, media, infra, communication, content, travel.
- `max_price_microdollars` (number): Optional upper bound on price per request in microdollars (1 USD = 1,000,000 microdollars, so 10000 = $0.01). Services whose cheapest endpoint exceeds this are excluded.
- `query` (string, required): Required free-text query matched against service name and description (case-insensitive substring match). Use 1-3 keywords describing the capability you want, e.g. 'weather' or 'stock price'.
- `type` (string): Optional filter. 'api' = standard REST APIs, 'content' = content gateways that proxy a fixed upstream URL.

### `apihub_list_services` (~158 tokens)

Read-only. Lists onboarded APIHub services alphabetically, returning each service's slug, name, description, category, provider, endpoint count, and lowest per-endpoint price in microdollars. No authentication required. Use this to browse the full onboarded catalog when you don't have a specific capability in mind; prefer apihub_search when filtering by query, category, or price. Does not include external x402 APIs (use apihub_search_external for those) and does not return endpoint-level details (use apihub_get_service for that).

Input parameters:

- `limit` (number): Optional max number of services to return. Default 20, minimum 1, hard cap 100. Values above 100 are clamped.

### `apihub_get_service` (~47 tokens)

Get full details for a specific API service including all endpoints, schemas, and pricing.

Input parameters:

- `service_slug` (string, required): The service slug (e.g., 'exchange-rates')

### `apihub_call` (~303 tokens)

Sends payment. Calls a paid endpoint on an onboarded APIHub service. Debits the endpoint's price from your credit balance and forwards the request to the upstream provider. Returns an object with the upstream response body, HTTP status, and credits_charged_microdollars. Requires a valid API key and sufficient credit balance; if balance is insufficient the call returns a 402 with payment requirements (use apihub_topup to add credits, apihub_balance to check). Use this for services already onboarded to APIHub (find slugs via apihub_search or apihub_list_services); use apihub_call_external for arbitrary x402 URLs not onboarded here, or apihub_read_content for content gateways.

Input parameters:

- `body` (string): Optional. Request body as a JSON string for POST/PUT. Ignored for GET/DELETE. The proxy forwards this verbatim with Content-Type: application/json.
- `endpoint_path` (string, required): Required. The endpoint path including any leading slash, e.g. '/latest/USD' or '/v1/forecast'. Get valid paths from apihub_get_service.
- `method` (string): Optional HTTP method, default GET. Must match the method declared on the endpoint or the request will fail.
- `service_slug` (string, required): Required. The service slug as returned by apihub_search or apihub_list_services, e.g. 'exchange-rates' or 'weather'.

### `apihub_search_external` (~94 tokens)

Search external x402-protected APIs (not operated by APIHub, but callable via credits). Returns listings with endpoint counts, prices, and on-chain activity.

Input parameters:

- `category` (string): Filter by category (ai, search, finance, media, other)
- `limit` (number): Max results (default 10, max 50)
- `query` (string): Search text matched against name/description

### `apihub_call_external` (~134 tokens)

Call an external x402-protected URL (any provider in the marketplace or any x402 API). APIHub pays the provider on your behalf using the platform wallet and debits your credit balance for the exact amount. No wallet or gas required.

Input parameters:

- `body`: Request body (object or string). Omit for GET.
- `headers` (object): Additional request headers. Do not set Authorization or X-PAYMENT - handled automatically.
- `method` (string): HTTP method (default POST)
- `url` (string, required): The full URL to call (e.g. https://hub.atxp.ai/...)

### `apihub_read_content` (~75 tokens)

Read web content through a paid content gateway. Returns clean, structured text extracted from the URL. Use this for content services (service_type = 'content').

Input parameters:

- `service_slug` (string, required): The content service slug
- `url` (string, required): The full URL to read (must match a verified domain on the service)

### `apihub_topup` (~101 tokens)

Purchase APIHub credits via x402 (USDC on Base). Returns payment instructions including a web URL for browser-based payment, a CLI command, and raw x402 requirements for agents with wallet support. Credits are added to your account instantly once payment confirms on-chain.

Input parameters:

- `amount_dollars` (number, required): Amount to top up in USD. Minimum $5.00, maximum $10,000 per call. Example: 10 for $10.

### `apihub_balance` (~100 tokens)

Read-only. Returns your current APIHub credit balance (in microdollars and USD), total lifetime spending (microdollars and USD), and total completed request count. Requires a valid API key. Use before apihub_call or apihub_call_external to confirm sufficient funds for a paid request, or periodically to audit usage. Does not modify state, send payments, or call upstream APIs; for top-ups use apihub_topup.
