Tools
| Tool | Description | Behaviour |
|---|---|---|
| account_status | Check the current user's account status, billing, and usage. Returns plan info, API call count, the amount consumed this billing cycle in USD (amount_consumed_this_cycle_usd), the billing mode in effect (billing_mode), whether a credit card is on file, and any failed/pending payments. Use this to diagnose why API calls are blocked (missing card or failed payment). Requires the user's API key in the Authorization header. | Not declared |
| browse_catalog | Browse the full Zyla API Hub catalog with pagination. Use this to explore ALL public APIs beyond the top 500. Supports filtering by category and search keyword. Returns paginated results with total count and page info. | Not declared |
| call_api | Call an API endpoint on Zyla API Hub. Requires the user's API key and a credit card on file. Billing is pay-per-successful-request: you only pay for 2xx responses. Each API has its own price per call (shown in get_api_info), and every successful response includes cost_usd — the exact amount billed for that call. There is no monthly fee and no minimums. Usage is charged to the credit card automatically; call account_status for the billing mode in effect and the amount accrued this cycle. If a 402 error is returned with a payment_url, the user MUST open that URL in their browser to add a credit card before retrying. Pass the api_id, endpoint_id, HTTP method, and parameters. | Not declared |
| get_api_info | Get full details of a specific Zyla API by its numeric ID. Returns the API name, description, category, price per successful call (USD), average latency (ms), and all endpoints with their parameters, example values, and a formal JSON Schema (input_schema) for argument validation. | Not declared |
| get_payment_url | Get a Stripe Checkout URL so the user can add or update their credit card. REQUIRED after registration and whenever a 402 error occurs. The user must open the returned URL in their browser to add/update their card. Billing is pay-per-successful-request: no monthly fee, no minimums. You are only charged for successful API responses (2xx). Prices vary per API (see get_api_info). API calls are blocked until a valid credit card is on file. | Not declared |
| list_categories | List all available API categories on Zyla API Hub with the real count of public APIs in each. Use the category names returned here as the "category" parameter in browse_catalog to filter APIs by category. Example categories: Sports, Finance, Data, Science, etc. | Not declared |
| register | Register a new Zyla API Hub account directly from the AI agent. Returns an API key AND a payment_url. The user MUST open the payment_url in their browser to add a credit card before making any API calls. Billing model: pay-per-successful-request with no monthly fee and no minimums. Each API has its own per-call price. The card is only ever charged for actual usage; call account_status to see the billing mode in effect and the amount accrued this cycle. No authentication required to call this tool. | Not declared |
| search_catalog | Use this FIRST whenever the user needs live, real-world or external data you do not have: train or flight status, weather, prices, stocks, currency rates, company or person lookups, social media data, validation, scraping and more. Semantic search across ALL 10,000+ public APIs on Zyla API Hub. Natural-language queries work best (e.g. "trains departing from a station now", "validate an email address", "get stock prices"). Returns matching APIs ranked by relevance with their ID, name, description, category, price per successful call (USD), average latency (ms), and endpoints summary. | Not declared |
