Abstract API MCP by usefulapi missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 14

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

abstractapi

abstractapi_calculate_vat

Work out the VAT-compliant price for an amount in a country: the amounts without and with VAT, the VAT amount and the rate. Set is_vat_incl to true for the reverse calculation (the amount already contains VAT). VAT Validation API. Spends 1 credit of your VAT Validation plan per request (a failed request counts too); needs the VAT Validation API key.

abstractapi_convert_currency

Convert an amount from a base currency to one target currency, at the latest rate or at the rate of a past date. Exchange Rates API. Spends 1 credit of your Exchange Rates plan per request (a failed request counts too); needs the Exchange Rates API key.

abstractapi_convert_time

Convert a date and time from one location to another (places, coordinates or IP addresses). Without base_datetime the current time is converted. Timezone API. Spends 1 credit of your Timezone plan per request (a failed request counts too); needs the Timezone API key.

abstractapi_enrich_company

Firmographic data for a company web domain: name, description, logo, address, industry (SIC/NAICS), employee and revenue ranges, contacts, social profiles, technologies. Company Enrichment API. Spends 1 credit of your Company Enrichment plan per request (a failed request counts too); needs the Company Enrichment API key.

abstractapi_get_current_time

The current local date, time and timezone (name, abbreviation, GMT offset, daylight saving) of a place, coordinates or IP address. Timezone API. Spends 1 credit of your Timezone plan per request (a failed request counts too); needs the Timezone API key.

abstractapi_get_exchange_rates

Latest foreign-exchange and cryptocurrency rates for a base currency against one or more targets (all supported currencies if none is given). Exchange Rates API. Spends 1 credit of your Exchange Rates plan per request (a failed request counts too); needs the Exchange Rates API key.

abstractapi_get_historical_rates

Exchange rates of a base currency on a past date. Abstract lists this endpoint as closed beta: a key may be refused (HTTP 401/403) until Abstract enables it. Exchange Rates API. Spends 1 credit of your Exchange Rates plan per request (a failed request counts too); needs the Exchange Rates API key.

abstractapi_get_holidays

Public, local and religious holidays of a country for a date, a month or a year. Free Abstract plans require year, month and day together; paid plans default missing values to today. Public Holidays API. Spends 1 credit of your Public Holidays plan per request (a failed request counts too); needs the Public Holidays API key.

abstractapi_list_vat_rates

The latest VAT rates of one country: the standard rate and each reduced-rate category with its description. VAT Validation API. Abstract answers this endpoint without checking the key and may not count it as a credit; this tool still needs the VAT API key.

abstractapi_lookup_ip

Geolocation and security intelligence for one IPv4 or IPv6 address: VPN/proxy/Tor/hosting/abuse flags, ASN, company, location, timezone, flag and currency. IP Intelligence API. An explicit ip_address is required (without one Abstract would look up the caller's own address, which here is this server's). Spends 1 credit of your IP Intelligence plan per request (a failed request counts too); needs the IP Intelligence API key.

abstractapi_lookup_phone

Validate and enrich one phone number: format, carrier, line type (mobile, landline, VoIP), location, line status, risk and known breaches. Phone Intelligence API. Spends 1 credit of your Phone Intelligence plan per request (a failed request counts too); needs the Phone Intelligence API key.

abstractapi_validate_email

Check one email address: deliverability (format, MX, SMTP), quality score, free/disposable/role/catch-all flags, sender details and known data breaches. Email Reputation API. Spends 1 credit of your Email Reputation plan per request (a failed request counts too); needs the Email Reputation API key.

abstractapi_validate_iban

Check the structure and check digits of one International Bank Account Number. It does not prove that the account exists. IBAN Validation API. Spends 1 credit of your IBAN Validation plan per request (a failed request counts too); needs the IBAN Validation API key.

abstractapi_validate_vat

Check whether a VAT number is valid and, if it is, return the registered company name and address. VAT Validation API. Spends 1 credit of your VAT Validation plan per request (a failed request counts too); needs the VAT Validation API key.
