teckel: AI Toolkits Pricing

How billing works. MCP/API billing accrues per call in real time, but is aggregated hourly in the teckel billing system — recent calls won’t show in your balance or statements until the next hourly cycle.

Awaited, not fire-and-forget. Every Toolkit function must be awaited by the client to receive the response; set client timeouts to allow for the required response times.

Check your balance. Every Toolkit can return the teckel credit balance for the Ethereum address tied to your API key — ask “What is my teckel credit balance?”, or call get_teckel_credit_balance_for_apikey.

Price / call 3350 tc · ≈ £0.07 per 10 calls	`driving_distance_between_coords`	lat1 Latitude (decimal degrees, positive North) of start location lon1 Longitude (decimal degrees, positive East) of start location lat2 Latitude (decimal degrees, positive North) of end location lon2 Longitude (decimal degrees, positive East) of end location
driving_distance_between_places Get the driving distance (in kilometers) and time (in hours) between two places specified by name, address, etc. Accounts for traffic conditions and incorporates ferry trip if water crossing required. Price / call 3350 tc · ≈ £0.07 per 10 calls	`driving_distance_between_places`	search_address1 Start location specified as a place. Can be any named place, landmark, address, postcode etc. Global coverage. search_address2 End location specified as a place. Can be any named place, landmark, address, postcode etc. Global coverage.
flight_route_calculations Perform VFR (Visual-Flight-Rules) flight route calculations between specified origin and destination airfields, plus up to ten optional intermediate waypoints (when not routing direct). Utilizes various functions in the toolkit to prepare the route, then performs detailed analysis, as summarised in the introduction to the toolkit above. An example call showing the detailed output fields is presented below this table. Price / call 30000 tc · ≈ £0.06 per call for a single leg, plus 0.057 per additional leg.	`perform_flight_route_calculations`	origin Departure airfield. Can be the name, ICAO code, IATA code or alternate identifier. Alternatively, just specify the latitude,longitude pair. destination Destination airfield. Can be the name, ICAO code, IATA code or alternate identifier. Alternatively, just specify the latitude,longitude pair. altitudeFeetAverage Altitude above mean sea level (AMSL), in feet, for the route (use an average that can be applied to the entire route). If blank, will assume default value of 2500 ft iasKtsAverage Indicated Airspeed (IAS) in knots, for the route (use an average that can be applied to the entire route). If blank, will assume default value of 100kts. fuelFlowPerHourAverage Fuel consumption, in units per hour (can be any typical value referring to gallons per hour, litres per hour, etc), for the route (use an average that can be applied to the entire route). The computed fuel used will be in the same units. If blank, will assume default value of 8 gallons per hour. departMinutesFromNow Planned departure time, expressed in minutes from now rounded to nearest 5 minutes. In order for the real-time weather computations to remain valid, it is recommended to keep this value within an hour or two (ie less than 120 minutes) intermediateWayPoint1 Optional (if the route is not direct between the origin and the destination). Can be a place name, address, etc., or an airfield name, ICAO code, IATA code or alternate identifier (if overflying an airfield en route). Alternatively, can be a latitude,longitude pair. This is convenient for specifying the waypoint as a bearing/range relative to the origin — or to any other location such as a navigational aid — via the `nav_bearing_from_coords` or `nav_bearing_from_place` tools. Leave blank if not used. intermediateWayPoint2 Optional. Same but for second intermediate waypoint. Requires `intermediateWayPoint1` to have been specified (i.e., not blank). intermediateWayPoint10 Optional. Same but for the tenth intermediate waypoint. Requires that all nine preceding intermediate waypoints have been specified (ie., none blank). Note: ten is the maximum number of intermediate waypoints which can be specified.

Some functions make nested calls to other functions; each nested call is billed separately. For MCP calls via LLMs, the LLM’s own fees are charged by the MCP client app and are not included above. Where a function uses an external third-party service (e.g. Google APIs), teckel pays that fee and re-charges it within the call fee. tc are priced in GBP — peg £1 = 500,000 tc (1 million teckel credits = £2.00; bulk discounts up to 12.5% on larger top-ups — see our Pricing page).

IPFS Toolkit

10 functions — pin, list, fetch and remove encrypted IPFS content.

Pricing. Pay-as-you-go by storage: 20,500 tc per GB uploaded and 48 tc per GB-hour stored.

Name & Description (for MCP clients)	Underlying method (for RESTful API calls)	Parameters
list_ipfs_files List IPFS files (selected on nickname via fuzzy `search_string`) for the account corresponding to the teckel API key used in the call. Optional filters by pinned state, encrypted state, and content type.	`get_ipfs_content_for_apikey`	search_string Search for this string in the file nickname. Leave blank to return all entries. pinned_state 0 = all entries; 1 = pinned only; 2 = unpinned only. Default 0. encrypted_state 0 = all entries; 1 = encrypted only; 2 = unencrypted only. Default 0. content_type Filter by content type, e.g., 'image', 'audio', 'video'. Leave blank to ignore.
remove_ipfs_files Unpin and remove the IPFS files (selected on nickname via fuzzy `search_string`) from the teckel IPFS node and from the wallet account, for the account corresponding to the teckel API key used in the call. Note: this only removes the content from the teckel node and inventory. It may still exist on the IPFS decentralised network.	`remove_ipfs_files_from_account`	search_string Search for this string in the file nickname.
