_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • cable_conductor_mass unknown never probed

    Conductor mass is calculated from nominal cross-section, core count and length against the material density; for a nominal cross-section this is exact and independent of stranding. Total cable mass and the copper share are returned as a range derived from published manufacturer weight tables per cross-section band, not as a type-test value. Insulation, filler and armour are not modelled individually. Concentric conductors (NYCWY) are only included if concentric_conductor_mm2 is supplied; otherwise the field stays null and is named in unavailable_fields. No market price is applied here. Preis 0.002 USDC je Aufruf, Abrechnung über x402.

  • dhl_shipping_label unknown never probed

    Sends one domestic German shipment to the official DHL Parcel DE Shipping v2 API. Validation-only is the default and causes no DHL state change. Test-label creation is permitted only in the configured sandbox; production creation stays disabled unless the operator explicitly enables it. Address and contact values are forwarded to DHL solely for this request and are never archived by HALOWERK. The caller confirms authority and any consent required for forwarding recipient data.

  • scrap_purchase_margin unknown never probed

    Takes the gross lot weight, the purchase price paid per kilogram of gross weight and the sales price per kilogram of recovered metal, then applies recovery yield and melting loss for the scrap grade. Yield and loss default to practice values per grade and can be overridden. Handling, transport and disposal cost are optional flat amounts. The endpoint applies no market price and fetches none: sales_price_eur_per_kg is supplied by the caller. Currency is treated as a label only, no conversion is performed.

  • awg_metric_convert unknown never probed

    Uses the geometric AWG definition, so results are exact for solid round conductors. Mass per metre and resistance follow from the material density and resistivity at 20 degrees Celsius; stranded conductors carry roughly two to five percent more mass and resistance per metre than the same nominal size and are not modelled separately. Supply either awg or cross_section_mm2, not both. Sizes 4/0 through 40 AWG are covered. Preis 0.001 USDC je Aufruf, Abrechnung über x402.

  • cable_type_vision unknown never probed

    Downloads one HTTPS image through the hub SSRF guard, then asks the configured OpenAI vision model for strict structured JSON. It reports observed features and readable markings, at most five ranked type candidates, and conductor material, core count or cross-section only where the image supports them; unknown values remain null or unknown. The result is identification assistance, not an electrical safety clearance, approval, voltage-state determination or substitute for inspection and testing.

    Multiplies the copper quantity by literature emission factors for the chosen secondary route and for primary cathode production, and reports the difference as low, typical and high. The factors are published life cycle averages and are stated in the response; they are not a certified product carbon footprint and are not a valid basis for a carbon credit, a customer declaration or an audited claim. Transport of the scrap to the plant is excluded unless transport_km and transport_factor_kg_co2e_per_tkm are supplied. Both factors can be overridden with own verified values.

    Returns published content ranges per board class multiplied by the lot mass. The spread between low and high is wide and real: content depends on board generation, manufacturer and how much of the assembly is included. This is a planning estimate for sorting and pre-valuation, not an assay, not a settlement basis and not a substitute for a sampled analysis. Values are only calculated when price_eur_per_g is supplied by the caller; no metal price is retrieved or resold here.

  • dhl_tracking unknown never probed

    Queries the official DHL Parcel DE Tracking API for one shipment and returns a privacy-minimized result: current status, timestamps and codes, product, delivery estimate, countries and any public event history supplied by DHL. The caller must be the sender, recipient or an authorized party and confirm all required consent; tracking data must not be combined with advertising. Recipient and sender names, street addresses, email addresses, signatures and proof-of-delivery documents are never returned or retained. Delivered shipments are marked locally by a keyed hash and are not queried from DHL again. Preis 0.004 USDC je Aufruf, Abrechnung über x402.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
