x402
Electronics Calculators – Standard Resistor Value Finder is a paid API for AI agents from electronics-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).
Returns the nearest standard resistor values above and below a target resistance for a chosen E-series (E6–E192), along with percent error for each neighbour.

How this service works
Nearest standard E6, E12, E24, E48, E96 or E192 resistor values to a target, with the percent error of each neighbour.
Output
Returns the closest standard resistor value, the nearest values above and below the target, the percent error for each, the series used, whether the target is itself a standard value, and a comparison across other E-series. Also includes a human-readable summary and verdict.
Example use cases
Closest resistor for prototype design
“I need to use a standard resistor as close as possible to 6800 ohms in the E24 series — what are my nearest options and how far off will I be in percent?”
Checking if a value is already standard
“Is 10k ohms already a standard value in the E96 series, or do I need to pick a neighbour? Show me what's above and below with the error.”
Comparing precision across E-series
“I'm targeting 2.2M ohms — which standard value in the E192 series is closest, and how does that compare to the best E12 option?”
Technical details
Endpoint
GEThttps://electronics-calc.x402tookit.com/resistor-standard?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to snap a calculated or desired resistance to a physically purchasable standard value and want to know how much error is introduced. Ideal for electronics design agents, BOM (bill of materials) generation, or any workflow where a computed resistance must be mapped to a real component. Prefer over manual lookup tables when you need programmatic access to E-series data or want to compare across multiple series simultaneously.
Side effects
- Missing required 'target' parameter returns an error
- Invalid series string (not E6/E12/E24/E48/E96/E192) returns an error or defaults to E24
- Malformed target string (e.g. non-numeric) returns a parsing error
- Very extreme resistance values outside practical range may return degraded or null results
