Single Constant Lookup

Operators, constants, equations, experiments — the registry surface.

  • Protocol ID — physical-constant
  • Category — Data
  • Endpoint — GET /api/framework/constants/:key
  • Auth — none
  • Rate limit — 120/min
  • Version — 1.287.6
  • Precision — ≤0.1% (KO42-enforced)

What it does​

Look up a single physical constant by key.

Signature​

Request​

GET /api/framework/constants/:key
ParamTypeRequiredDefaultDescription
keystring✓—Constant key: c, G, h, h_bar, k_B, e_charge, m_electron, etc.

Response​

{ key, value, unit, name, exact }

Runnable example​

curl -sS \
  "https://api.zeq.dev/api/framework/constants/:key"

Integrate​

  1. Introspection — list what the kernel can compute before authoring a wizard step.
  2. Schema generation — feed returned operator definitions into typed bindings in any language.
  3. Experiment catalog — wire the response into a UI selector for reproducible demos.

Seeds​

  • Near — wrap /api/framework/constants/:key in a language SDK so builders can call it in three lines.
  • Medium — publish a reference integration demonstrating Single Constant Lookup alongside a real workload, with pulse-aligned metrics.
  • Far — propose Single Constant Lookup as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.

Papers​

Middleware active. Kernel on the 1.287 Hz HulyaPulse. Awaiting next Zeqond.
