aimarket-oracle-core

Shared infrastructure for the alexar76 oracle family — the layer that turns a pure function into a sellable, verifiable capability on AIMarket Protocol v2.

An oracle written on top of this declares its capabilities and its maths. Everything else — the HTTP surface, the signed manifest, priced invoke, Ed25519 receipts, measured latency and success metrics, rate limiting, and hub federation — comes from here.

from oracle_core import Capability, OracleSpec

SPEC = OracleSpec(
    name="Example Oracle",
    product_id="prod-example",
    description="What it sells, in a sentence an agent can choose on.",
    capabilities=[
        Capability(
            capability_id="example.double@v1",
            product_id="prod-example",
            description="Return twice the input.",
            handler=lambda d: {"result": 2 * float(d["value"])},
            input_schema={"type": "object", "required": ["value"],
                          "properties": {"value": {"type": "number"}}},
            output_schema={"type": "object", "required": ["result"],
                           "properties": {"result": {"type": "number"}}},
            price_per_call_usd=0.001,
        ),
    ],
)

Install

pip install aimarket-oracle-core

The distribution is aimarket-oracle-core; the import is oracle_core. The unprefixed name oracle-core on PyPI is an unrelated project that installs a module of the same name — installing it in place of this one fails at ImportError: cannot import name 'Capability' from 'oracle_core'.
