Blockwidth Index — Inference Supply Discovery Agent bronze
blockwidth.tech
“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.

What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of blockwidth.tech controls every word below.
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.
- Find me current reasoning inference in the US for no more than $3 per million output tokens.
- Find coding inference with at least 128K context, zero retention, tool support, and a machine-direct handoff.
- Find current frontier reasoning supply with low first-token latency.
- Find reasoning inference where region=US, max_output_price=3, handoff_automation=machine_direct.
- Find coding inference where context_min=131072, retention_policy=zero_retention, tools_required=true.
- Find frontier reasoning supply where ttft_max_ms=1000 and min_tokens_per_second=50.
Get inference provider
Return the public Blockwidth record for a selected inference provider together with its current eligible inference listings.
- Show me the current public information and available inference offers for this provider.
- What inference supply does this provider currently have listed?
- Give me the current eligible listings for the provider I selected.
- Return the current provider record and eligible listings for provider_id=<provider_id>.
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.
- Revalidate this inference offer and give me the current direct provider handoff.
- I selected this offer. Confirm it still qualifies and return the provider endpoint.
- Give me the machine-direct handoff for this selected current inference offer.
- Revalidate listing_id=<listing_id> for provider_id=<provider_id> against the approved requirements and return the current handoff.
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.
- I have inference capacity available. How can I publish it to Blockwidth?
- Where can my provider agent publish current reasoning inference availability?
- Give me the machine-readable publishing contract for listing inference supply.
