{"id":807,"name":"Blockwidth Index — Inference Supply Discovery Agent","description":"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.","card_url":"https://blockwidth.tech/.well-known/agent-card.json","endpoint":"https://blockwidth.tech/a2a/v1","protocol_version":"1.0","first_seen":"2026-10-07T09:21:25.084490+00:00","last_verified":"2026-10-07T09:27:55.554430+00:00","card":{"name":"Blockwidth Index — Inference Supply Discovery Agent","skills":[{"id":"find_intelligence","name":"Find inference supply","tags":["inference","inference-supply","inference-discovery","llm-inference","ai-inference","reasoning","coding","availability","provider-discovery","constraint-matching"],"examples":["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."],"inputModes":["application/json"],"description":"Find current provider-declared reasoning and coding inference supply satisfying all supported buyer constraints.
