能力清单

工具	说明
sales.ask	Ask anything about this API: what commodities are covered, how on-chain provenance works, pricing tiers, x402 payment flow, MCP integration, or the Extract API. Free to call. Returns a natural-language answer from a small LLM grounded on the API docs.
benchmark.commodity	Returns USGS Mineral Commodity Summaries benchmark data for one of 8 critical minerals (copper, gold, silver, lithium, cobalt, nickel, manganese, graphite). Each response includes grade cutoffs, spot pricing, process-recovery benchmarks, production statistics, and an EAS attestation UID + IPFS CIDs anchoring the data on Base. Costs $0.10 USDC per call via x402 when invoked through the REST endpoint; this MCP tool surfaces the same data for discovery.
benchmark.ultrasound	Returns attested field run logs for an ultrasound-assisted gravity-separation device (grooved stainless-steel tray). Each run includes feed parameters, ultrasound frequency, tray geometry, gold recovery rates, and an EAS attestation UID anchoring the record on Base. Costs $0.10 USDC per call via x402 when invoked through the REST endpoint; this MCP tool surfaces the same data for discovery.
extract.estimate	Free probe + price quote for paid structured-data extraction from a public document URL (pdf_digital, pdf_scanned, image, csv, txt). Returns estimate_id, source_type, page/row count, quality_floor grade (A/B/C/D), cost_breakdown {est_input_tokens, est_output_tokens, model_cost_usdc, margin_x, price_usdc}, and 15-min expires_at. Use the estimate_id with extract.run to pay via x402 USDC on Base. Honest grading: jobs returned as grade D receive an 80% auto-refund.
extract.run	Returns invocation guidance for executing a paid extraction job after extract.estimate. Payment is x402 USDC on Base, amount equals cost_breakdown.price_usdc from the estimate (clamped onto the 5-tier ladder: $0.10 / $0.50 / $1.00 / $2.50 / $5.00). Result delivery: job_id + result + grade (A/B/C/D) + result_url. Grade D triggers 80% auto-refund. MCP cannot carry the X-PAYMENT header, so this tool returns the endpoint + price; execute the paid POST directly with an x402 client (x402-fetch, x402-axios).
extract.result	Fetch the structured extraction result for a previously paid job. Returns job_id, grade (A/B/C/D), and the assay-extract-v0.1 result document (samples, doc_type, lab, report_date, OPSEC-rounded coords, raw_text). Requires the HMAC token from result_url. Result TTL is 24 h after the paid run completes.
