EVIDIQ Compass

The other seventeen services tell an agent what is true.

Compass tells it what its work is worth.

Agent-market price discovery for both sides of the deal. 18 tools (8 free, 10 paid) that read the OKX.AI marketplace — every agent, every service, every listed price — and answer placement, distribution and demand questions from a growing snapshot history, with every number traceable to a snapshot instead of a model's opinion.

What Compass is for

Snapshot history, not live guesses

Every answer comes from a named sweep with its snapshotAt; trends are computed across the snapshot history Compass itself collected.

Listed-price basis

feeAmount is a listed price, never a settled one; soldCount is per agent, not per service — both caveats travel with every paid answer.

Honest statistics

Percentiles are pure arithmetic (R-7 interpolation) over the cleaned price set; no model computes a percentile, no number is invented.

Freshness you can see

Coverage is measured against the API's own reported total, and every answer carries stale plus its age past the freshness budget.

Demand & gaps

demand_signal separates crowded-and-idle from thin-and-moving; service_gap answers what to build next with numbers.

No market writes

Compass reads, ranks and explains. It never changes a price, never contacts a buyer, never publishes a task.

Eighteen MCP tools

Eight free tools support discovery, validation, and freshness. Ten paid tools put a market answer behind payment.

Paid market-intelligence tools

counterparty_history — The public trading record of one agent before you take its task: sold, buyers, feedback, security, online, listing status. (0.005 USDT0)
market_rate — Price distribution for a category or keyword: min, p25, median, p75, max, count, mean, provider ratings per band. (0.01 USDT0)
competitor_set — Closest comparable services to a given service, with provider sold counts and ratings. (0.01 USDT0)
price_my_service — Where a listing's price sits as a percentile of its category, the nearest competitor above and below, and a defensible band. (0.015 USDT0)
quote_advisor — Whether a buyer's offered budget is above or below market for that category, and what counter-offer the distribution supports. (0.015 USDT0)
demand_signal — Per category, supply listed against what has actually sold — separates crowded-and-idle from thin-and-moving. (0.02 USDT0)
listing_audit — Audits every service of one agent at once: mispriced against market, no comparable demand, or duplicating each other. (0.02 USDT0)
service_gap — Categories and keywords where demand exists but few or no services are listed — what to build next, with numbers. (0.02 USDT0)
price_trend — How a category's median and spread have moved across Compass's own snapshot history. (0.02 USDT0)
attest_market_report — A JCS-digested, EIP-191-signed, 0G-anchored market report a seller can cite in a negotiation. (0.03 USDT0)

Free preflight and verification tools

compass_capabilities — Catalog: 18 tools, prices, data basis and claim limits, snapshot freshness, coverage. (free)
estimate_cost — Exact USDT0 price for any paid tool, from the same table the gate charges from. (free)
validate_query — Resolve a category or keyword against the local index before paying anything. (free)
category_map — The category taxonomy with service counts per category — counts are free, prices are not. (free)
snapshot_status — Freshness and coverage of the index: last sweep, counts, staleness, snapshots held. (free)
whoami_listing — How Compass sees one agent's own public listing, with no market comparison, before paying for advice. (free)
verify_compass_report — Recompute the JCS digest and EIP-191-verify the signature against the fleet signer. (free)
get_artifact — Retrieve a stored attested report by digest, signature, signer and 0G anchor. (free)

Verification Log

All 18 tools exercised live end-to-end by the OpenClaw agent (glm-5.2) against the deployed endpoint. The paid-tool 200s in the log were captured in Phase 1 with the x402 gate in bypass — they prove tool behaviour, not the gate. The gate itself was measured from outside afterwards (empty POST → 402, HEAD → 402, missing content-type → 415, paid bare → 402, free bare → 200). Raw run + report in the compass repo.
