query_dataset

Read-onlyIdempotent

Paid data access. Returns no records itself: it builds the HTTPS query URL for your filters and returns the x402 payment terms (USDC on Base; amsterdam-events $0.005, security-advisories $0.003, vulnerability-watch $0.003, eu-tenders $0.01, uk-tenders $0.005, eu-funding $0.005, cert-advisories $0.003, eu-medicines $0.005, sanctions-entities $0.005, product-recalls $0.005, eu-legislation $0.005, drug-shortages $0.005, public-holidays $0.002 per call). Send a GET to http_endpoint with an x402 client (v2 PAYMENT-SIGNATURE or v1 X-PAYMENT header) to receive up to 100 matching records; no account or API key. Filters per dataset: amsterdam-events: from, to, district, q, min_visitors, limit, offset; security-advisories: cve, vendor, product, q, added_since, ransomware, min_epss, limit, offset; vulnerability-watch: cve, vendor, product, q, min_cvss, kev, updated_since, limit, offset; eu-tenders: country, cpv, q, deadline_after, deadline_before, published_since, min_value, nature, limit, offset; uk-tenders: nation, region, cpv, q, buyer, deadline_after, deadline_before, published_since, min_value, category, sme, status, source, limit, offset; eu-funding: q, programme, status, type, deadline_after, deadline_before, min_budget, limit, offset; cert-advisories: cve, vendor, product, q, cert, country, type, updated_since, kev, limit, offset; eu-medicines: q, type, category, substance, atc, area, holder, status, flag, shortage, updated_since, limit, offset; sanctions-entities: q, list, type, programme, country, identifier, updated_since, limit, offset; product-recalls: q, country, authority, source, category, classification, firm, allergen, status, since, limit, offset; eu-legislation: type, author, subject, q, celex, amends, published_since, in_force, limit, offset; drug-shortages: q, substance, country, status, since, source, holder, area, limit, offset; public-holidays: country, region, date_from, date_to, year, type, q, limit, offset.

TDQS

A4.6/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds substantial behavior beyond the readOnly/idempotent annotations: it declares that no records are returned, that payment is required with per-dataset USDC pricing, the accepted header versions (v2 PAYMENT-SIGNATURE / v1 X-PAYMENT), the 100-record cap, and that no account or API key is needed. These are exactly the non-obvious operational facts an agent needs before calling.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The critical facts (no records, payment, follow-up GET) are front-loaded and every clause is substantive, but the per-dataset filter enumeration collapses thirteen lists into a single dense paragraph that is difficult to scan or parse. Information-dense but structurally poor.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter tool with an output schema, everything an agent needs is present: what is returned, how to pay, how to follow up, record caps, and the valid filter names per dataset. Nothing material is left unstated.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is already 100%, but the filters parameter is a free-form string map, so the schema alone gives no clue which keys mean anything. The description supplies the complete per-dataset filter vocabulary plus implied limit/offset pagination, which is meaning the schema genuinely cannot convey.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and output ("builds the HTTPS query URL for your filters and returns the x402 payment terms") and immediately negates the wrong expectation ("Returns no records itself"). This cleanly separates it from get_sample and list_datasets, which an agent could otherwise confuse with a data-fetch tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit alternative with its selecting condition: "For free records without filters use get_sample." It also explains the follow-up step (send GET with an x402 client) that must occur after this call, which is genuine routing guidance. It does not explicitly say when list_datasets should be used instead, so it stops short of full when/when-not coverage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
