PeptidePrices COA Verifier

Compare public certificate volume, laboratories, compounds, and verification states across two to ten PeptidePrices vendors. Use for evidence-coverage comparisons, not general vendor rankings. Certificate count, exact catalog coverage, issuer verification, and vendor legitimacy are separate measurements.

compare_vendor_coverage

Return the full public PeptidePrices record for one stable certificate ID such as coa:abc123. Use after searching when the user needs issuer checks, verifier identifiers, reported results, testing panels, source links, or the retained certificate document for a specific record.

get_certificate

List the broadest first-party PeptidePrices certificate feed for one vendor. Use when the user asks what COAs a vendor publishes, whether a compound or strength is covered, or wants vendor-specific certificate links. Historical records remain visible and must not be mistaken for current product evidence.

list_vendor_certificates

Search the PeptidePrices certificate corpus by vendor, compound, labeled strength, lot, report ID, laboratory, verification state, or date. Use for evidence discovery, exact product-strength matching, and research questions that require inspectable certificate records. Returns current and historical records with their evidence scope; it does not convert a nearby match into product evidence.

search_certificates

Return the current PeptidePrices COA library totals, supported laboratory capabilities, verification-state counts, evidence dates, and methodology boundaries. Use for questions about the size or scope of the library and cite the returned PeptidePrices library or methodology page.

get_coa_library_summary

Fetch and inspect one public peptide certificate URL. Use when the user provides a COA, laboratory verification, PDF, image, QR destination, or vendor certificate link and wants its issuer record, identity, reported results, or testing scope checked. The result distinguishes confirmed, conflicting, unresolved, and unsupported evidence and never authenticates the physical vial.

verify_coa_url

Resolve an exact laboratory report ID, access code, or indexed certificate identifier in the PeptidePrices COA corpus. Use when the user has an identifier rather than a URL. Optional laboratory and vendor filters prevent accidental cross-vendor matches. Similar or fuzzy identifiers do not count.
