Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 1 Feb 2027 as of our check on 10 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE1 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 6 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of orvik.app controls every word below.

Narrow an identification key

Given observed traits, return the entries of a key consistent with them — as possibilities, never as an answer.

identificationnaturefield-guide

Examples it gives

what caterpillars are green with a horn
black feather with white bars

Look up occurrence data

GBIF and iNaturalist record counts, seasonality corrected for observer effort, mineral hardness, fossil age ranges.

gbifinaturalistoccurrencephenology

Examples it gives

how many records of Latrodectus mactans
when are luna moths reported

Run a field calculator

Tree age from circumference, pet age in human years, coin melt value, a Mohs scratch bracket, or a sowing calendar.

calculatorarboriculturenumismaticsmineralogygardening

Examples it gives

age of a 120 cm white oak
melt value of ten pre-1965 quarters

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.

Orvik identification key entries

json

749 catalogued specimens with trait coding, the diagnostic character that separates each from its lookalikes, and joined occurrence counts. Narrows possibilities; never returns a determination.

https://orvik.app/api/v1/key-entries.json

Orvik open field data

json

Occurrence counts for 570 taxa and specimens joined from GBIF, iNaturalist, Macrostrat and PaleoBioDB, with the observer-effort baseline needed to read the month histograms honestly. Snapshot 2026-09-04.

https://orvik.app/api/v1/field-data.json

Orvik field reference tables

json

ISA tree growth factors, AAHA pet life-stage bands, mint metal content for 22 coins, the Mohs scale with household scratch tools, and sowing timing for 34 crops — each with the caveat that makes it usable.

https://orvik.app/api/v1/reference-tables.json

Orvik free browser tools

json

23 filterable identification keys and 5 field calculators, with the facets each key can filter on. Free, no account, nothing uploaded.

https://orvik.app/api/v1/tools.json

What Orvik does and does not do

json

The product: subjects covered, what the free web tools do without an account, which services process photographs, and an equally long list of what it does not do.

https://orvik.app/api/v1/orvik.json

Orvik MCP server

json

Read-only MCP tools over the keys, the occurrence data and the five field calculators. No authentication, nothing written, no user data.
