API reference
Get a fact's proof bundle
Get the cryptographic proof bundle for one fact: the capture behind it (content-addressed sha256), its merkle inclusion path in a hash-chained manifest, and the OpenTimestamps proof anchoring the batch in the Bitcoin blockchain. Verify offline with bixel-verify — zero trust in Bixel required. Attests observation-at-time, never extraction correctness.
Path Parameters
company*string
Apex domain (canonical, e.g. pinecone.io). Bare values are resolved as legacy slugs. Unknown names: resolve via /v1/search first.
key*string
The fact key, e.g. pricing.tier.standard.monthly_usd.
Query Parameters
provenance?string
Selects between provenance twins of the same key; default prefers observed.
Value in
- "observed"
- "company_stated"
