title: Glyph Mints API
description: 'A language for agents: encode content into the cheapest substrate the reading model can parse, with honest per-reader token math. Fillin is the retrieval product — a time-series index of the dev internet that closes the gap between an LLM''s training cutoff and now.'

post:
summary: Create Mint
description: 'Mint an information asset. Returns the signed mint payload.
Fillin verifies every `evidence[].chunk_id` resolves to a real corpus
row, validates the typed reasoning graph, then HMAC-signs the canonical
payload. The returned `attestation` is what buyers verify; it''s also
what makes the asset listable on the marketplace.'

is visible so we can prove the attestation contract end-to-end.'

credits the seller''s bearer minus Fillin''s rake, records the transaction,
and returns the full mint payload (the typed reasoning_graph that was
paywalled to non-buyers in the future read endpoint).
Bearer-funded buyers only in MVP. Wallet-funded buyers will be added
once x402-out is wired; the seller MUST be a bearer-minter so we have
a SQLite balance to credit.'
