Document parse

Any invoice, receipt, EOB, ERA, or COI — PDF or image — into structured, validated JSON.

POST /v1/parse$0.10/document · 10 credits, charged only on success

Send this

  "fileUrl": "https://…/invoice.pdf"
}

Every response carries usage — the credits burned and your remaining balance. A failed call never burns credits.

Try it live against your own key in the interactive reference; every account gets 500 free credits a month, no card.
