FISL is an HTTP lookup API that maps CIDs to locations, so that a client with a CID can find out where to retrieve it from and who announced it. A client sends a CID, and the index returns the URLs where content can be retrieved, along with the identity of the publisher when known. FISL specifies only the query interface, so it works with any indexing system that supplies location records.
FISL — Finding Internet Structures & Links
FISL is an HTTP lookup that maps a CID to the URLs it can be fetched from. ATFISL publishes those locations on the AT Protocol.
DASL: ATFISL — Content Discovery with the AT Protocol
ATFISL is a content discovery system for CIDs built with the AT Protocol. Publishers announce download locations for CIDs by publishing records to their AT Protocol repositories. Indexers aggregate these records into a lookup table from CIDs to live locations. ATFISL is complemented by FISL which defines an HTTP query API for ATFISL records.
DASL: RASL — Retrieval of Arbitrary Structures & Links
RASL is a URL scheme used to identify content-addressed DASL resources along with a simple HTTP-based retrieval method.
ATFISL — content discovery with the AT Protocol
How ATFISL publishes CID locations as dev.fisl.at records on the AT Protocol: the record, the record key, the Lexicon, and indexing.

A small set of simple, standard primitives to work on content-addressed data.

DASL: MASL — Metadata for Arbitrary Structures & Links
MASL is a CBOR-based metadata system that is designed to work well with content-addressed and decentralised systems, to enable fully self-contained, self-certified content distribution.

DASL: DRISL — Deterministic Representation for Interoperable Structures & Links
DRISL is a serialization format that is deterministic (so that the same data will have the same CID) and that features native support for using CIDs as links. It is based on CBOR, using a narrow profile of CBOR's "Core" featureset called "[[cborc-42]]", specified formally in this IETF document.
Indexing Standard Site - AT Protocol
This guest post from Steve Simkins, creator of Sequoia and docs.surf, outlines the strategy he used to index standard.site records.
DASL: Content-Addressable aRchives (CAR)
The CAR format offers a serialized representation of set of content-addressed resources in one single concatenated stream, alongside a header that describes that content.
Parallel Web Systems | Infrastructure for intelligence on the web
Parallel's new FindAll API turns natural language queries into custom datasets from the web. It finds entities like companies, people, or locations based on your criteria, then enriches them with structured data—all with citations. FindAll Pro achieves 61% recall, 3x better than competitors.
