# RTBlint
> RTBlint is a free, open-source (Apache 2.0) OpenRTB validator. It checks
> real-time bidding bid requests against the published IAB Tech Lab OpenRTB
> specification: malformed JSON, missing required fields, unknown and
> deprecated fields, moved paths, type mismatches, and documented enum values.
> It is version-aware across OpenRTB 2.0 through 3.0, with the deepest rule
> coverage on the dated 2.6 snapshots (2.6-202204 through 2.6-202606). The
> validator runs in the browser (Rust core compiled to WebAssembly) and ships
> as a Rust library and CLI
> (`cargo install rtblint`, `rtblint validate request.json`), a WASM-backed
> npm library (`npm install rtblint-core`), and a hosted MCP server at
> https://rtblint.org/mcp. RTBlint is independent and not affiliated with IAB
> Tech Lab.

## Tools
- [Bid request & response tester](https://rtblint.org/tester/): paste an OpenRTB bid request or bid response JSON and validate it instantly, client-side, with happy and unhappy sample scenarios. Payloads you enter may be stored; see privacy and terms.
- [Privacy](https://rtblint.org/privacy/): how tester and hosted MCP payloads are stored, redacted, opted out of, and used for research
- [Terms](https://rtblint.org/terms/): what submitting a payload licenses; rule development and research that does not publish submitted JSON
- [ARTF simulator](https://rtblint.org/demo/artf/): a simulated Agentic Real Time Framework hop with the real RTBlint engine in the middle. Envelope, mutation set, apply-then-revalidate, forward or drop. Host and agent are fiction; verdicts are not.
- [CLI and library](https://rtblint.org/docs/cli/): rtblint validate, --stdin, --version, --format json, for CI and pipelines, plus the rtblint-core npm library for Node
- [MCP server](https://rtblint.org/docs/mcp/): hosted Model Context Protocol server at https://rtblint.org/mcp exposing validate_bid_request, validate_bid_response, list_openrtb_versions, and get_adcp_capabilities to AI agents. Payloads sent to the hosted endpoint may be stored (identifiers stripped); local rtblint-mcp over stdio does not. Answers AdCP 3.1 capability discovery, declaring the experimental measurement protocol and three bid-stream conformance metrics (openrtb_error_count, openrtb_warning_count, openrtb_conformance_rate)
- [OpenRTB JSON Schemas](https://rtblint.org/docs/json-schemas/): draft 2020-12 schemas per OpenRTB version for bid requests and bid responses, served at https://rtblint.org/schemas/openrtb-<version>-bid-request.schema.json; IAB Tech Lab publishes none for 2.6 or 3.0
## Docs
- [Documentation overview](https://rtblint.org/docs/): rule IDs, tracked versions, issue shape

What verification unlocks
See how your site is discovered—and control what agents see.
- See your website in the map
Review your indexed topics, nearby publishers sharing headings, measured listing exposure and map snapshots in a private report for your website.
- Control what agents see
Edit your listing description, tags, public contact details and additional llms.txt paths. Publish your terms for automated access, attribution and pricing.
- Make your profile eligible for search
A valid, listed, unblocked, verified profile can appear in our publisher sitemap and become eligible for search-engine visibility. Search engines decide what to index and rank.
- Appear in our llms-full.txt
Eligible verified publishers are listed by name, with their file links and summaries, in the service overview agents can read.
Free. No account registration, backlink or payment required. Public discovery remains available without verification.

Claim my listing on Agent Web Map for rtblint.org:
1. POST https://agentwebmap.com/v1/sites/rtblint.org/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://rtblint.org/llms.txt, or use the DNS, meta-tag or well-known method the response describes. This only verifies the listing; your website and domain remain yours.
3. POST https://agentwebmap.com/v1/sites/rtblint.org/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/rtblint.org).
