## API and agent access
- [API documentation](https://docs.postonce.to): The public API uses scoped bearer API keys. Social-account OAuth connections do not grant API access.
- [OpenAPI specification](https://postonce.to/api/openapi.json): Endpoints and request/response contracts.
- [API permissions metadata](https://postonce.to/.well-known/oauth-protected-resource/api/public): Supported scopes and bearer transport for the public API; this metadata does not advertise an OAuth authorization server.
- [MCP setup](https://postonce.to/integrations): Connect supported AI clients to the hosted Streamable HTTP endpoint at https://postonce.to/mcp. Use the client-specific setup instructions for OAuth or a manual scoped API key. Connecting social accounts is a separate step.
- [MCP OAuth discovery](https://postonce.to/.well-known/oauth-protected-resource/mcp): OAuth protected-resource metadata for the hosted MCP server, including its authorization server at https://postonce.to/api/oauth.
- [MCP documentation](https://docs.postonce.to/mcp/docs): Account discovery, publishing, delivery verification, media uploads, and automatic crossposting workflows. Existing plan access and credential scopes apply.

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.
Let your coding agent verify it
If your coding agent is authorized to manage this website, paste these instructions into it.
Claim my listing on Agent Web Map for postonce.to:
1. POST https://agentwebmap.com/v1/sites/postonce.to/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://postonce.to/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/postonce.to/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/postonce.to).
MCP equivalent: tools begin_ownership_claim, then verify_domain, at https://agentwebmap.com/mcp. Docs: https://agentwebmap.com/docs#verifyCorrections or removal requests: contact the directory.
