§SELF — protocol specification
## §SELF — OIP protocol specification

**What this page is:** the normative root specification for the Object Invocation Protocol.

**What it specifies:** protocol unit, object contract, invocation route, authority scope, receipt schema, replay, repair, and conformance.

**Read:** https://miscsubjects.com/a/oip-capability-http-fetch
**Machine bundle:** https://miscsubjects.com/api/articles/oip-capability-http-fetch/bundle?format=markdown
**Live object tree:** https://miscsubjects.com/api/dispatch?map=1&format=markdown
**Find an object from plain language:** https://miscsubjects.com/api/dispatch?ask=<what you want>
**Read one object:** https://miscsubjects.com/api/dispatch?key=<KEY>&format=markdown

**Proof rule:** an action is not proven by intent, description, or a 200. It is proven by the ledger and the OIP receipt for the invocation.

HTTP_FETCH

This is one executable OIP object. It is the leaf where prose stops and exact invocation begins.

Universal HTTP fetch. Method GET/POST/PUT/PATCH/DELETE. body is the raw request body string (empty for GET). headers_json is optional JSON header overrides. Returns 'HTTP <status>:<body first 20000 chars>'. Authorization redacted in ledger

Parent system: HTTP. Root: /a/oip. Machine doc: /api/dispatch?key=HTTP_FETCH&format=markdown. Invocation history: /api/invocations?object_id=HTTP_FETCH.

Invoke

Example: [HTTP_FETCH]<method>|<url>|<body>|<headers_json>[/HTTP_FETCH]

Run URL: https://miscsubjects.com/api/dispatch?invoke=HTTP_FETCH&body=%3Cmethod%3E%7C%3Curl%3E%7C%3Cbody%3E%7C%3Cheaders_json%3E&share=<TOKEN>

Auth: none. Risk: low.

Machine contract

  • Read this article first; do not infer the row shape from memory.
  • If acting with a URL-only tool, open run_now after replacing placeholder args.
  • If the call returns ran:false or proof.ok:false, read the receipt and repair the failed invocation instead of narrating success.
  • If the token denies the call, report the denial exactly; do not switch to a broader action unless the owner supplied a broader token.

Troubleshooting

  • unknown key - Use the did_you_mean links or ask URL; never guess another key.
  • argument/body mismatch - Read inputs/example_args here, then retry with repairs: inv_ID so lineage closes.
  • expired or corrupted token - Report token_expired/token_corrupted from the response; owner mints a fresh scoped link.
  • tool returned ok:false / exit nonzero - Do not call it sent. Read the receipt, correct the body, fire a repair.

Receipt loop

After any action, open the receipt. If it is wrong, repair it with POST /api/dispatch {key, body, repairs:"inv_ID"}. If you need to repeat the exact recorded call, replay it with POST /api/dispatch {replay:"inv_ID"}.

Principle: Self-explaining payload — no external context required. This _self block is the capability: what it is, how to run it, how to change it, and where to look next. Path: OIP > HTTP > HTTP_FETCH Capability: HTTP_FETCH — Universal HTTP fetch. Method GET/POST/PUT/PATCH/DELETE. body is the raw request body string (empty for GET). headers_json is optional JSON header overrides. Returns 'HTTP <status>:<body first 20000 chars>'. Authorization redacted in ledger When to use: you need to http fetch RUN NOW (open this URL): https://miscsubjects.com/api/dispatch?invoke=HTTP_FETCH&body=%3Cmethod%3E%7C%3Curl%3E%7C%3Cbody%3E%7C%3Cheaders_json%3E&share=<TOKEN> Example call: [HTTP_FETCH]<method>|<url>|<body>|<headers_json>[/HTTP_FETCH]

  • type · runner: tool · edge · util
  • run it: Open run_now (URL, fires the example), or POST https://miscsubjects.com/api/dispatch {"key":"HTTP_FETCH","body":"<method>|<url>|<body>|<headers_json>"}. From the router: [HTTP_FETCH]arg1|arg2|arg3|arg4[/HTTP_FETCH]
  • inputs: {"args":"method|url|body|headers_json"}
  • outputs: { ok, result, invocation, yield, _self } — result is this object's output; yield is tokens/cost/material; invocation is the ledgered record.

Logical proof (verify each step)

  1. Every capability is an invokable object with its own _self — this block. → https://miscsubjects.com/api/dispatch?key=HTTP_FETCH
  2. You run it by POSTing to /api/dispatch; in a model turn the router tag is [HTTP_FETCH]args[/HTTP_FETCH]. → https://miscsubjects.com/api/dispatch?registry=1
  3. Every invocation is ledgered with actor, cost, and material/waste. → https://miscsubjects.com/api/invocations?object_id=HTTP_FETCH
  4. You can ask the build for capabilities in plain language. → https://miscsubjects.com/api/dispatch?ask=Universal%20HTTP%20fetch.%20Method%20GET%2FPOST%2FPU
  5. The whole build is one self-describing map, with the terminal key. → https://miscsubjects.com/api/dispatch?build=1
