What is api-platform-state-providers?

A guide for API Platform providers and processors, which separate data retrieval and saving from the application's database entities.

Use it to implement or change API data providers, processors, DTO mappings, operations, validation, security, and persistence behavior.

It reduces direct coupling between API behavior and internal entities, making custom input, output, reading, and writing flows clearer.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00044	$0.00526
Opus 5.5	$0.00018	$0.00210
Sonnet 5.5	$0.00009	$0.00105

Security

Grade A, and why

api-platform-state-providers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

84% identical to api-platform-dto-resources — 39 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Api Platform State Providers (Symfony)

Use when

Reading data from a source other than the default Doctrine provider.
Wrapping the Doctrine provider to post-process results (return a DTO, enforce a tenant scope).
Business logic must run before or after persisting (hashing, slug, dispatching a message).
A v4 read endpoint must dispatch a query or command through a processor.

Default workflow

Implement ProviderInterface::provide() returning iterable|object|null, where null gives a 404 (v3.4 declares mixed).
To keep Doctrine fetching, inject api_platform.doctrine.orm.state.item_provider and api_platform.doctrine.orm.state.collection_provider with #[Autowire].
Implement ProcessorInterface::process() and delegate to api_platform.doctrine.orm.state.persist_processor or remove_processor.
Wire them with provider: and processor: on the resource or the operation; autoconfiguration registers them, and the api_platform.state_provider or api_platform.state_processor tag is only needed without it.
For a processor on GET or GetCollection, add write: true (v4 only).

Guardrails

Run pre-persist logic before calling the inner processor and side effects after it returns.
A processor returns the created or modified object, and nothing for DELETE.
write: true on safe methods is v4 only: v3.4 processors run on write methods only.
DataProvider and DataPersister are v2 interfaces and no longer exist.

Progressive disclosure

Use this file for execution posture and risk controls.
Open references when deep implementation details are needed.

Output contract

The providers and processors added, and the operations they are wired to.
Which built-in services are decorated.
Tests for the not-found, success, and side-effect paths.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
