README

Open Collective for omnisense/omnifund, under any PHP host: a collective read through Open Collective's GraphQL API v2 - its profile and yearly budget, its tiers, its backers. Public data: no key needed.

use Omnifund\OpenCollective\OpenCollectiveFactory;
use Omnifund\Registry;

$registry = new Registry([new OpenCollectiveFactory($httpClient)], [
    'oc' => ['factory' => 'opencollective', 'options' => ['account' => 'webpack']],
]);
$registry->tiers('oc')->tiers();

Options: account (the collective's slug, required), token (a personal token, sent as Personal-Token, optional: it raises the rate limit), endpoint, user_agent.

• Profile: name, description, page, logo, the backers counted, the yearly budget Open Collective estimates (Income by the year). No goal: the API gives none in a stable form.
• Sponsors: the members with the BACKER role, 100 a page (offset), each with since when, its tier and its total given; individuals, organizations, and other collectives as other.
• Tiers: monthly, yearly or one-time; a flexible amount marked as custom, with its minimum.

No library is wrapped: none on Packagist covers Open Collective's API v2.

Terms

Open Collective's Terms of Service and its API documentation. Without a token the API allows 10 calls a minute (answered x-ratelimit-limit: 10): cache what you read; the profile and tiers cost one call, each page of backers one more.

Verified, and not

• Verified on recorded answers (the shapes of live answers of 2026-10-24, the people invented): the profile and its budget by the month, the tiers (fixed, flexible, yearly), the backers page after page, a limit, an unknown collective, the rate limit, the token header sent only when given; BareTest; PHPStan at the highest level.
• Verified live without a key (2026-10-24): webpack's profile, tiers and three backers.
• Not verified: a personal token.
